A K&N Replacement Heavy Duty Diesel Air Filter is constructed with extra strength and reinforcements to withstand the harsh conditions that can be found in commercial use. Forming the basis of a K&N washable HD Diesel air filter is K&N’s Hybrid Dryflow^® Air Filter media. The robust Dryflow Air Filter media is comprised of lofted non-woven synthetic fibers to create a three-dimensional medium capable of providing high airflow, dirt capacity, and filtration efficiency without sacrificing engine protection.

K&N’s rugged synthetic air filter media is pleated and placed between two powder-coated aluminum screens which is then held between a top plate or molded urethane end cap and molded urethane seal. These ends are molded into a powder-coated steel cage to help withstand extreme temperatures and pressure. This ensures that a K&N commercial grade diesel air filter will not collapse or lose its seal under the high levels of compression that may be encountered in large turbo diesel applications.
