Heavy-Duty Construction


The K&N oil filter boasts of thick canister walls for durability and extra sturdiness. Also, this reduces the risk of damage from debris and rocks. The filters can withstand high oil pressures, especially in a racing environment. 

The safety wire attachment prevents blown filters from getting on the track and causing a hazard to other race vehicles.

High Flow Rate


K&N oil filters have resin cellulose filter media that enables high flow rates while offering excellent filtrations. The flow rate comes in handy for racing cars that use heavier grade oil and require quicker pumping than on standard vehicles.

 

You don’t have to worry about the loss of pressure through the filtering process because the engine circulates at high GPM rates. The filter works with synthetic engine oils, which help to provide flow performance even in cold conditions.

Warranty


The K&N oil filter is covered by a limited warranty from defects in quality and materials. That means if the oil filter malfunctioned when it was being installed, you could get an exchange.
