The original Rochester Quadrajet was a brilliant design but suffered from warped bodies, leaky well plugs, and worn throttle shafts after decades of service. Our 1901R replacement addresses all these weaknesses with modern CNC machining, improved aluminum alloy, and precision calibration. You get the signature Quadrajet sound and performance without the headaches of a 50-year-old core. Each unit is wet-flow tested before leaving the factory. We stand behind every carburetor with our satisfaction guarantee. Installation Tips Verify intake manifold is square bore pattern (not spread bore without adapter) Set idle mixture screws to 2-1/2 turns out as starting point Use a phenolic spacer to reduce heat soak on hot starts Check fuel pressure — Quadrajets prefer 5-6 PSI maximum Connect choke cable to manual choke linkage before final mounting Torque mounting bolts to 12-15 ft-lbs in a crisscross pattern Frequently Asked Questions Q: Will this fit my 1969 Camaro with a 350?A: Yes. This 1901R Quadrajet 4MV is a direct replacement for 1966-1973 Chevy 327-454 engines with a square bore intake manifold. Your 1969 Camaro 350 is a perfect match. Q: Does this carburetor come with a gasket?A: Yes, a base gasket is included. We recommend using a quality fiber gasket or 1/4" phenolic spacer for best results. Q: Is this a rebuilt original or brand new?A: This is a 100% brand new carburetor — not a remanufactured or rebuilt core. No core charge, no waiting for a rebuild. Q: Do I need an adapter to install this on a spread bore manifold?A: This is a square bore carburetor. If your intake manifold is a spread bore (common on later Quadrajets), you will need a square-to-spread bore adapter plate (sold separately). Q: How do I adjust the manual choke?A: The choke lever connects to a standard choke cable (not included). Route the cable through your firewall and mount under the dash. Pull to close choke for cold starts, push to open as engine warms. Q: What's the difference between vacuum secondary and mechanical secondary?A: Vacuum secondaries open based on engine load — they only engage when the engine can actually use the extra air/fuel. This prevents bogging and improves driveability on the street compared to mechanical secondaries. Q: Does this carburetor have EGR provisions?A: No. This carburetor does not include EGR provisions, making it ideal for non-emissions applications, off-road use, or vehicles with EGR deleted.

1.25-Inch Pool Inlet Jet Nozzle, Hose Holder & Strainer Grid Kit The iFJF Complete Pool Inlet Kit includes everything you need to connect your filtration system to an above ground swimming pool. With the inlet jet nozzle, hose holder, and strainer grid, this kit replaces worn or missing pool inlet components in one convenient package. What's Included Inlet Jet Nozzle: Directs filtered water back into the pool with an adjustable eye for optimizing circulation patterns Hose Holder/Adapter: Secures the 1.25-inch filter hose to the pool wall fitting for a leak-free connection Strainer Grid: Prevents large debris from entering the filtration system and protects the pump impeller Key Features Standard 1.25-Inch Fitment: Compatible with most above ground pool filtration systems including Intex, Bestway, and Coleman Adjustable Jet Direction: Aim the water flow to optimize circulation and improve skimming efficiency Corrosion-Resistant Materials: UV-stabilized ABS plastic withstands pool chemicals and sun exposure Leak-Free Connection: Precision-molded threads and gasket surfaces ensure a watertight seal Easy DIY Installation: No special tools needed — typical installation takes under 15 minutes Why Replace Your Pool Inlet Fittings? Over time, pool inlet components degrade from constant exposure to chlorinated water and UV rays. A worn jet nozzle can't direct