Review on 🔧 aFe Power Silver Bullet Throttle Body Spacer for GM Vehicles - Model 46-34003 by Jason Melvin

Well made product that really works. It wasn't easy to install on my 2011 GMC Yukon Denali 6.2L and it improved my truck's torque and throttle response in the low end. MPG has also improved somewhat. I added this last after installing the AFE cold air intake and then tweaking the Hypertech. All three work great together, providing just enough power and torque to make my truck feel lighter, more responsive to the throttle and just plain fun.
