Can hear supercharger screaming now. Lot better proformance now. Just need to change pulley on supercharger now. Horsepower in there just wants out.

Installation couldn't be easier. 4 bolts out, 4 bolts in. I reused the stock bolts as they were the same length as the ones which came with the spacer. I have gotten a .2 mpg increase with the spacer installed and have noticed a slightly quicker throttle response.
