    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. K&N: Simpler filter maintenance, Better engine performance.

    Note: "S" or "R" at the end of a part number indicates direction of air flow through the media: Standard (white on the inside) or Reverse (white on the outside). "Standard" flows air from the outside in; "Reverse" flows air from the inside out. The media is designed to flow one way ("depth loading"). Air flow going the wrong way can cause clogging ("surface loading"). K&N recommends using a filter only in its intended direction.

    Applications: Tractor Trailers, Big Rigs, Heavy-Duty Trucks, Recreational Vehicles, Buses, Toterhomes & Totercoaches, Construction Machinery, and Agricultural & Forestry Equipment. Engineered for large turbo diesel engines and Class 6-8 over-the-road trucks. Available in standard or reverse flow.

    • Designed to heavy duty turbo diesel applications
    • Improves power and fuel economy
    • Reusable wash, oil and go design


    38-2006S - K&N Commercial Grade/Heavy-Duty Air Filters is rated 5.0 out of 5 by 1.
    Rated 5 out of 5 by from well made, K&N quality I have used K&N filters on all my vehicles, and always have been happy with the way they worked. I just installed this filter on my recently purchased 2006 diesel pusher. All I can say at this point is it fits very well, and can only save me money . I can't give a performance report at this time.
