K&N air filters are designed to achieve high, virtually unrestricted air flow while maintaining filtration levels critical to ensure long engine life. All filters are constructed with ultra-strong molded pliable rubber flanges which absorb vibration and allow for secure attachment and can also be stretched up to 1/16 (1.5mm) to fit in-between sizes. K&N Universal air filters are available in round, tapered (cone style) and oval designs, for just about any special application. K&N was founded in California in the early 1960’s by Ken Johnson and Norm McDonald. Their racing experience identified a need for better performing air filters and in 1969, K&N invented the reusable high flow cotton air filter. K&N air filters demonstrated great performance and durability, and manufacturing these air filters soon became the primary focus of the company. They continued to develop and improve these products and now produce air filters and related products for cars, trucks, SUV’s, motorcycles, ATV’s, and other applications. K&N has maintained very active involvement in racing and motorsports throughout its history and has supplied championship-winning teams in most forms of motorsport. This racing heritage and involvement helps to develop better products for all types of vehicles and engines. Washable & reusable, most are pre-oiled and ready to ride! No fuel management modifications are normally required to obtain increased performance. Fits directly into OEM airbox with application specific sealing bead ensuring a precise fit. Multi-layers of woven cotton gauze media offers excellent filtration. Pleated cotton media provides a large filtration area offering low restriction and long service intervals. If one of these products ever fails to provide complete satisfaction, K&N will replace it. At MPW we strive to provide the best quality goods and excellent service to our customers.
