When it comes to automotive filters, there is no greater known name that K&N Engineering!

K&N Engineering is an American manufacturer that specializes in designing and producing high-performance air filtration systems for automotive, motorcycle, and industrial applications. Founded in 1969 by Ken Johnson and Norm McDonald, K&N initially gained recognition for its oil bath air filters, but it became widely known for its innovative cotton gauze air filters that deliver superior performance compared to traditional paper filters.

K&N is best known for its air filters, which are made from multiple layers of oiled cotton gauze, sandwiched between aluminum mesh. This design allows for higher airflow compared to conventional filters, enhancing engine performance, throttle response, and efficiency. These filters are also reusable and washable, offering long-term cost savings and reducing environmental waste compared to disposable paper filters.

The company offers a variety of products, including air intake kits, cold air intake systems, and performance filters for cars, trucks, motorcycles, and even powersport vehicles. K&N’s cold air intakes, in particular, are popular upgrades for performance enthusiasts, as they provide cooler air to the engine, improving power output and efficiency.

In addition to air filtration products, K&N also manufactures oil filters and performance accessories such as cleaning kits for maintaining their filters. Their products are designed to meet the needs of both casual car enthusiasts and professional racers. The company has a strong presence in the motorsport community and is often seen as a trusted brand for improving engine performance and efficiency.
