If the Butt Dyno and the boost gauge is any indication this is one of the best mods that has been done to improve the air flow, what a difference.

Fit and quality of the product is very good. I noticed that the boost and throttle was vastly improved on the low end. Torque was much better throughout the entire range.The traction control would come on in second gear as the throttle is very fast and the boost climes to 25 PSI quickly. When the pedal was floored it is wild horse power unleashed.

I would suggest that the inside of the spacer be honded out or tapered slightly to smooth out the air velosity into the intake.
