    6637 Filter Kit

    Posted by Steve B on Jan 28th 2014

    Installed on a 2000 F250SD, quick & easy. First thing noticed is less nickels (black smoke) out the tail pipe. I'm looking forward to less snow on the ground to see what it will do in daily driving & pulling a 10k 5th wheel.

    Great product at a great price. Everything came how it was supposed to, and fit perfectly on my 2002 F-350. Made a huge difference compared to my factory filter setup, the truck breathes much better now. Definitely recommend this product.

    A great option for those who use their truck in dusty conditions or just don't want to spend $250 on a big name intake. No complaints on this product, highly recommend it!

    Best Price!

    Can't beat this deal here. Installed it on my 2001 f250 and there is a noticeable difference from stock.

    Simple install, I found that you can retain all the stock parts (sans the top pieces) by removing the securing bolts from underneath the battery/intake box and sliding the whole thing forward roughly. 2-3 inches. It allowed for the extra clearance and now drilling/ cutting!

    Definitely worth the buy considering the price!

    Simple, effective and cheap!

    After much consideration I ended up with this intake system. First off its easy to install and looks clean under the hood. There are many guys around running the Napa intake and this hardware is the exact same.
