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 38-2001R Air Filter Product Reviews

Tuesday, June 21, 2016 - Part 38-2001R
Was the right part. Web order easy to do. Took five days to get delivered, but we were out on the date scheduled on the tracking link.

Filter came fast as promised. Installed it in a 2007 Tiffin motor home with 400 Cummins deisel pusher. Little too early to tell exactly the mileage improvement but it is definitely better. Pulls hills better and am guessing at this point maybe up to .5 mpg improvement.
