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.

Description
K&N 57i Series induction kits are specifically designed for each different vehicle and will free your car from the size restriction that comes with the factory air box. These economical kits can take a variety of different forms based on vehicle characteristics and available space under the hood. Each kit is designed to provide power throughout the RPM range. The extra surface area of these open-air air filters provides even more airflow at lower restriction than a K&N O/E replacement filter which is limited to the size of the factory air box. The larger air filter also captures and holds more dirt increasing its service life before a cleaning is required (up to 100,000 miles). The filter is either directly attached to the engine carburetor or throttle body or indirectly through a tube assembly running from the filter to the engine. All adapters are made from high quality materials such as steel, aluminum, silicon or reinforced nylon to ensure long life. 57i Series Intakes are not legal for use in California and other US States adopting California emission standards.
