Review on 🚀 GM 5.3L Throttle Body Spacer by Volant Performance - Model 725253 by Kevin Nelson

I installed this with Dynamics Cold Air Intake on a 2008 GMC Sierra 1500 that already had a Flow Master exhaust system and was noticing a significant amount of bass, torque and more breath noise by then I have the mileage noticed because i just got it but definitely great together. I can't figure out what does what separately, but I've been told to do it together to make it worthwhile. My reason for not all 5 stars is that the 4 mounting screws that came with the kit were 1/2" too short and misthreaded so I went out and bought the correct ones for less than $3 otherwise I am satisfied.
