Heavy-Duty Truck, RV and Agricultural Equipment Filters
Spend a little more now to save a lot more later! K&N Washable Air Filters spare the waste and expense of replacing disposable air filters. These commercial-grade air filters do not require oiling, and they're sturdy enough to be cleaned with power sprayers and pressure washers. Unlike other heavy-duty air filters that are non-serviceable 1-piece units, the filtration medium of a K&N Heavy-Duty Air Filter can be removed from its canister.

The medium is a hybrid of synthetic material and aluminum screen wire. Designed to last 300,000 miles, these reusable filters reduce air restriction and improve filtration efficiency to deliver more power.
