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.

Excellent air filter; this is the second I've bought my first truck really improved it's performance so I got this one for my second truck. The service K&N provides is second to none, from the online purchase to the delivery of my filter I got the best possible service.

From the purchase procedure to the delivery of my filter the K&N store was very professional. The filter is performing very well. I gained pulling power and 0.6mpg . Can't beat that!
