K&N Diesel Fuel Filter for Dodge Ram 6.7L Cummins (2011–2020) PF-4801 — High-Efficiency Pleated Media, Direct-Fit

The K&N PF-4801 diesel fuel filter is a direct-fit replacement for 2011–2020 Dodge Ram 6.7L Cummins engines that delivers high-efficiency filtration and consistent fuel flow to protect injection components.

Built to meet or exceed OEM specifications, the K&N PF-4801 combines pleated cellulose-glass media with durable construction to trap contaminants while maintaining the flow modern diesel engines require. Designed specifically for the 6.7L Cummins application, this filter helps keep fuel injectors, pumps, and intake systems cleaner by removing particles and debris that accelerate wear. The cartridge snaps into existing housings for a quick swap, and its media balance emphasizes both capture efficiency and service life.

How does this fuel filter improve engine reliability?

By capturing dirt, rust, and particulates before they reach the high-pressure components, the PF-4801 lowers the risk of injector clogging and premature wear. Cleaner fuel reduces the frequency of fuel-system service and helps maintain consistent engine operation under load.

• High-efficiency pleated cellulose-glass media traps fine contaminants
• Engineered flow rate preserves fuel delivery to the pump and injectors
• Reduces debris-related deposits in fuel rails and injectors
