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 did some testing with the K&N Air Filter (38-2011S) on our motor home and had a big increase
in mileage anywhere from .8 to 1.2 of a mile per gallon and I did not baby it ( 70 – 75 mile per hour ).
I’m sure if I would slowed down to 65 I would even see more gain.
