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

Built to replace the factory element on 2017–2026 Ford F-Series trucks with the 6.7L PowerStroke diesel, the K&N PF-4900 uses premium pleated media to capture particulates and debris without choking fuel delivery. This filter is intended as a straightforward service item that fits OEM locations and connectors, offering a balance of filtration efficiency and flow performance for heavy-duty work trucks and road use.

How does this filter maintain reliable fuel delivery under load?

The PF-4900 is engineered to provide consistent flow even when the engine demands high volumes of diesel. Its media resists excessive restriction, helping preserve injection system responsiveness during towing, hauling, or extended idling.

• High-flow pleated cellulose-glass media reduces pressure drop.
• Media layout encourages uniform fuel passage to avoid channeling.
• Designed to meet or surpass OEM flow specifications for 6.7L PowerStroke systems.

What protection does it offer for injectors and valves?

By capturing small particles and sediment before they reach the injection system, the PF-4900 helps lower the risk of abrasive wear and injector clogging. Cleaner fuel means more consistent spray patterns and fewer service interruptions related to contamination.

• Pleated media traps microscopic debris and rust particles.
• Reduces the amount of solids reaching injectors and intake components.
• Helps extend intervals for downstream component maintenance.

Is this a direct replacement for the factory fuel filter on my Ford?

The PF-4900 is produced to match the fit, form, and function of the OEM 6.7 PowerStroke filter, enabling a direct swap without modifications. Installation follows standard service procedures and uses the original mounting and connections.

• Direct-fit design for 2017–2026 Ford F250, F350, F450, F550 and compatible Super Duty models.
• Engineered to align with OEM sealing and mounting points for straightforward replacement.
• No special tools or adapters required when replacing the factory element.

How long can I expect this filter to last, and when should I replace it?

Service life depends on driving conditions and fuel quality, but the PF-4900 uses durable media intended for extended service intervals compared with lower-grade elements. Regular inspection at recommended maintenance intervals ensures optimal protection.

• Long-life media designed to hold more contaminants before restriction occurs.
• Replace according to your truck’s service schedule or whenever restriction indicators appear.
• Changing the filter along with routine fuel system checks helps protect fuel injectors and pumps.

Who is this for? The K&N PF-4900 is aimed at owners and fleets operating Ford Super Duty trucks with the 6.7L PowerStroke who want a high-quality, direct-replacement fuel filter. It suits professional technicians, owner-operators who perform their own maintenance, and anyone who needs dependable filtration to support towing, heavy use, or long service life on demanding diesel applications.
