Review on 🚀 Rough Country Throttle Body Spacer - 1999-2006 Chevy/GMC 1500-1196 by Brandon Henry

First of all I don't understand why people keep saying they make a whistling noise. I believe it's the installer as I have no problem. There was absolutely no problem with the installation, I didn't even use the instructions as it's pretty easy to understand the process by looking at the details. (I have a power throttle body) I don't know about mileage increase as I really don't care that the sled is heavy and my driving habits are not conducive to fuel economy. What I was looking for was increased throttle response and less power acceleration. Not a huge win, but an improvement that's okay considering the cost. If you really think a piece at this price will fetch a huge profit then maybe go ahead as you will be disappointed. This is part of the optimization, nothing more, nothing less.
