Q: Is this a genuine Zurn kit?A: This is a high-quality aftermarket replacement kit manufactured to OEM specifications. Q: Do I need special tools to install this kit?A: Basic hand tools are sufficient — typically a screwdriver and adjustable wrench. The check modules unscrew from the valve body. Q: How often should I rebuild my backflow preventer?A: Typically every 5 years, or whenever it fails annual certification testing. More frequent in areas with hard water or high chlorine. Q: Does this include the check module assemblies?A: This kit includes rubber components (discs, diaphragm, O-rings) — not the plastic check modules themselves. If your modules are cracked, you'll need complete replacement modules.

Product Overview The 6 Port Module with Valve Shell O-Ring for Paramount Pool Systems 004302440800 is a precision-engineered replacement part designed to restore proper function and stop leaks in your pool or spa equipment. Manufactured to meet or exceed OEM specifications, this component delivers reliable, long-lasting performance at a fraction of the dealer price. Pool equipment operates in a harsh environment — constant exposure to chlorinated water, UV radiation, temperature swings, and pressure cycles. When seals, O-rings, and internal components degrade, the result is leaks, poor filtration, and higher operating costs. Key Features OEM-Spec Precision: Manufactured to exact dimensional tolerances for guaranteed fit without modifications. Chemical-Resistant Materials: EPDM, Viton, or chemical-grade polymers resist degradation from chlorine, bromine, salt, and UV. Extended Service Life: Premium materials deliver 2-3x the service life of economy alternatives. Easy DIY Installation: Straightforward replacement with basic hand tools — most jobs take 15-30 minutes. Value Pack Savings: Multi-pack options available — stock up and save vs buying singles when applicable. Compatibility Specification Detail Brand Paramount In-Floor Cleaning Systems Replaces Part # 004302440800, 004-302-440-800 Material EPDM Rubber / Engineered Polymer Application Residential & Light Commercial Pool/Spa When to Replace Visible Leaks: Water seeping from connections or housings = failed seal or gasket Decreased Performance: Reduced flow, poor filtration = worn internal components Unusual Noise: Grinding or squealing = worn bearings, gears, or impellers Age: Rubber seals should be replaced every 2-3 years as preventive maintenance Hard/Cracked Rubber: O-rings that feel hard or show surface cracks no longer seal properly Installation Tips Turn Off Equipment: Switch off at circuit breaker before working on pool equipment. Release Pressure: Open air relief valve on filter to release system pressure. Clean All Surfaces: Remove old gasket material and debris — clean surface = proper seal. Use Proper Lubricant: Silicone-based pool lube only. NEVER use petroleum jelly — it destroys EPDM. Tighten Evenly: Cross-pattern tightening for multi-bolt connections. Test Before Full Operation: Run briefly and check all connections. Frequently Asked Questions Q: How do I know if my 6-port module needs replacement?A: Symptoms: pop-up heads staying up or not popping up, uneven cleaning coverage, gear grinding noise from valve, water leaking from housing, pop-ups cycling wrong order. If cleaning coverage decreased noticeably, module gears are likely worn. Q: Is this genuine Paramount?A: Premium aftermarket replacement manufactured to meet or exceed Paramount OEM specifications. Fully compatible with Paramount PCC-2000, PV3, and Cyclean in-floor systems using 004302440800 module. Q: Can I install this myself?A: Yes — straightforward DIY. 1) Turn off pump 2) Remove valve lid (6-8 screws) 3) Lift out old module 4) Install new O-ring on valve shell 5) Drop in new module aligning drive pin 6) Replace lid evenly 7) Run pump to test. 15-20 minutes. Q: Will this fit older Paramount systems?A: Fits Paramount in-floor systems from 1990s through current models using 6-port water distribution valve. Compatible with PCC-2000, PV3, Cyclean, and SDX. If your system uses 8-port valve, this is NOT compatible.

