This thing doesn't do anything but whistle. Spend your money on a cold air intake or intake manifold spacer if you want a bit of extra torque and horsepower. I put on the cold air first so I know for a fact that if where the power came from. Absolutely no change after installing this expensive paperweight.

Didn't notice any chance in power or fuel, doesn't worth the paper.

CAI and Borla exhaust made a significat impact that was noticeable. The only thing I noticed was a whistle sound. 8hp is hard to feel and I didn't feel it.

I have not noticed any performance or mpg gains as of yet. I have had 2 guy's ask me if I had a supercharger or a turbo on my hemi do to the whistle effect from this spacer. It was a very simple and fast installation and as usual fast shipping from AA.
