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.

 I have had K&N filters on everything from air compressors, to snowmobiles. from f150's to f350 powerstroke. Now on my 2013 volvo d13 truck engine I gained 2-3 lbs of boost. Very substantial, more air equals better more efficient burn and equals more power with less money. Thank you K&N for who you are and what you do. Tom

 The savings of having this filter alone makes it worth it. Not certain on any performance gains. Wish K&N would work on some of the other HD intake filters that aren't cylindrical.
