Once installed, the motor sounded smoother and response was crisper. It surely looks better than stock, while providing excellent fitment. Its sits noticeably higher than stock, but still clears the cowl area. The FAST features a 102mm air inlet, but allows use of the stock 90mm throttle body (though this will definitely cost you some horsepower). Injectors, fuel rails and factory accessories fit the same as stock without any clearance issues.
