Product Overview The 5-Micron Fuel Filter Conversion Kit for 2011-2020 Ford 6.7L Powerstroke delivers professional-grade fuel filtration for diesel engines. Manufactured with advanced synthetic media for superior contaminant capture and water separation, this filter protects your high-pressure common rail injection system from the microscopic particles and moisture that cause premature injector and pump failure. As diesel injection pressures climb past 30,000 PSI in modern engines, fuel cleanliness has never been more critical. A single tank of contaminated fuel can cause thousands in injector damage. This filter provides the first and most important line of defense for your fuel system. Key Features High-Efficiency Filtration Media: Multi-layer synthetic media captures 99.9% of particles at the rated micron level, exceeding standard cellulose elements in both efficiency and dirt-holding capacity. Advanced Water Separation: Coalescing technology removes emulsified and free water from diesel fuel, preventing injector tip erosion and microbial growth. OEM-Spec Construction: Manufactured to ISO 9001 quality standards with precision-threaded base plate, anti-drain back valve, and high-burst-strength canister. Direct Fit Replacement: Engineered as a drop-in replacement — no modifications, adapters, or special tools required. Extended Service Life: Higher dirt-holding capacity means longer intervals between changes, reducing downtime and per-mile filtration costs. Compatibility Specification Detail Vehicle Ford F-250/F-350/F-450/F-550 Super Duty Engine 6.7L Powerstroke V8 Turbo Diesel Year Range 2011-2020 Replaces Part # BF7967, 33393 Micron Rating 2-10 Micron Absolute Filter Type Spin-On with Water Separation Why Upgrade Your Fuel Filtration? Extended Injector Life: Injectors operating at 30,000+ PSI have micron-level clearances. Better filtration means injectors lasting 200K+ miles instead of failing at 100K. Improved Cold-Weather Reliability: Superior water separation prevents ice crystal formation in fuel lines during winter. Reduced Maintenance Costs: Preventing one HPFP failure saves $5,000-$10,000 — the cost of a lifetime of premium filters. Better Fuel Economy: Clean injectors atomize fuel more efficiently, maintaining optimal combustion over the vehicle lifetime. Installation Guide Safety First: Park on level ground, engage parking brake, allow engine to cool. Have a drain pan ready. Relieve Fuel Pressure: Remove fuel cap. On some models, pull fuel pump fuse and crank briefly. Remove Old Filter: Use oil filter wrench to loosen. Unscrew by hand and lower into drain pan. Prep New Filter: Apply thin film of clean diesel to gasket. Pre-fill if housing design allows. Install: Spin on by hand until gasket contacts. Tighten 3/4 to 1 full turn. DO NOT over-tighten with wrench. Prime System: Cycle key ON (not START) 5-6 times for 30 seconds each to purge air. Check for leaks. Start & Verify: Start engine, check for leaks at idle, let run 2 minutes, recheck. Dispose of old filter properly. Frequently Asked Questions Q: Will this void my Ford warranty?A: No. Under the Magnuson-Moss Warranty Act, Ford cannot void warranty for aftermarket parts unless they prove the part caused failure. This filter meets or exceeds all OEM specifications. Many dealers install these kits. Q: What is the benefit of 5-micron vs 10-micron?A: 5-micron captures particles half the size of factory 10-micron. The Bosch CP4.2 high-pressure fuel pump in the 6.7L has extremely tight internal clearances sensitive to contamination. 5-micron = 2x better injector and pump protection. Q: Is this a complete kit?A: Yes. Includes: billet aluminum filter housing (replaces plastic OEM lower), 5-micron fuel filter element, O-ring seals, and installation instructions. Uses existing mounting bracket and fuel line connections. 30-45 minute install. Q: Do I need to tune or reprogram?A: No tuning required. Mechanical bolt-on upgrade that works with stock ECM calibration. Fuel flow rates remain within factory parameters. Simply prime system by cycling key 5-6 times before starting to purge air.

