This line of K&N air filters takes the design and performance of a traditional K&N air filter and transforms it into a large durable filter capable of withstanding the abuse of commercial vehicles.  These air filters use a special non-oiled synthetic filter media.

The K&N 38-2022S is one of these heavy duty filters, designed with layered synthetic media and a tough metal protective shell. The filter media is a lofted non-woven synthetic media, held together with K&N's famous epoxy coated aluminum mesh. The metal shell encasing the filter media is made with black powder coated steel.

This 12 pound filter is almost 2 feet long.  It is a washable, reusable air filter that comes with a 3 year/300,000 mile limited warranty. Instead of buying expensive, throw away air filters, you can save money by buying this re-usable heavy duty K&N filter. The 38-2022S is a standard flow filter, so the air comes in from the outside of the filter to the center before entering the engine. The 38-2022S can be cleaned from the inside out with a pressure washer, power sprayer, or standard truck cleaning equipment along with K&N's Heavy Duty Air Filter Cleaner. Once the filter is cleaned and dried it can be reinstalled and used again.

The K&N 38-2022S is designed to increase air flow over the stock air filter and boost performance. They are engineered to provide superior engine protection. The K&N 38-2022S has a radial seal on the bottom of the filter. As the filter sits inside of its housing this rubber circle seals the filter to prevent bypassing of filtration by pressing against the inner lip of the filter's flange.
