A K&N oil filter allows oil to flow freely around the engine, and prevents any potentially harmful materials from entering the system and stopping the engine - and car as a whole - from working.
The heavy duty construction of each K&N oil filter ensures that they are built to last, giving you piece of mind that they will continue to allow the free flowing of oil around the engine throughout its life. It is one of the most easily locatable filters and the kind of item that can be changed at home as part of your routine car maintenance checks, or by a professional during the car's annual service.
