K&N Engineering is an American company that offers automotive air filters and air intake systems. It also manufactures oil filters and air intake system accessories. The chief qualities of the brand's air filters are that they are washable and highly-durable. Established in 1964 by Ken Johnson and Norm McDonald, its headquarters are in Riverside, California. The brand markets more than 5000 products in various markets including watercrafts, boats and agriculture, in over 30 countries across the world. K&N has established operations in the Netherlands and United Kingdom. K&N's parts are available for various makes including Bentley, Ford, Fiat, Acura, Rolls Royce and Mitsubishi.


Initially, the company manufactured motorcycles and motorcycle parts, and also assisted the K&N factory race team. As it manufactured parts for the racing team, the company realized the importance of improving its air filters. After extensive research for improving air filters, K&N patented the reusable high-flow cotton air filter in 1969. The brand started focusing on the development of air filters from that point, which led to various innovations in the following years. Towards the end of the 1980s, bolt-on performance air intake kits were invented by the company to replace factory air boxes and filters. The company entered into the production of air intake systems in 1992.


The line of products manufactured under the air filter range includes air filter wraps, universal clamp-on air filters, crankcase vent air filters, plenums and weber carburetor adapters, and accessories. The air filter wraps are offered in different types including PreCharger® and DryCharger®. The PreCharger® air filter wraps are designed for use in dusty conditions and they fit various applications. The DryCharger® is built to keep water or dirt away from the filter. The brand's universal clamp-on air filters provide the highest-level of filtration and also act as a dampener for vibrations. They are available in various styles including round straight, round tapered, oval straight and dual flange straight oval. K&N builds a line of plenums designed for cold air intakes in mini and custom variations. To add to the range of air filter parts, stubstacks are also manufactured by the company. The stubstacks improve the airflow of carburetors by reducing the restriction of air flow around the choke horn.

K&N's oil filters provide excellent filtration efficiency when used with both synthetic and traditional oils. Premium Wrench-Off, Pro-Series, Cartridge and Billet are some of the oil filters manufactured by the brand. The company's air intake systems provide a considerable gain in horsepower and fit a wide range of applications. 57 Series Gen II Air Intake Kits, 77 Series high performance air intake systems, and 69 Series Typhoon® air intake systems are some series of air intake systems manufactured by K&N. The brand's air filters and air intake systems carry a million-mile limited warranty. stocks authentic K&N air filters and other parts at the best prices. Efficient air filters can actually prolong the life of other engine components, as they filter out most of the dirt that can be detrimental to the engine. This is the key idea for K&N in developing highly-efficient air filters and intake systems.