Product Overview The Ford 7.3L Powerstroke Fuel Filter (1995-1998) — FD-4595 from iFJF is a precision-engineered aftermarket upgrade designed to deliver exceptional performance, durability, and value. Engineered to meet or exceed OEM specifications, this filtration component provides superior contaminant removal and flow characteristics. Built with high-quality media and precision-manufactured housing for a guaranteed direct fit on your vehicle. Vehicle Compatibility This product is designed for the following vehicles: 1995-1998 F-250, F-350 7.3L Powerstroke; 1995-1998 E-350 7.3L Service Interval Every 15,000 miles OBS Powerstroke: The DIY-Friendly Generation The OBS 7.3L is beloved for its simplicity. The fuel filter sits in an easily accessible fuel bowl on top of the engine. No crawling under the truck, no special tools — open the hood, unscrew the cap, swap the filter, done in 10 minutes. FAQ Q: My OBS Powerstroke dies randomly — could it be the fuel filter? A: The #1 cause of random stalling on OBS 7.3Ls is the Cam Position Sensor (CPS) , not the fuel filter. But a clogged filter can cause low-power complaints that feel similar. CPS failure = sudden stall, no restart until cool. Clogged filter = low power, possible stall under load. Q: Do I need to fill the fuel bowl after changing the filter? A: Yes. After installing the new filter and cap, fill the fuel bowl with clean diesel fuel before starting. This prevents extended cranking. Some owners also cycle the key 3-4 times to activate the fuel pump before starting. Note: Professional installation is recommended. Verify fitment for your specific sub-model, cab configuration, and drivetrain (2WD/4WD) before ordering.

FD-4625 Fuel Filter Element for 2017-2019 Ford 6.7L Powerstroke — OEM-Grade Replacement The FD-4625 Fuel Filter Element is the direct OEM replacement for 2017, 2018, and 2019 Ford 6.7L Powerstroke diesel engines. This cartridge-style drop-in filter replaces Motorcraft FD-4625 (HC3Z-9N184-B & HC3Z-9N184-C) with equivalent 10-micron filtration performance at a fraction of dealer pricing. Precision-engineered for the second-generation 6.7L fuel system, this filter protects your high-pressure CP4.2 injection pump from water and particulate contamination. Second-Gen 6.7L Fuel System: What Changed in 2017 For the 2017 model year, Ford redesigned the 6.7L Powerstroke fuel filter housing from the earlier spin-on design (FD-4615) to a cartridge-style system. The FD-4625 drops into a permanent canister mounted on the driver-side frame rail, using a replaceable element instead of a disposable canister. This design improves serviceability and reduces waste — but it also means you cannot use 2011-2016 spin-on filters in a 2017+ truck. Make sure you're ordering the correct filter type. Key Features 10-Micron Filtration: Captures 99% of particles at 10 microns, matching OEM HC3Z-9N184-B specifications for reliable CP4.2 pump protection. Exact OEM Fit: Precision-molded end caps and O-ring grooves ensure a leak-free seal inside the factory filter housing — no modifications needed. Complete Kit: Includes filter element + replacement housing O-ring. Everything you need for a standard service. IATF 16949 Certified: Manufactured under automotive quality management standards, delivering OEM-equivalent reliability at aftermarket pricing. Extended Service Life: Rated for 22,500-mile service intervals under normal driving conditions (15,000 miles for severe duty/towing). Compatibility / Fitment Year Make Model Engine 2017-2019 Ford F-250 Super Duty 6.7L Powerstroke V8 Diesel 2017-2019 Ford F-350 Super Duty 6.7L Powerstroke V8 Diesel 2017-2019 Ford F-450 Super Duty 6.7L Powerstroke V8 Diesel 2017-2019 Ford F-550 Super Duty 6.7L Powerstroke V8 Diesel Not compatible with 2011-2016 6.7L (uses FD-4615 spin-on) or 2020+ 6.7L (uses FD-4631). Technical Specifications Part Number FD-4625 OEM Cross-Reference HC3Z-9N184-B, HC3Z-9N184-C, Motorcraft FD-4625 Superseded