Robust construction for extreme conditions

K& N oil filters are characterized by many product features that exceed the requirements of vehicle manufacturers.

Thicker case walls are used for added strength and durability to reduce the risk of damage from rocks and debris.

The robust construction withstands the highest oil pressures even on the race track without bursting.

The hole on the nut is used to attach the safety wire, which is mandatory on race tracks.

This additional technical device gives the discerning consumer a reassuring feeling even off the racetrack.
