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.

Installed on a 2011 Tundra and now you would think i have a turbo installed. The truck whistles at about 1 3/4 rpm and continues until about 3 1/2 rpm. I have a flowmaster 50 series dual stainless exhaust and a AFE Pro Dry Sealed CAI. The truck pulls hard and sounds. Smooth. Running 275/70/18 BFG TA KO tire I'm getting 16.2mpg highway and 13.5 to 14 daily driving. If you don't mind the whistle of a turbo you will like this upgrade

Installed on a 2006 BMW X5 (e53) 4.8iS, very straightforward instructions, minimal tools need (10mm socket), half hour install time. Definitely smoothed out idol, and acceleration, mpg improvement!
