Great buy. easy to install. you will feel the power difference immediately.(at least i did). you can also hear the turbo a little bit more too. MPG also increases. worth every penny.

I added the Airaid to my 06 Dodge Mega Cab 4x4 3/4 ton diesel along with an MRBP stainless cat back system...WOW what a difference. I get 22 mpg with this beast on the freeway and 17 mpg around town with my foot in it all day long. This was a simple, high quality upgrade that will pay for itself in short order!!!!
