Review on aFe Power Silver Bullet 46-32007 Dodge Throttle Body Spacer: Enhanced Performance for Your Dodge Vehicle by Matt Norwood

Excellent build quality and easy installation. However, it did absolutely nothing with my 2016 Challenger shaker. I didn't feel any increase in throttle response or power. This produces a high pitched beep which I find annoying. Appears only briefly at certain speeds. Sounds like a belt squeaking. That might work fine on stock cars, but I have a ported throttle body, header, and a custom-tuned cat-back exhaust system. In fact, it seemed to me that I had lost throttle response. I thought it might be worth a try. It's quite expensive for what it's supposed to do. For me this is a comeback. Save money and buy something else.
