    Product arrived a few days early with everything stated and a RiffRaff sticker that has found its home on my shop tool box. Will buy from vendor again:

    Great!

    Wish I lived next to RiffRaff to eliminate shipping but still the best price on these filters. $15 less than autozone and better filter quality. Riffraff's filter has metal mesh on the inside which protects against filters falling apart and getting sucked into your turbo !

    Excellent Filter

    Great Filter and fit perfectly on the UpGr8 4" Aluminum tube. Heavier Duty than other 6637 filters out there. Another great product by RiffRaff.

    This is a better quality filter at a cheaper price than the 6637 replacement filter I bought at NAPA.

    Every time I place an order from Riffraff I always add 1 or 2 of these just to have a spare around. They work great i have been using them for years! Great Price and fast shipping. Dont get much better! Thanks RiffRaff Diesel

    go to this filter

    The conversion to this filter for my f250 was very simply. I have had it for 250 miles I can see more boost than a clean K and N filter
