This kit was easy to install!!! Just had to trim the old air box a little so the hood would close good. Just need more business cards to hand out from riffraff

Very impressed with the quality well worth the money.

Very happy with my purchase. Quick delivery, everything included and fit nicely. I replaced my stock box and filter with the 6637 kit. The quality is high and I have some decent games. One prior review mentions the noise, the noise difference is very slight, but how could you not love that intake sound... I usually only hear a difference after I get on it and let off, sounds awesome!! Quicker throttle response, and you can really tell the truck is breathing much easier and the restriction is gone. Next purchase through Riffraff will be a new turbo wheel. Thank you Riffraff for the great kit, at a fair price.

When I bought this product I was still running the stock intake. As I expected I seen pretty decent gains ,which I was after. The only downside is the noise. But hey well worth it.

no problems fit perfect although i purchased the big blue filter not the 6637

This has made a huge difference thanks

My airbox was cracked and broken so I ordered this kit instead of repairing or replacing the stock airbox. Install is easy and includes everything needed.

I figured for the money it was worth giving this a try. I was pleased wit the quality of the kit and the fact it included everything needed to complete the install. Using with the filter cover as well. Haven't done any road trips yet to see if I pick up any MPG's.

Everything you need is included and instructions are included. Piece of cake to install.
