    Like a new set of lungs

    I have a '96 OBS I bought new and still work to death today. At 260k miles I thought what the heck... Should of done this years ago, she can breathe and I am excited about tackling some other issues that are holding her back.

    Excellent Product

    By far the best and most cost effective intake solution for our 7.3 Powerstrokes. Sounds great, spools up fast, noticeable turbo whistle.

    Worth the money...

    Running this on my '96 7.3L...definitely noticed a "butt dyno" improvement in how the truck runs; can just tell it's breathing better. Install was a piece of cake and had it in probably in 15 minutes. Definitely worth the price.
