K&N Heavy-Duty Replacement Air Filters

K&N heavy-duty replacement air filters are designed to provide exceptional filtration for your large turbo diesel engine, Class 6-8 over-the-road truck, agricultural and earth-moving equipment, and diesel RVs. These filters feature extra-tough, commercial-grade construction that withstands the extreme temperatures and pressures that can be present in large turbo diesel applications. The replacement filters are made with K&N's washable lofted hybrid air filtration media, reducing air restriction for more power and better engine efficiency with each cleaning. They do not require oiling and are easily cleaned with pressure washers and standard truck-washing equipment. K&N heavy-duty replacement air filters will keep going for up to 300,000 miles of high performance filtering! Order the universal model or the size and style designed for your vehicle application.
