    Best filter. Oiled aftermarket filters are crap compared to this

    Used my aftermarket intake tube and had to remove box just to make this big thing fit. But with this filter and bag I am very pleased!

    Dusty environment,

    I live in Outback Australia and the 6637 look after the big old Power Stroke just fine. Every 500 give them a light blow out from the inside and then the light globe test and I use the Riffraff covers and the combination has been a winner. Thanks Team.

    MASSIVE filter

    Posted by John on Jun 21st 2016

    This thing is huge. Barely fits between my battery and my fuse panel on my '96 F250 PSD. I opted not to go for the kit, as I had a spare piece of 4 inch exhaust pipe laying around. I used a straight piece and was able to twist the rubber connector to make it fit well. Great product, need to pick up a filter bag now!

    Fits perfect with kit. Increases airflow.

    It also is more economical than stock. It lasts longer than stock. Increased responsiveness. 1995 F250 OBS