From FD-4624 (improved media in FD-4625 — backward compatible) Filter Type Cartridge Element (drop-in) Filtration Rating 10 Micron Nominal Service Interval 22,500 miles (every 3rd oil change) — 15,000 miles severe duty Installation Location Driver-side frame rail, under driver door area Housing Cap Torque 25 Nm (18 ft-lbs) ⚠️ Before You Start: The fuel filter return line connector (HC3Z-9A564-A) on 2017+ 6.7L Powerstroke models is a known failure point. If your truck cranks excessively before firing, replace this $15 connector alongside your filter — we stock it separately. Installation Steps Locate fuel filter housing on driver-side frame rail, just behind the front wheel Drain water from the separator using the 6mm hex drain plug — catch fuel in a container Unscrew the housing cap using a 36mm socket — do NOT use a strap wrench (may crack the cap) Remove old cartridge element — note the orientation before pulling it out Install the new FD-4625 element — it only seats correctly in one direction Replace the housing O-ring with the new one included in this kit Reinstall cap and torque to 25 Nm (18 ft-lbs) Cycle ignition to ON (do NOT start) for 30 seconds, then OFF — repeat 6-8 times to prime the system Start engine and inspect for leaks at the cap and drain plug Why Choose iFJF FD-4625 Over OEM? Same 10-Micron Protection — No compromise on filtration. Your CP4.2 pump is too expensive to gamble on cheap filters. 50-60% Less Than Dealer Pricing — Motorcraft FD-4625 runs $60-80 at Ford dealers. Get the same protection for less. Coast-to-Coast US Inventory — Ships from US warehouses. No 2-week AliExpress wait times. 12-Month Warranty — Every iFJF filter is backed by our hassle-free replacement guarantee. Frequently Asked Questions Q: FD-4625 vs. FD-4624 — what's the difference and which one do I need? A: FD-4624 was the original part number when the second-gen 6.7L launched in 2017. Motorcraft superseded it with FD-4625, which uses improved filtration media for better water separation and longer service life. FD-4625 is 100% backward-compatible with all 2017-2019 applications. If you're seeing FD-4624 referenced, the FD-4625 in this listing is the correct current replacement. Q: Will this fit my 2017/2018/2019 F-250 or F-350? A: Yes — the FD-4625 fits all 2017, 2018, and 2019 Ford F-250, F-350, F-450, and F-550 Super Duty trucks with the 6.7L Powerstroke V8 diesel engine. It does NOT fit 2011-2016 models (they use spin-on FD-4615) or 2020+ models (they use FD-4631). Always confirm your model year before ordering. Q: How often should I replace the fuel filter on my 6.7L Powerstroke? A: Ford recommends every 22,500 miles (typically every 3rd oil change at 7,500-mile intervals). If you tow heavy, idle frequently, run biodiesel blends above B5, or operate in dusty conditions, replace every 15,000 miles. Always drain the water separator at every oil change regardless of mileage. Q: Why is my 2017+ 6.7L hard to start after sitting overnight? A: The #1 cause is a cracked fuel return line connector (HC3Z-9A564-A) allowing air into the system and fuel to drain back to the tank. Replace this $15 plastic connector before replacing injectors or high-pressure pumps. Second most common cause: a worn housing cap O-ring letting air in — always replace the O-ring with every filter change. Q: Can I reuse the old O-ring if it looks fine? A: No. The housing cap O-ring is a one-time-use seal. Even if it looks fine, heat cycling causes micro-compression that prevents a proper seal on reinstallation. A leaking O-ring can cause extended cranking, rough idle, and eventual CP4.2 damage from air in the fuel system. Every FD-4625 kit includes a new O-ring — use it. Q: What tools do I need to change this filter? A: A 36mm socket (or 1-7/16" SAE) for the housing cap, a 6mm hex key (Allen wrench) for the drain plug, a drain pan to catch fuel, and shop rags. No special tools required. Most DIYers complete the job in 20-30 minutes.

