K&N Diesel Fuel Filter for 6.7L Power Stroke Ford F-Series (2017–2026) — PF-4900 High-Flow Pleated Media

K&N PF-4900 is a premium replacement diesel fuel filter engineered to protect 6.7L Power Stroke engines by keeping contaminants out of the fuel system while maintaining high flow.

When you depend on a Ford Super Duty truck for work or towing, fuel system cleanliness matters. The K&N PF-4900 diesel fuel filter is designed as a direct-fit replacement for 2017–2026 6.7L Power Stroke trucks, offering high-efficiency media and consistent flow to help preserve injectors, valves, and other fuel-system components without restricting performance.

How does this filter maintain steady fuel delivery for heavy-duty use?

The PF-4900 uses a pleated cellulose-glass media that balances trapping efficiency with low resistance to flow. That design helps the engine receive a reliable fuel supply under load and during long haul operation, reducing the risk of flow-related performance dips.

• Pleated media for high contaminant capacity and flow.
• Engineered to match OEM fit and flow characteristics.
• Consistent delivery during idling, towing, and sustained high RPMs.

What protection does K&N’s filtration provide for my fuel system?

The filter removes particulates and debris that can wear injectors, clog ports, and increase maintenance needs. By capturing contaminants before they reach sensitive components, it helps reduce build-up and preserves the fuel system’s functional life.

• High-efficiency pleated cellulose-glass filtering material.
• Designed to catch fine particulates common in diesel fuel.
• Helps prevent premature injector and valve wear.

Is the PF-4900 an easy direct replacement for my Ford truck?

Yes—the PF-4900 is manufactured to meet or exceed OEM specifications for the 6.7L Power Stroke fuel filter. It installs in the same mounting location and uses the same connections, so routine filter changes are straightforward for mechanics and experienced DIYers alike.

• Direct replacement for specified 2017–2026 Ford F-Series models.
• No modifications required for installation.
• Fits factory mounting points and fuel lines for a snug, leak-free fit.

How long can I expect this filter to perform well between changes?

Service interval depends on operating conditions and fuel quality, but K&N’s high-capacity media is designed for extended life compared with lower-grade elements. Regular inspection and replacement per vehicle manufacturer guidance ensures continued protection and optimal fuel flow.

• High-capacity media reduces frequency of premature clogging.
• Performance longevity improves under normal fuel and service conditions.
• Follow Ford-recommended intervals and monitor for fuel-system issues.

Who this is for: The K&N PF-4900 is aimed at owners of 2017–2026 Ford F250, F350, F450, F550, F600, F650, and F750 trucks equipped with the 6.7L Power Stroke diesel who want a high-quality, OEM-compatible fuel filter. It’s suitable for fleet managers, commercial operators, and owners who tow or haul regularly and need reliable fuel-system protection without sacrificing flow.