water effectively, leading to poor circulation and dead spots where algae can grow. A cracked hose holder causes leaks that reduce pump efficiency. And a missing strainer grid allows debris into your pump — potentially damaging the impeller. This kit addresses all three issues at once. Installation Steps Turn off the pool pump and close any existing valves Remove the old inlet components from the pool wall Clean the wall fitting threads with a soft brush Install the new strainer grid on the inside of the pool wall Thread the jet nozzle into the inside wall fitting Attach the hose holder to the outside wall fitting Connect your filter hose and tighten the hose clamp Open valves and restart the pump — check for leaks FAQ Q: Will this fit my Intex above ground pool?A: Yes. This 1.25-inch inlet jet kit is designed as a direct replacement for standard Intex and Bestway above ground pool filtration fittings. Q: What's included in the kit?A: The kit includes one inlet jet nozzle, one hose holder/adapter, and one strainer grid — everything for a complete inlet connection. Q: How do I know if I need 1.25" or 1.5" fittings?A: Measure the outside diameter of your existing pool hose or fitting. Most smaller above ground pools (up to 15 feet) use 1.25-inch fittings, while larger pools typically use 1.5-inch. Q: Is this compatible with saltwater systems?A: Yes, the fittings are made from corrosion-resistant ABS plastic suitable for saltwater and chlorine pools.Related Products Smart WiFi Sprinkler Controller 8-Zone — Weather Intelligent | iFJF 1.25" & 1.5" Pool Pipe Support with Plunger Valve – Above Ground Pool Fittings ( 10-Pack Brass Pool Cover Anchor Collar Beauty Rings - Universal 9/16" ID | iFJF 10747 25010 Plunger Valve Assembly w/ O-Rings for Above Ground Pool Filter Pump 11872 Dual Split Hose Plunger Valve Connector for Above Ground Pool Pump | iFJF 📚 Related Guides & Articles iFJF Product Buying Guide — How to Choose the Right Part Diesel vs. Gas Engines: Complete Maintenance Guide

Whether you're building a show car, customizing your daily driver, or adding flair to your truck, this LED exhaust tip delivers head-turning style. Key Features Blue LED Illumination: Bright, energy-efficient LED ring creates an eye-catching blue glow that activates with your parking lights or headlights. Carbon Fiber Pattern Finish: Premium 3D carbon fiber exterior resists heat, fading, and road debris — looks aggressive day or night. Universal Clamp-On Design: 2.5" inlet diameter fits most common exhaust pipe sizes. Clamp-on installation requires no welding or permanent modifications.

Q: How do I wire the LED?A: Simple two-wire connection — colored wire to tail light positive circuit, black wire to chassis ground. The LED will illuminate automatically with your parking lights or headlights. Basic 12V wiring knowledge required; professional installation recommended. Q: Will this fit my car?A: The 2.5" inlet fits most common exhaust pipe diameters. Measure your existing exhaust tip's outlet diameter before ordering. Compatible with any vehicle that has a 2.5" or smaller exhaust pipe. Q: Does the LED generate excessive heat?A: The LED ring is rated to withstand normal exhaust temperatures at the tailpipe exit. However, it should NOT be installed within 12 inches of the catalytic converter or muffler inlet where temperatures are significantly higher. Q: Is the carbon fiber real?A: The exterior features a high-quality 3D carbon fiber pattern finish on durable materials that provide the look of real carbon fiber with superior heat resistance and UV stability. Q: Will this affect my exhaust sound or performance?A: No. This is a cosmetic tip only — it does not restrict flow, alter backpressure, or change exhaust sound. It simply slides over the end of your existing exhaust pipe.