Product Overview The iFJF Engine Valve Cover pair is a direct OEM-spec replacement for the 5.6L V8 VK56DE engine in 2004-2015 Nissan Titan, Armada, 2008-2012 Pathfinder, 2004-2010 Infiniti QX56, and 2012-2021 NV2500/3500. Includes driver-side (13264-ZE01A) and passenger-side (13264-ZE00A) covers with pre-installed gaskets. Built from high-grade reinforced polymer rated for heavy-duty truck and SUV applications. Key Features Complete V8 Pair: Includes Driver Side (13264-ZE01A / 13264-7S010) and Passenger Side (13264-ZE00A / 13264-7S000) — both cylinder banks in one kit. Pre-Installed Gaskets & Tube Seals: Factory-installed rubber gaskets and spark plug tube seals on both covers — ready to bolt on. VK56DE V8 Specific: Designed for the Nissan/Infiniti 5.6L V8 platform — correct bolt pattern, PCV routing, oil baffle placement, and sensor ports. Heavy-Duty Construction: Reinforced polymer rated for the high heat output of the VK56DE under towing and heavy load conditions. QC Inspected: Every cover is individually checked for gasket seating, port alignment, and surface flatness before shipment. Compatibility Table Year Make Model Engine 2004-2015 Nissan Titan 5.6L V8 VK56DE 2004-2015 Nissan Armada 5.6L V8 VK56DE 2008-2012 Nissan Pathfinder 5.6L V8 VK56DE 2004-2010 Infiniti QX56 5.6L V8 VK56DE 2012-2021 Nissan NV2500/3500 5.6L V8 VK56DE Specifications Specification Detail Part Number FJ-EVC08 Driver Side OEM 13264-ZE01A, 13264-7S010 Passenger Side OEM 13264-ZE00A, 13264-7S000 Material Reinforced Heat-Resistant Polymer Gaskets Pre-Installed (Both Covers) Engine Nissan VK56DE 5.6L V8 Warranty 12-Month Manufacturer Warranty Why Choose iFJF? The VK56DE V8 is a workhorse — but its valve covers are a known weak point. As mileage accumulates, gasket degradation leads to oil seepage, spark plug tube flooding, and catalytic converter contamination. Nissan dealers charge $700+ for parts. Our iFJF pair provides the same fit and durability at a fraction of the cost. Ideal for Titan and Armada owners who tow, haul, and demand reliability. Installation Tips Disconnect battery and remove engine cover for access. Passenger side is straightforward; driver side may require moving brake booster vacuum line. Clean mating surfaces with brake cleaner and plastic scraper — avoid metal on aluminum. Torque cover bolts to 74 in-lbs (8.4 Nm) in factory sequence. Replace brittle PCV hoses during reassembly to prevent vacuum leaks. Frequently Asked Questions Q: Will these fit my 2007 Nissan Titan 5.6L?A: Yes. Direct fit for all 2004-2015 Titan with the 5.6L V8 VK56DE engine. Q: Are the gaskets pre-installed?A: Yes. Both covers arrive with rubber gaskets and spark plug tube seals factory-installed and ready to install. Q: What are VK56DE valve cover failure signs?A: Oil smell from engine bay, visible leaks at cover edges, oil-fouled spark plugs (misfires P0300-P0308), and white/blue smoke from oil on hot exhaust manifolds. Q: Can I replace just one side?A: We strongly recommend replacing both. If one side is leaking, the other's gaskets are equally aged. Doing both saves labor and ensures even sealing. Q: DIY difficulty?A: Intermediate. Passenger side is easy; driver side needs maneuvering around brake booster. Budget 3-5 hours with basic metric tools and torque wrench. Q: OEM quality comparison?A: Meets or exceeds OEM specifications for the Nissan/Infiniti parts (13264-ZE01A/ZE00A). Same fit and durability at significant savings.

