K&N's new line of Heavy Duty commercial grade air filters are washable and have been specially engineered for heavy duty trucks, RV's and agricultural equipment. They use a new hybrid filtration medium that's incredibly easy to clean. They can be washed using power sprayers, pressure washers or standard truck washing equipment and they do not require the use of oil. Instead of repeatedly throwing away expensive disposable air filters, now you have a choice. A washable air filter designed to improve engine performance will now make filter maintenance a snap.

  Ordered these filters for my 97 classic 12L detroit. Amazed at the difference in performance of these filters. Will never go back to standard filters again.

  I've installed 2 of these filters on my Freightliner Classic XL...very impressed with the performance. I could tell right away it ran better. It seems that I might have gained a 1/4 mile per gallon better too!