Complete Front Lower Control Arm Kit for BMW E39 525i 528i 530i The iFJF CA-0048 is a complete 2-piece front lower control arm kit designed for 1997-2003 BMW 525i, 528i, and 530i (E39 chassis) equipped with 2.5L, 2.8L, and 3.0L M52/M54 inline-6 engines. Each arm comes with the critical bushing and ball joint pre-installed, providing a direct bolt-on replacement for worn original equipment. If your E39 has developed the dreaded steering wheel shimmy, front-end clunking, or vague steering response, these control arms are the definitive solution to restore the precise, confidence-inspiring handling that BMW engineers designed into the E39 platform. Understanding the BMW E39 Front Suspension The BMW E39 is widely regarded as one of the best-driving sports sedans ever built, and its sophisticated multi-link front suspension is a key reason why. Each front corner uses two control arms: the lower control arm (wishbone) and the upper control arm (thrust arm/tension strut). The lower control arm is responsible for lateral wheel location and camber control, while its large rubber bushing absorbs road impacts and isolates vibration. The ball joint at the outer end connects the control arm to the steering knuckle, handling both vertical suspension movement and steering input forces. After 60,000-80,000 miles, the rubber bushings degrade, crack, and separate from their housings, while the ball joints develop play. The result is degraded handling, vibration, and uneven tire wear - all of which the iFJF CA-0048 kit is engineered to correct. Vehicle Compatibility Make Model Chassis Years Engine BMW 525i E39 2001-2003 2.5L M54 I6 BMW 528i E39 1997-2000 2.8L M52 I6 BMW 530i E39 2001-2003 3.0L M54 I6 Technical Specifications Specification Detail Position Front Lower (Left & Right) Material Forged Steel with Corrosion-Resistant Coating Bushing Type Hydraulic Rubber (OEM-Spec Durometer) Ball Joint Type Sealed, Greased-for-Life Ball Joint Taper OEM BMW Specification Quantity 2 Pieces (Left + Right) Installation Bolt-On Replacement - Pre-Assembled SKU CA-0048 Common Signs of Worn E39 Control Arms Steering wheel shimmy (55-65 mph): The most classic E39 symptom - vibration felt through the steering wheel that peaks around 55-60 mph and may diminish at higher speeds Clunking over bumps: A metallic knock or clunk when driving over potholes, speed bumps, or uneven road surfaces Uneven tire wear: Inner or outer edge tire wear, often with a scalloped or feathered pattern Vague or wandering steering: The car doesn't track straight and requires constant small corrections Brake shudder: Vibration through the steering wheel during moderate to hard braking Frequently Asked Questions Q: What BMW models does this control arm kit fit?A: This 2-piece front lower control arm kit fits 1997-2003 BMW 525i, 528i, and 530i (E39 chassis) with 2.5L M54, 2.8L M52, and 3.0L M54 inline-6 engines. Please verify your vehicle's chassis code and production date before ordering. Q: What are the symptoms of worn control arms on a BMW E39?A: Common symptoms include steering wheel vibration at 50-65 mph (the infamous E39 shimmy), clunking noises over bumps, uneven or scalloped tire wear, wandering steering that requires constant correction, and reduced steering precision and feedback. Q: Does this kit include both left and right control arms?A: Yes, this is a complete 2-piece kit including both left and right front lower control arms. Each arm comes with the hydraulic bushing and ball joint pre-installed and ready for installation. Q: How difficult is the installation on an E39?A: Installation requires intermediate mechanical skills and typically takes 2-4 hours. You'll need a floor jack, jack stands, basic socket set (16mm, 18mm, 21mm), torque wrench, and optionally a ball joint separator tool. A professional wheel alignment is mandatory after installation. Q: Should I replace the thrust arms at the same time?A: The E39 uses two control arms per side. If your lower control arms are worn, the thrust arm (upper control arm) bushings are likely in similar condition. We recommend replacing both as a complete front-end suspension refresh for the best results and longest service life. Q: Do I need an alignment after installation?A: Yes, a professional 4-wheel alignment is absolutely required after control arm replacement. The lower control arm directly affects camber and caster angles. Operating the vehicle without a proper alignment will cause rapid and uneven tire wear.

Factory carburetors from the 60s-80s are now 40-60 years old. They suffer from warped castings, corroded passages, worn throttle shafts, and degraded accelerator pumps. Our 1805 is brand new — no core required, no rebuilding, no surprises. The annular boosters found on the Thunder AVS are a genuine upgrade over standard boosters, providing fuel atomization comparable to fuel injection at a fraction of the cost. Each unit is wet-flow tested and pre-calibrated for out-of-the-box performance. Frequently Asked Questions Q: Will this bolt onto a stock Chevy 350 intake manifold?A: Yes — as long as your intake manifold has a square bore flange pattern. Most 1966-and-later Chevy small block intakes are square bore. If you have a spread bore manifold (e.g., some Quadrajet applications), you'll need an adapter. Q: What's included in the box?A: Carburetor, base gasket, mounting studs/nuts/washers, and installation instructions. Q: Can I use this with an automatic transmission?A: Yes. The 1805 works with both automatic and manual transmissions. You'll need to connect your transmission's kickdown linkage (TH350/TH400/700R4) using the provided throttle lever. Q: How do I hook up the manual choke?A: Route a universal choke cable (not included) from the choke lever on the carburetor, through the firewall grommet, to a dash-mounted pull knob. Most auto parts stores carry universal choke cable kits for $10-20. Q: Will this work at high altitude (5,000+ ft)?A: At high altitude, you may need to lean the mixture. The 1805 accepts standard Edelbrock/Thunder-series jets and metering rods for calibration. For altitudes above 5,000 ft, go down 1-2 jet sizes.

