Air Filters For Your Trucks

So what air filters do you run in your gas/Diesels besides K&N? Time to replace mine and looking toward Fleetgaurd but could o with the OE Mopar.

  • I have been using Fleetguard's for over 20 years and over 1/2 million miles with no issue. Fuel, oil and air filters in my Cummins powered truck.
    I personally would never run a K&N on a diesel truck. The stock filter is more than capable of providing enough air.
  • I pitched the K&N that was on mine when I bought it. IMO a diesel flows so much air the K&N needs to be thoroughly, and I do mean thoroughly, cleaned often. The one I pitched had crud deep down in the pleats. I replaced it with a Donaladson BHAF. This is on a 2001 Cummins.
