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

I have a 2012 GMC 1500. Mileage 55,000 miles. I changed the exhaust from stock to a true dual using two Flowmaster 40s and a Dump 45. I changed the intake to cold air. The Silver Bullet is a great addition to this system. My wife installed the product in less than 30 minutes. Now I just have to make CHIP (program) and change a few little things with air and fuel.
