The K&N PF-4800 is a replacement diesel fuel filter for the 6.7L Cummins in Ram trucks. The manufacturer says its high strength carbon steel housing and high performance rolled seam exceed OEM pressure requirements, and the cellulose glass media traps contaminants such as rust, dirt, scale and other foreign materials.
The filter earns its price in the fuel system, not just on the shelf. The 6.7 Cummins uses a Bosch high-pressure common-rail injection system that depends on extremely clean fuel, so filtration quality matters more than a bare-minimum swap. The manufacturer says its design is built for high flow rates and capacity, and the PF-4800 carries a 1 Year Limited warranty.