GP77759 Mixer Balance Cap Stem — Kohler Rite-Temp Replacement The iFJF GP77759 mixer balance cap stem is a precision-machined replacement for worn or leaking Kohler Rite-Temp valve stems. When water starts seeping from around your shower handle or the temperature adjustment becomes imprecise, this component is often the root cause. Direct drop-in replacement — no modifications needed. Key Features Precision-Machined Brass Stem: Corrosion-resistant brass construction for decades of reliable service OEM-Spec Fit: Identical dimensions to Kohler GP77759 for seamless installation Complete Stem Assembly: Includes stem, O-rings, and seals — ready to install Smooth Temperature Control: Restores precise hot/cold mixing at the handle Leak-Free Seal: Fresh O-rings eliminate handle-area water seepage DIY Installation: Replaces in 10–15 minutes with basic hand tools Compatibility Brand Valve Series Size Kohler Rite-Temp K-304 1/2" Kohler Rite-Temp K-8300 Series 1/2" Specifications Specification Value Part Number GP77759 Stem Material Brass Valve Compatibility K-304, K-8300 Series Connection 1/2" Includes Stem, O-rings, seals Signs You Need a New GP77759 Water dripping from behind the shower handle Temperature dial feels loose or doesn't stay in position Difficulty finding the right water temperature mix Visible corrosion or mineral buildup on the existing stem Handle spins freely without changing water temperature Installation Steps Turn off water supply to shower valve Remove the shower handle (typically a set screw underneath) Remove the trim/escutcheon plate Unscrew and remove the old GP77759 stem using an adjustable wrench Clean the valve body threads and seating surface Apply plumber's grease to the new stem O-rings Thread the new GP77759 stem into the valve body — hand-tighten first, then 1/4 turn with wrench Reassemble the trim plate and handle Turn water back on and test for leaks and smooth operation Frequently Asked Questions Q: Is this just the cap/stem, or does it include the cartridge too? A: This is the GP77759 mixer balance cap stem only. For a complete rebuild including the pressure balancing cartridge, see our GP76851 combo kit. Q: Will this fit my K-8304 shower valve? A: Yes, the GP77759 fits all Kohler Rite-Temp K-304 and K-8300 series 1/2" pressure balance valves. Q: Can I replace just the O-rings instead of the whole stem? A: While possible, the brass stem itself wears over time. Given the low cost of this complete assembly, replacing the entire stem ensures a reliable, long-lasting fix. Q: How tight should I install the new stem? A: Hand-tighten until snug, then add no more than 1/4 turn with a wrench. Overtightening can crack the valve body or strip the threads.

385316906 Vacuum Breaker Kit for Sealand Traveler Toilets — Leaking Stopped, No Sprayer Stop your Sealand Traveler RV toilet from leaking with this OEM-grade vacuum breaker repair kit (part number 385316906). Designed specifically for Traveler series toilets WITHOUT the hand sprayer hookup, this kit replaces the worn internal seals and components that cause water leaks, backflow issues, and inconsistent flushing. Whether you're dealing with a slow drip that won't stop or water backing up into the bowl, this kit provides a complete, lasting repair at a fraction of the cost of a new toilet. Key Features OEM-Spec 385316906 Replacement: Manufactured to exact Sealand/Dometic specifications for a guaranteed fit on Traveler series toilets without the hand sprayer option Complete Sealing Kit: Includes vacuum breaker, o-rings, gaskets, check valve components, and all internal seals needed for a full rebuild Stops Water Leaks: Addresses the two most common leak sources — the vacuum breaker seal failure (leaks at the back of the toilet) and check valve deterioration (water leaking into the bowl) Prevents Backflow: Restores proper one-way water flow, preventing contaminated bowl water from siphoning back into your RV's fresh water system DIY-Friendly Installation: Clear, illustrated instructions included — most RV owners complete this repair in 30-45 minutes with basic hand tools Compatibility Brand Model Series Part Number Configuration Sealand Traveler 385316906 Without hand sprayer hookup Dometic Traveler 385316906 Without hand sprayer hookup Important: This kit is for Traveler models WITHOUT the hand sprayer. If your toilet has a hand sprayer attachment, you need kit 385230325 instead (available in our store). Common Symptoms This Kit Fixes Water leaking from the back of the toilet onto the bathroom floor Water slowly filling the bowl when the toilet is not in use Weak or inconsistent flush performance Water hammer or chattering noise during flush cycle Water backing up or gurgling in the bowl after flushing Why Fix Instead of Replace? A new Sealand Traveler toilet costs $400-700. This vacuum breaker kit addresses the most common failure point for under $25. The Traveler series is known for durable ceramic bowls and robust pedal mechanisms — the vacuum breaker is typically the first and only component that fails. Replacing it restores full function and extends your toilet's life by years. This is the same repair a mobile RV tech would perform, and you can do it yourself in under an hour. Frequently Asked Questions Q: How do I know if my Traveler toilet needs this part