K&N heavy duty air filters have a directional flow hybrid air filtration medium made from non-woven synthetic material that operates with low restriction and offers excellent protection under some of the most extreme driving conditions. Less restriction means more power and better engine efficiency. This is a good thing when climbing steep grades or even crossing the Great Plains in a vehicle that weighs more than 15,000 pounds.
Unlike K&N's automotive replacement air filters, K&N heavy duty air filters like 38-2011S and 38-2025S do not require oil, so they can be washed almost anywhere. Cleaning is a simple matter of spraying on Heavy Duty air filter cleaner, allowing it to set for a short time, rinsing the filter then allowing it to dry. An air compressor can be used on a lower setting to speed up the drying process. Once the filter has been dried simply re-install it and you will be back on the road in less time than it takes to wash down the rest of the truck.
Parts 38-2011S and 38-2025S have a radial seal, matching the OEM replacements they cross reference to below, as well as, a metal support grate on the outer edge, for extra strength. Heavy duty air filters 38-2011S and 38-2025S fit in place of the factory OEM elements and include basic installation instructions. K&N relies on the utmost quality when designing and manufacturing their heavy duty diesel products and K&N stands behind them with a 300,000 Mile Limited Warranty.
