 K&N Premium Oil Filters are valued for their durability and easy disassembly.
 The oil filter cartridges are provided with a 17mm hexagon and can easily be 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 in the nut is used to attach the safety wire that is required on racetracks. This additional technical device gives the discerning consumer a feeling of peace away from the racetrack.
