K&N Diesel Filtercharger
Cold Air Intakes
Implementing purification technology formulated and processed over the past 40 years, K&N Diesel air filters supply the security you desire and the performance you need. Based on a groundwork of 6 tiers of oiled cotton gauze situated between two epoxy treated metal screens, K&N air filters for diesel trucks supply improved performance, security and a life long air filter that never requires replacement. Incorporating diesel performance has never been less difficult.

K&N's quest to safely and persistently optimize the horsepower and fuel efficiency of diesel motors begins with developing The World's Finest Air Filter. As great as a K&N OE replacement air filter is, it is restricted by the size of the factory air box. When the airbox is taken out there is room for a more substantial filter. Now K&N's High-Flow Filter Technology can be utilized by a big conical open element filter, supplying additional surface space and all the air that a diesel engine can inhale. The large air filter also grabs and retains far more dirt and particulate matter, boosting the service life until a cleaning cycle is needed (up to 100, 000 miles hinging on driving circumstances).