Ford 6.7L Powerstroke 5-Micron Fuel Water Separator FD-4615 — Superior CP4.2 Protection The FD-4615 5-Micron Fuel Water Separator provides twice the filtration of the factory 10-micron filter for 2011-2016 Ford 6.7L Powerstroke engines. If you're protecting your Bosch CP4.2 high-pressure fuel pump — and you absolutely should be — this 5-micron upgrade is the single most important maintenance decision you'll make. Compatibility Make Model Years Engine Ford F-250 Super Duty 2011-2016 6.7L Powerstroke V8 Turbo Diesel Ford F-350 Super Duty 2011-2016 6.7L Powerstroke V8 Turbo Diesel Ford F-450 Super Duty 2011-2016 6.7L Powerstroke V8 Turbo Diesel Ford F-550 Super Duty 2011-2016 6.7L Powerstroke V8 Turbo Diesel Key Features 5-Micron Absolute Filtration: Catches particles half the size that the factory BC3Z-9N184-B 10-micron filter passes through. The CP4.2 pump's internal clearances are measured in single-digit microns — every 5-micron particle stopped is one that won't score your pump's precision-machined internals. Advanced Water Separation: Multi-layer media with hydrophobic barrier removes both free and emulsified water from diesel fuel — the #1 cause of CP4.2 corrosion and seizure. High-Flow Design: Engineered for full fuel volume under all operating conditions, including WOT towing at maximum GVWR. No restriction, no performance loss. Extended Dirt-Holding Capacity: Greater media surface area means longer service life despite finer filtration. Same 15,000-22,500 mile interval as the factory filter. Direct Factory Replacement: Fits the factory plastic fuel filter housing — no adapters, no modifications, no special tools. Technical Specifications Part Number FD-4615 OEM Cross-Reference BC3Z-9N184-B (factory replacement, upgraded filtration) Filtration Rating 5 Micron Absolute (factory: 10 micron) Filter Type Cartridge-style fuel water separator Service Interval Every 15,000-22,500 miles or 12 months Housing Fitment Factory plastic housing (frame-mounted). Also compatible with iFJF 121003 All-Metal Conversion Kit 5-Micron vs 10-Micron — Why It Matters The factory 10-micron filter stops particles the size of a red blood cell. The FD-4615 stops particles half that size. The Bosch CP4.2 high-pressure fuel pump generates 29,000+ psi and relies on diesel fuel for both cooling and lubrication. Internal clearances between the pump's roller tappets, cam lobes, and housing are measured in microns. A single particle that passes through a 10-micron filter can initiate the scoring cascade that eventually destroys the pump — sending metal debris through all 8 injectors, both fuel rails, and the entire high-pressure system. Complete repair: $8,000-$12,000. Installation Guide Locate Filter Housing: Frame-mounted on the driver side, under the vehicle near the fuel tank. Drain Water Separator: Open the drain valve and collect any water/fuel in a suitable container. Remove Housing Cap: Use the appropriate filter wrench. Do not use pliers or channel locks — you'll crack the plastic housing. Replace Cartridge: Remove old filter, clean housing interior, insert new FD-4615 with fresh O-ring. Tighten to Spec: Hand-tighten, then 1/4 turn with wrench. Over-tightening cracks the plastic housing. Prime System: Cycle ignition ON (do not start) for 30 seconds, 3-4 times, to refill the filter housing. Check for Leaks: Start engine, let idle for 2 minutes, inspect for fuel leaks at the housing cap. FAQ Q: Will 5-micron filtration restrict fuel flow? A: No. The FD-4615 uses high-flow media engineered specifically to maintain full fuel volume at 5-micron absolute. Your CP4.2 receives the same fuel flow as with the factory filter — just cleaner fuel. Q: Do I need to change 5-micron filters more often? A: No. The greater surface area and dirt-holding capacity of the FD-4615 maintains the standard 15,000-22,500 mile service interval despite the finer filtration rating. Q: Can I combine this with fuel additives? A: Absolutely — and you should. Fuel additives improve lubricity and cetane but don't filter solid particles. The FD-4615's 5-micron filtration and a quality fuel additive are complementary protection strategies. Q: Is this worth it if I already have the factory filter? A: The factory 10-micron filter is adequate for warranty coverage — it is not optimal for long-term CP4.2 survival. For less than the cost of a tank of diesel, you get twice the protection for a $8,000-$12,000 fuel system. The math is straightforward. Why Choose iFJF?

