K&N's 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 air filter maintenance a snap.

K&N 38-2001S Air Filter Product Reviews

Wednesday, June 8, 2016 - Part 38-2001S
I was a little leery about it, but it was the best thing I did for my motorhome. I have a 330 Cummins in my bus and I can go up the mountain passes about 10 miles an hour faster than before. Seems to be getting better fuel mileage too, but haven't checked it yet. I'm impressed, didn't think there would be that much of a difference.
