About the brand

K&N Filter

K&N was founded in 1969 in Riverside, California, by Ken Johnson and Norm McDonald, the K and the N of the name. Its filters use washable, reusable oiled cotton gauze, cleaned and re-oiled with a service kit rather than thrown away, and the range here is built on them.

It covers replacement panel filters, complete Performance Air Intake Systems, universal clamp-on, round and conical filters, cabin air filters, crankcase breather filters, carburettor filters and fuel filters. The cleaning and oiling kits, foam wraps, top plates and clips that go with them are listed too.

K&N parts are listed by part number and filter type rather than by car. If you are replacing a K&N filter, its part number is the quickest route; for a universal filter, work from the neck diameter and the space available.

Among the intake brands on TrackToolFactory, K&N has the broadest mix of filter types, from engine and cabin air to breathers, carburettors and fuel. If you prefer a filter that is washed without oil, another panel filter range here uses dry synthetic media.