Product Overview Unleash your V8's full potential with the iFJF 1407 4-Barrel Carburetor. This 750 CFM performance carburetor features a manual choke, square bore design, and mechanical secondaries — the go-to setup for street performance and weekend strip runs. The striking golden finish isn't just for looks — it's a corrosion-resistant coating that protects against ethanol-blended fuels. Whether you're building a crate motor, restoring a classic muscle car, or upgrading from a tired 2-barrel, the 1407 delivers crisp throttle response and reliable fuel delivery. Key Features 750 CFM Flow: Ideal for 350-454 cubic inch V8 engines — supports up to 500+ horsepower with the right cam and intake. Manual Choke: Simple, reliable cold-start enrichment — pull the cable, fire it up, push it in when warm. No vacuum diaphragm to fail. Square Bore Design: Compatible with most aftermarket intake manifolds (Edelbrock Performer, Weiand, Holley pattern). Mechanical Secondaries: Instant throttle response — secondaries open with your right foot, not engine vacuum. Perfect for aggressive driving. Golden Dichromate Finish: Corrosion-resistant coating protects against modern ethanol-blended fuels and looks great under the hood. Air Valve Secondary: Adjustable secondary air valve tunes the transition from primary to WOT — eliminates the bog common with vacuum secondary carbs. Recommended Applications Engine Size Cam Type Usage 350-383 CID Mild to Hot Street Street / Weekend Strip 400-454 CID Stock to Mild Street Cruiser / Towing 383-454 CID Hot Street / Race Strip / Performance Street Specifications Spec Detail Model 1407 CFM Rating 750 Barrels 4 Choke Manual Bore Type Square Bore Secondaries Mechanical with Adjustable Air Valve Finish Golden Dichromate Fuel Inlet Single (3/8" NPT) Tuning Tips Set Float Levels: Adjust to the middle of the sight glass window with the engine running — too high causes rich idle, too low causes lean stumble. Idle Mixture: Start at 1.5 turns out. Adjust for highest vacuum reading, then back each screw out 1/8 turn for a slightly rich idle — smoother transition off-idle. Secondary Air Valve: Adjust the spring tension to open secondaries without bogging. Too loose = bog; too tight = secondaries never open. Start with 3/4 turn of preload. Fuel Pressure: Keep fuel pressure between 5-7 psi. Above 7 psi can overwhelm the needle and seat, causing flooding. Frequently Asked Questions Q: Will this carburetor fit my intake manifold?A: The 1407 has a square bore bolt pattern compatible with most aftermarket 4-barrel intake manifolds (Edelbrock, Weiand, Holley-square-bore). It will NOT fit a spread-bore manifold (Quadrajet pattern) without an adapter plate. Q: Is 750 CFM too much for my 350?A: A 750 CFM carb works well on a 350 with a performance cam, headers, and intake. For a bone-stock 350 with stock heads and cam, a 600-650 CFM carb would be better matched. The 1407's air valve secondaries help prevent over-carburetion by only flowing what the engine demands. Q: How is the manual choke set up?A: You'll need a manual choke cable kit (sold separately) routed to the cabin. Mount the cable under the dash, connect it to the carb's choke lever, and adjust for full open/close travel. Many hot-rodders prefer manual chokes for their simplicity and reliability. Q: Does this carb support a kickdown linkage?A: Yes — the throttle lever includes provisions for GM TH350/TH400, Ford C4/C6, and Chrysler 727 kickdown linkages. An aftermarket bracket may be needed for some applications. Q: Is this ready to run out of the box?A: The 1407 comes pre-calibrated for a typical performance V8. You'll need to set the idle speed, idle mixture, and float levels. The secondary air valve may need adjustment based on your specific engine combination.