Secondary is on the engine near the HPFP. Drain Water Separator: Use the drain valve on the primary housing to empty accumulated water before opening. Remove Old Cartridges: Unscrew housing caps, remove old filters, discard old O-rings. Install New O-Rings: Lubricate new O-rings with clean diesel fuel and seat them in the cap grooves. Insert New Filters: Place FD-4617 cartridges into housings, tighten caps to spec. Prime System: Cycle key to ON position 3-4 times (30 seconds each) to refill filter housings. Do NOT crank until the fuel system is primed. FAQ Q: How many FD-4617 filters does my 6.4L need? A: Two. Both the frame-mounted primary and engine-mounted secondary housings use the identical FD-4617 cartridge. Always replace both at the same service interval. Q: Why change 6.4L filters every 10K miles instead of 15K like the 6.7L? A: The 6.4L's DPF regeneration system injects fuel on the exhaust stroke to elevate exhaust temperatures, which circulates hotter fuel through the filter housings. Hotter fuel accelerates media degradation. The 10K interval is cheap insurance against a $3,000+ HPFP failure. Q: Are 6.4L and 6.0L fuel filters interchangeable? A: No. The 6.4L uses FD-4617 with specific thread patterns and seal dimensions. The 6.0L uses FD-4616. Using the wrong filter creates leaks and bypasses filtration entirely. Q: What happens if the HPFP fails? A: The Siemens HPFP ($3,000+ for the pump alone) sends metal debris through all 8 piezo injectors, both fuel rails, and high-pressure lines. Complete fuel system replacement typically exceeds $8,000. Prevention through quality filtration is the only cost-effective strategy. Q: Any special considerations for deleted trucks? A: Warning: EGR/DPF/Def systems must remain intact for on-road vehicles. Off-road/competition use only in applicable jurisdictions. Filter service intervals remain unchanged regardless — the HPFP still requires clean fuel for lubrication. Why Choose iFJF Filters?

Ford 7.3L Powerstroke Engine Air Filter CA9676 — Feed the Legendary GTP38 Turbo The CA9676 Engine Air Filter is the OEM-spec replacement for 1999-2003 Ford 7.3L Powerstroke Super Duty trucks and 2000-2003 Excursions. The 7.3L's Garrett GTP38 turbocharger is legendary for reliability, but it still demands clean air. A restricted filter directly impacts boost, increases exhaust gas temperatures, and reduces towing performance — the exact opposite of what you want from the million-mile motor. Compatibility Make Model Years Engine Ford F-250 Super Duty 1999-2003 7.3L Powerstroke V8 Turbo Diesel Ford F-350 Super Duty 1999-2003 7.3L Powerstroke V8 Turbo Diesel Ford F-450 Super Duty 1999-2003 7.3L Powerstroke V8 Turbo Diesel Ford F-550 Super Duty 1999-2003 7.3L Powerstroke V8 Turbo Diesel Ford Excursion 2000-2003 7.3L Powerstroke V8 Turbo Diesel Key Features GTP38 Turbo Protection: The 7.3L's Garrett GTP38 moves massive air volumes — especially with performance tuning. This filter provides unrestricted airflow while capturing dust, pollen, and debris that would otherwise blast through the compressor wheel. Factory Cold-Air Intake Routing: The OEM CA9676 filter in the factory air box routes cold air from the fender — providing cooler, denser intake air than the popular open-element 6637 mod. Better for towing and daily driving. OEM-Exact Dimensions: Manufactured to the precise dimensions of the Ford factory filter for perfect sealing. No modifications to the air box required — drops right in. Disposable Dry Media: Engineered for one-time use. The paper-based media should never be cleaned, oiled, or blown out with compressed air — doing so damages the fiber structure. Visual Inspection Ready: The simple panel design allows quick visual checks — hold the filter up to a light source. If you can't see light through the media, it's time to replace. Technical Specifications Part Number CA9676 OEM Cross-Reference 2U2Z-9601-BA, 2U2J-9601-BA, PA5689, 49090 Filter Type Panel-style dry media engine air filter Service Interval Every 30,000 miles (15,000 in off-road or dusty conditions) Recommended Check Inspect at every oil change — hold filter up to light to check media condition CA9676 vs the 6637 Mod — Which Is Right for You? The "6637 mod" is a popular 7.3L upgrade where owners replace the entire factory air box with a large cylindrical Napa 6637 filter. While this increases total airflow potential, it also introduces trade-offs: increased intake noise, potential hot engine bay air ingestion, and loss of the factory cold-air routing. The OEM CA9676 filter in the factory air box draws cold air from the fender well — cooler, denser air for better combustion efficiency. For stock to mild