Founded in 1969, K&N is headquartered in Riverside, California, in a complex of 10 buildings comprising nearly 400,000 square feet.[2] K&N also operates facilities in England, the Netherlands, and China.[1][3] K&N is owned by Goldman Sachs.[4]

History[]

K&N air filter (center) and recharge kit

K&N was founded by Ken Johnson and Norm McDonald in 1963.[1] The name K&N came from the first letters in the founders' first names. Johnson and McDonald sold motorcycles and motorcycle parts and supported a K&N factory race team. Air filters soon became the primary focus of the company. In the late 1980s, K&N introduced a bolt-on air intake kit to replace the factory air box and air filter. K&N also released a line of oil filters with a stamped hex to accept a standard wrench for installation and removal. K&N has maintained very active involvement in racing and motorsports throughout its history, including the NASCAR Pro Series East and West,[5] and the King of the West 410 Sprint Car Series.[6]

Racing[]

In February 2002, K&N entered the 24 Hours of Daytona race where up-and-coming driver, Joey Scarallo, was invited to be a driver.[citation needed]

K&N's claims for their air filters have been the subject of some controversy, with 3rd-party tests finding that K&N's oiled cotton gauze filters are less efficient and let more dirt into the engine than original-equipment paper filters, and that they become increasingly restrictive as they are coated with particulates.[7] (air filters in general become more airflow-restrictive as they collect contaminants, but efficiency typically increases for the majority of a filter’s service life.[8])

There are also issues caused by oiled air filters on modern engines that use MAF sensors, which can stop working correctly when they get fouled by oil from an oiled-gauze air filter.[9]
