Like all K&N HD filters, filter number 38-2012S is comprised of commercial grade materials in order to ensure the demands of professional drivers and their rigs are easily met. HD filter 38-2012S uses a hybrid filter medium which is comprised of a thick non-woven pleated synthetic media that is placed between 2 layers of powder-coated aluminum screen wire. This reinforced medium is held between a steel top and bottom plate.  This design helps the reusable filter withstand the extreme conditions present in large turbo diesel applications.

HD filter 38-2012S is a short standard flow radial seal air filter and has a rubber flange that will fit over the inlet tube. Air flow on this hybrid filter media is directional.  Air is designed to flow through the red side of the media and come out the white inner side of the filter media before going into the engine.

HD filter 38-2012S can be easily cleaned using K&N's HD cleaner part number 99-0638 and a hose. These filters are so durable that drivers can even use power washers or truck washing equipment with the HD cleaner to clean the filter then use pressurized air to blow the excess water off and immediately reinstall. This means no down time for drivers. These filters are backed by K&N's 3 year 300,000 mile commercial grade air filter warranty. These air filters can replace up to ten disposable air filters.

Due to the numerous combinations of chassis with engines, the best way to determine if this filter is appropriate for your rig is to look for a cross reference with your existing filter.
