    Riffraff Blue Filter

    Already paid for itself, have washed it from all the dust on the farm. I am happy to be able to buy a few less filters every year.

    Excellant Filter

    I was impressed by how much better this flows than my Napa 6637. It was a direct replacement and I now have zero smoke on hard throttle and I can hear the turbo better. I am very happy I can even wash it out a couple times to allow it to last longer. Riffraff Rocks!