vs the 385230325 kit?A: Check if your toilet has a hand sprayer attachment (a small hose coming from the back of the toilet with a spray nozzle). If NO sprayer → order this 385316906 kit. If YES sprayer → order our 385230325 kit. The vacuum breaker design is different for each configuration. Q: Can I install this myself, or do I need a mobile RV tech?A: Most RV owners can install this kit themselves. You'll need basic tools: Phillips screwdriver, adjustable wrench, and possibly needle-nose pliers for small o-rings. Turn off the water pump and relieve pressure before starting. Allow 30-45 minutes for first-time installation. Q: Will this stop my toilet from running intermittently?A: If your toilet's water valve cycles on and off while not in use, the vacuum breaker seal is likely the culprit. Replacing it with this kit typically resolves intermittent cycling. If the issue persists after installation, the water valve itself may need replacement. Q: Are these genuine Sealand parts?A: This is an OEM-grade aftermarket kit manufactured to Sealand/Dometic specifications. The materials, dimensions, and tolerances match the original parts. It's functionally identical to the OEM kit at a more accessible price point. Q: How often should the vacuum breaker be replaced?A: There's no fixed replacement interval — replace it when symptoms appear (leaking, backflow, weak flush). In full-time RV use, expect 3-5 years from a vacuum breaker. In occasional/seasonal use, they can last 5-8 years. 📚 Related Guides & Articles RV Toilet Maintenance: Fixing Leaks and Odors Sealand vs Dometic: RV Toilet Parts Compatibility Guide

The QR25DE engine is reliable — but its valve cover gasket is a known wear item. As the gasket hardens from heat cycling, oil seeps onto the exhaust manifold (causing a burning smell) and into spark plug wells (causing misfires). Our iFJF replacement cover solves this at a fraction of the dealer price. Installation Tips Disconnect battery before starting work. Remove ignition coils and PCV hose for access. Clean mating surface thoroughly with brake cleaner. Torque bolts to 74 in-lbs (8.4 Nm) in spiral pattern from center. Budget 45-90 minutes for DIY — straightforward bolt-on replacement. Frequently Asked Questions Q: Will this fit my 2009 Nissan Altima 2.5L?A: Yes. Direct fit for all 2007-2013 Altima with the 2.5L L4 QR25DE engine. Q: Does this fit the 2002-2006 Altima?A: No. The 2002-2006 QR25DE uses a different valve cover design (see our FJ-EVC07 listing). This cover is for 2007+ models. Q: Is the gasket included?A: Yes. The valve cover comes with a pre-installed molded rubber gasket. Q: What are signs of a bad valve cover?A: Burning oil smell from engine bay, visible oil seepage at cover edges, oil in spark plug wells, and check engine codes for misfires. Q: DIY difficulty?A: Beginner-friendly. Basic hand tools required. Budget 45-90 minutes. Q: OEM comparison?A: Matches OEM specifications (13264-JA00A/13270-JA00A) for fit and material quality at significant savings.

Product Overview Stop bowl water loss and sewer odors with this upgraded Teflon-faced toilet seal kit for Dometic Sealand VacuFlush toilets. Designed for models 110, 111, 210, and 510 — common in higher-end RVs, boats, and marine applications — this kit replaces both the 385311462 and 385310677 seal assemblies. The Teflon-faced polymer disk with raised alignment groove outperforms standard rubber seals, maintaining its shape through thousands of flush cycles and creating an odor-tight seal that lasts significantly longer. Key Features Upgraded Teflon-Faced Disk — Unlike standard rubber seals that develop compression set (permanent flattening), the Teflon surface resists deformation through thousands of flush cycles, maintaining a consistent seal. Raised Alignment Groove — Precision-molded groove centers the seal on the VacuFlush ball valve for even wear distribution and consistent sealing pressure around the entire circumference. Complete Seal Kit — Includes Teflon-faced seal disk, mounting ring, O-rings, and silicone lubricant packet — no additional parts needed for a complete rebuild. Direct OEM Replacement — Exact replacement for Dometic/Sealand part numbers 385311462 and 385310677. Same dimensions, same fit, upgraded material. Marine & RV Compatible — Works in both recreational vehicle and marine (boat/yacht) installations with VacuFlush toilet systems. Compatibility / Fitment Brand Series Models Replaces Part # Dometic / Sealand VacuFlush 110, 111, 210, 510 385311462, 385310677 Technical Specifications Specification Value Part Numbers 385311462, 385310677 Seal Material Teflon-Faced Polymer Disk Kit Contents Seal Disk, Mounting Ring, O-Rings, Silicone Lube Compatible Flush Type VacuFlush (Vacuum Flush) Installation Time 30-45 Minutes Why Choose This VacuFlush toilets are premium systems — and their seals demand premium materials. Standard rubber seals on these toilets often fail within 1-2 years, letting bowl water drain into the holding tank (creating sewer gas path) and allowing odors to enter the living space. The Teflon-faced design in this kit addresses both failure modes: it maintains its shape (no compression set) and creates a superior gas-tight barrier. Marine boat owners especially benefit, as salt air accelerates rubber degradation significantly.

