A Washable Heavy Duty Air Filter K&N has developed a new line of washable commercial grade air filters designed specifically for large turbo diesel engines, class 6-8 over-the-road trucks, agricultural and earth moving equipment, and diesel motorhomes. Built with the unique characteristics of turbo diesel engines in mind, these air filters do not require the use of oil and can be easily cleaned with power sprayers or commercial parts washers. The filters are also designed to provide lower restriction and higher air flow, while delivering exceptional filtration efficiency, and extended service lives. Washable and Reusable K&N HD air filters can be easily cleaned and reused to reduce the cost of replacing air filters. These "depth-loading" air filters feature our washable "lofted" hybrid air filtration medium. They do not require any oil and are robust enough to be cleaned with pressure washers and standard truck washing equipment. Most other heavy duty air filters are built into the canister as a complete non-serviceable unit; the filter and canister must be replaced dirty at the end of a single service interval. A K&N reusable HD filter will reduce the cost of buying disposable filters and canisters over and over. Perhaps even better, when restriction builds beyond a desired level, just wash the filter. So instead of short cycling expensive disposable air filters, keep restriction down and horsepower up with K&N. Designed to Lower Restriction and Improve Horsepower These commercial grade air filters are built from a new hybrid filter medium that incorporates some of the best characteristics of both cotton and synthetic non-woven technologies. They do not require any oil treatment and use a 3-D lofted filter surface to help reduce air filter restriction. Less restriction means more power and better engine efficiency. As air filter restriction goes up, an engine needs to expend energy "pulling" air through the filter. This is wasted energy that is no longer available for power at the wheels. Another air flow benefit with K&N HD air filters is that each time the air filter is washed, restriction is reduced whereas disposable air filters slowly increase in restriction throughout their service life.  Commercial Grade Heavy Duty Construction Our heavy duty air filters are built tough with extra strength and reinforcement to ensure they will keep going for up to 300,000 miles. The Hybrid filter medium is comprised of a thick "lofted" non-woven synthetic media that is co-pleated between 2 layers of powder-coated aluminum screen wire. This reinforced medium is then held between either molded urethane (top or bottom) or between steel top and bottom plates and surrounded by a powder-coated steel cage to help withstand the extreme temperatures and pressures that can be present in large turbo diesel applications. Tried and Tested Each commercial grade diesel air filter design is tested with Fine Grade Test Dust using the ISO 5011 air filtration test protocol to determine filtering efficiency and dust holding capacity. K&N commercial grade air filters are designed to protect vital engine components even after the filter has been cleaned multiple times.
