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

I couldn't find any information on the AFE website or anywhere else on how big the opening of this seal is, I thought it might be some kind of trick but I'd check. The stock throttle body on the 5.7 liter Hemi-Challenger is 80mm in diameter and 71mm in diameter. In addition, you create the throttle directly after the throttle body. No wonder people say this thing whistles like it literally has to go through a straw. I have a 90mm throttle body on my car to let in more air. The idea of choking it almost 20mm is insane.
