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. K&N Hybrid Dryflow 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 means 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.
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 Heavy Duty Diesel Air Filters are designed to improve performance and when air filter restriction becomes too high, simply wash the filter and it’s ready to go again.
K&N Replacement Heavy Duty Diesel Air filtersare designed to be easily washed and reused. These filters are nearly indestructible and after applying the special K&N degreaser 99-0638, they can be sprayed clean with pressure washers, and power sprayers. The filter does not even have to be completely dry to be re-installed.
K&N’s commercial grade diesel air filters are backed by a three year/300,000-mile limited warranty.
The easiest way to find the proper K&N Replacement Heavy Duty Diesel Air Filter for your application is by air filter cross reference using the filter you already have.