The 510 series (including 510 Plus) uses this exact seal kit. The seal interface is common across all 110, 111, 210, and 510 VacuFlush toilet models from Dometic/Sealand. Q: How is Teflon better than the standard rubber seal?A: Teflon-faced seals resist compression set — the permanent flattening that causes rubber seals to lose their shape. This means a consistent seal over many more flush cycles. Teflon also has a lower coefficient of friction, reducing wear on the flush ball surface. Q: Why is my toilet bowl water dropping within hours?A: When the VacuFlush seal fails, water slowly drains from the bowl into the holding tank. This also creates an open path for sewer gases to enter the bathroom. Replace the seal to fix both issues simultaneously. Q: How often should I replace the VacuFlush seals?A: Under normal RV use, every 2-3 years. In marine (saltwater) environments or full-time liveaboard use, every 1-2 years. Replace sooner if you notice the bowl losing water or detect sewer odors. Q: Does this kit include the silicone lubricant?A: Yes. A packet of silicone lubricant is included. Apply lightly to the Teflon seal surface during installation — this helps the seal bed in and ensures smooth flush ball operation from day one. Q: Can I install this myself or do I need a tech?A: DIY-friendly with basic mechanical skills. Budget 30-45 minutes. Key steps: shut off water, flush to empty bowl, remove toilet from flange, replace seal components, reassemble, test with 4-5 flushes. Order with Confidence Fast shipping from our US warehouse.

R12T Fuel Filter Water Separator — Complete Combo Kit (10 Micron, 15 GPH) Product Overview R12T Fuel Filter Water Separator Combo Kit — 10 Micron Spin-On Filter, Replaces Racor S3240 & 120AT. Fits NPT ZG1/4-19 Outboard Motors for Gas & Diesel Engines. Complete all-in-one kit includes aluminum filter head, 10-micron filter element, clear water collection bowl, 4 brass fittings, and 2 port plugs — everything you need for a professional installation. Engineered to replace the widely-used Racor S3240 and 120AT series fuel water separators, this kit removes both solid contaminants and emulsified water from your fuel system. The 10-micron filtration media captures fine particles that can damage injectors and high-pressure pumps, while the clear collection bowl lets you visually inspect for water accumulation at a glance. With a flow rate of 15 gallons per hour, it handles engines from small marine outboards up to mid-size diesel powerplants. Key Features Complete All-in-One Kit: Filter head, spin-on element, water bowl, four fittings, and two plugs — no separate purchases needed. 10-Micron Filtration: High-efficiency cellulose media captures 99% of particles ≥10 microns, protecting injectors and fuel pumps from abrasive wear. Clear Visual Water Detection: Transparent nylon bowl with drain valve allows instant water level inspection and easy draining without disassembly. Racor S3240 / 120AT Compatible: Direct replacement for the most popular marine and industrial fuel water separator series on the market. Corrosion-Resistant Construction: Anodized aluminum filter head resists salt spray, diesel fuel, and biodiesel blends. 15 GPH Flow Rate: Supports engines up to approximately 150 HP in continuous operation.

