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.

K&N 38-2003R Air Filter Product Reviews

Thursday, May 12, 2016 - Part 38-2003R
K&N shipped immediately. The filter was correct for our 500hp cummings in our motorhome. Just now landed on our first outing with the filter installed. Made hill climbing easier and I don't know yet, but based on my experience so far, I may be getting slightly better mileage. Too early to tell. Our coach is an 08 so no DEF. After market exhaust. Standard filter was about $100 per year, or more frequent if driving in dusty situations. This one is pricey, but worth it. Dusty situation, just rinse it.
