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.

Product Reviews

  Good product. Arrived on time and fits as it should. Makes my customers happy.
Lavern Dykes Vern's Garage, Swansea, South Carolina
  This filter is great I have seen a great fuel mileage. I would recommend this filter.
Enriqueta San Diego, California
  Awesome! Lasts long enough to pay for itself several times over versus paper filters.
Robert Virginia Beach, Virginia
  Awesome filter. Lasts 10 times longer than standard filters. It's cost vs standard pays for itself several times over.
Robert Williams Virginia
  Excellent product. .5 to 1 mpg increase.

  As an owner operator of my own truck, it's nice to have that extra edge. I pull sea containers in and out of the Jacksonville port and I do a lot of overweight 80,000lbs plus. The filter is in a 1998 Freightliner Century Class with a Cummings 500 HP with a 10 speed transmission and a flow through exhaust. I run only in the southeast there are only some hills and my fuel average is 6.7 to 7.2 running 65mph at 2,500 rmp.

  Very hard time getting correct part number for my vehicle. Old K&N Number not cross referencing with new K&N number??? Great product, would not have gone through hassle of tracking down correct part number myself if filter wasn't worth the effort.
