 K&N Premium Oil Filters are valued for their durability and ease of dismantling.
 The oil filter cartridges are provided with a 17mm hexagon and can be easily dismantled with commonly used hand tools. 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 chance of damage from stones and debris. The robust construction withstands even the highest oil pressures on the racetrack without bursting.
 The hole on the nut is used to attach the safety wire, which is mandatory on racetracks. This additional technical device gives the discerning consumer a feeling of peace, even away from the racetrack.