Apply 2-3 wraps of PTFE thread sealant tape on all NPT fittings — do not overtighten. Prime the filter element with clean diesel before first start to prevent air lock. Drain the water bowl monthly or whenever water is visible in the collection chamber. Replace the filter element every 100 engine hours or annually, whichever comes first. Frequently Asked Questions Q: Will this fit my Mercury outboard fuel system?A: Yes. The R12T uses standard NPT ZG1/4-19 ports compatible with Mercury, Yamaha, and Suzuki outboard fuel line fittings from 4 HP to 200 HP. The kit includes four brass adapters for flexible installation. Q: Is this a direct replacement for Racor S3240?A: Absolutely. The thread pattern and mounting dimensions are identical to the Racor S3240 / 120AT series. You can swap your existing element and bowl, or use the complete iFJF kit for a full refresh. Q: How do I know when to drain the water bowl?A: The clear nylon bowl allows visual water inspection. If you see a visible water layer or the red indicator ring floats up, open the bottom drain valve to purge. Check before every trip. Q: Can I use this for gasoline engines?A: Yes — compatible with both gasoline and diesel. For gasoline applications, drain the bowl more frequently as ethanol-blended fuels can attract moisture. Q: What replacement filter elements fit?A: Any 120AT-style spin-on filter element with the correct thread pattern. iFJF sells replacement R12T elements individually on our store. 📊 Independent Tear-Down: iFJF R12T vs Genuine Racor Third-party visual comparison — filter head, element, and canister cut open side by side Filter Head: Visually identical to genuine Racor — no notable differences found Filter Element: ~23 inches longer than OEM — more filtration media inside Canister Wall: Thicker than genuine Racor (20mm) Complete Kit: Includes 2 brass fittings, 2 port plugs, and PTFE tape — everything needed to install 📦 Related Products & Guides 🛒 Complete Your Fuel System: R12T Replacement Filter Element ($17.99) — Spare 10-micron spin-on cartridge R12T Filter Base / Head Only ($17.99) — Just need the aluminum head + fittings?

Product Overview The iFJF Engine Valve Cover is a direct OEM-spec replacement for the 2.5L L4 QR25DE engine in 2002-2006 Nissan Altima and Sentra SE-R. This is the early-generation QR25DE cover (13264-3Z001 / 264-982), distinct from the 2007+ version. Manufactured from reinforced polymer with a pre-installed rubber gasket for leak-free sealing at a fraction of dealer cost. Key Features Early QR25DE Design: Specifically engineered for the 2002-2006 QR25DE engine — different bolt pattern and PCV layout from the 2007+ version. Verify your year before ordering. Pre-Installed Gasket: Factory-installed molded rubber gasket ensures perfect seal alignment out of the box. Heat & Oil Resistant Polymer: Reinforced construction rated for the high under-hood temperatures of daily-driven Nissan vehicles. Direct Bolt-On Fit: All mounting points and hose connections match the factory configuration exactly — no modifications needed. QC Inspected: Every cover undergoes inspection for gasket seating, surface flatness, and port alignment. Compatibility Table Year Make Model Engine 2002-2006 Nissan Altima 2.5L L4 QR25DE 2002-2006 Nissan Sentra SE-R 2.5L L4 QR25DE Specifications Specification Detail Part Number FJ-EVC07 OEM Numbers 13264-3Z001, 264-982 Material Reinforced Heat-Resistant Polymer Gasket Pre-Installed Molded Rubber Engine Nissan QR25DE 2.5L L4 (2002-2006) Installation Direct Bolt-On Warranty 12-Month Warranty Why Choose iFJF? The early QR25DE engines (2002-2006) are known for valve cover gasket degradation leading to oil leaks, pre-cat contamination, and misfire issues. Our iFJF cover provides OE-quality fit and sealing at significant savings. Important: This is for 2002-2006 models only — the 2007+ QR25DE uses a different design (see FJ-EVC02). Installation Tips Disconnect battery and remove ignition coils. Disconnect PCV hose and breather tube. Clean mating surface with brake cleaner and plastic scraper. Torque bolts to 74 in-lbs (8.4 Nm) in spiral pattern. Budget 45-90 minutes — straightforward bolt-on replacement. Frequently Asked Questions Q: Will this fit my 2005 Nissan Altima 2.5L?A: Yes. Direct fit for all 2002-2006 Altima with the 2.5L L4 QR25DE engine. Q: Does this fit 2007+ Altima?A: No. The 2007+ QR25DE uses a different valve cover design (see our FJ-EVC02 listing). This cover is specific to 2002-2006 models. Q: Is the gasket included?A: Yes. Factory-installed molded rubber gasket is pre-installed. Q: What are symptoms of a leaking valve cover?A: Burning oil smell (oil dripping on exhaust manifold), visible oil at cover edges, oil in spark plug wells, and misfire-related check engine codes. Q: DIY difficulty?A: Beginner-friendly. Basic metric socket set and torque wrench needed. Budget 45-90 minutes. Q: OEM comparison?A: Meets the same fitment and material specs as OEM 13264-3Z001/264-982 — at significant savings.
