I have a 2013 Ford Mustang with performance ignition coils,cold air intake,tuned length headers and a performance tune. The throttle body spacer was very easy to install. After install I drove the car around and noticed that the you can hear the engine sucking in air. Before you didn't hear anything. Also I felt a little more throttle response.

I bought this spacer to improve hp and throttle response, i did notice a whistle sound from 2500 to 3000 rpm and also more hp when accelarating. It is not a huge improvement but i did notice a little more than stock.