tuned trucks used for towing or daily driving, the factory system with a fresh CA9676 provides excellent filtration with factory-engineered cold-air routing. Installation Guide Open Air Box: Release the clips on the factory air filter housing (passenger side of engine bay). Remove Old Filter: Lift out the old CA9676 element. Inspect the housing interior for debris, oil from the CCV system, or signs of water intrusion. Clean Housing: Wipe the interior with a clean, dry cloth. Pay attention to the sealing surface. Install New Filter: Place the new CA9676 into the housing, ensuring even seating against the sealing surface. Close and Secure: Replace the cover and secure all clips. Verify no visible gaps. FAQ Q: How do I know if my 7.3L air filter needs replacing? A: Hold the filter up to a light source. If you can't see light through the media, it's clogged. Also check for debris in the pleats, oil contamination from the crankcase ventilation system, or visible damage to the seal. Replace every 30,000 miles regardless of appearance. Q: Can a dirty air filter cause my 7.3L to smoke? A: Yes — black smoke under acceleration is a classic symptom of restricted airflow. The engine runs rich because the turbo can't pull enough air through a clogged filter. Replacing the air filter typically clears the smoke immediately if no other issues are present. Q: CA9676 vs 6637 mod — which is better? A: The 6637 mod provides more airflow potential but can ingest hot engine bay air and increases intake noise. The OEM CA9676 routes cold air from the fender — better for towing and daily driving. For stock-to-mild tuned trucks, stick with the OEM-spec CA9676. Q: Is this filter compatible with aftermarket tuning? A: Yes, for mild to moderate tunes (up to approximately 60-80 HP over stock). Heavily modified trucks with larger injectors and upgraded turbos may require higher-flow aftermarket intake systems — but for most tuned 7.3Ls, the factory air box with a fresh CA9676 is fully adequate.

It costs $1,500+ to replace and requires specialized calibration equipment that most shops don't have. Water in the fuel causes internal corrosion and eventual seizure of the pumping elements. Unlike modern common-rail pumps, the DB2 cannot be remanufactured without a dedicated Stanadyne calibration bench. Quality fuel filtration is your only practical defense — and the FD3375 is engineered specifically for this duty. Installation Guide Locate Filter: The fuel water separator is mounted on the passenger-side inner fender or firewall, depending on the model year. It's a spin-on canister with a water drain at the bottom. Drain Water First: If your housing has a drain valve, drain accumulated water into a container before removing the filter. Remove Old Filter: Use a strap wrench if necessary. The spin-on design typically allows hand removal if the previous installer didn't over-tighten. Prepare New Filter: Fill the new FD3375 with clean diesel fuel (reduces cranking time for priming). Apply a thin film of diesel to the gasket. Install: Spin on by hand until the gasket contacts the mounting surface, then tighten an additional 1/2 to 3/4 turn. Do not over-tighten. Prime System: If equipped with a mechanical lift pump, crank the engine in 15-second bursts with 30-second cool-down periods until it starts. An electric lift pump upgrade (available from iFJF) makes priming effortless. FAQ Q: Can I use a 7.3L Powerstroke filter on my IDI? A: No. Despite the shared 7.3L displacement, the IDI and Powerstroke use completely different fuel systems. The IDI's mechanical DB2 injection pump requires different filtration specifications. Using a Powerstroke filter can cause inadequate filtration and catastrophic pump damage. Q: My IDI is hard to start after sitting — is the fuel filter the problem? A: Probably not. The #1 cause of hard-start-after-sitting on IDI engines is air intrusion through the return line system — the plastic return caps and O-rings on top of the injectors allow fuel to drain back to the tank. A clogged filter causes different symptoms: low power, black smoke, and poor fuel economy. Q: Should I add an electric lift pump to my IDI? A: Many IDI owners add an electric lift pump to provide positive fuel pressure to the injection pump. This improves starting, reduces air intrusion, and extends injection pump life. iFJF offers a compatible electric lift pump — contact support@ifjf.net for details. Q: Is biodiesel safe with this filter? A: Yes, for blends up to B20. For biodiesel above B20, reduce the service interval to 10,000 miles. Biodiesel has greater solvency and can release tank deposits that load the filter more quickly. Why Choose iFJF?
