    Really helped my engine breath. I went from a 6637 to the AFE big boost and noticed a big difference! Big upgrade highly recommended!

    Can move a lot of air!

    Can definitely hear more air being drawn into intake during entire spool up. I can hear the whistle more now, can wait to hear it after I get this 1.0 housing and Billet wheel on.

    I upgraded from the 6637 filter. I have to say the big boost filter definitely lives up to what everyone has said. Definitely know it's breathing better. Can hear the turbo better. Fuel mileage went up. Overall great product when it comes time will be getting another one.

    Amazing Filter!

    Was time to replace my 6637 filter and decided to go with the AFE Big Boost filter. Not only is it reusable and washable in the future but man what a tremendous difference it has made on my '97 Powerstroke! You can definitely tell the difference as well hear the difference. Love the way I can hear my turbo grabbing air under hard accelerations! Very great product! Highly recommend!
