aFe Power 2014 5.3L GM Throttle Body Spacer 
This 6061-T6 billet aluminum Silver Bullet throttle-body spacer from aFe Power is said to add 8hp to 2014 5.3L GM V8s and up to 12 lbs./ft. of torque.
The serrated/helix design lengthens the intake track and creates turbulence in the air flow just prior to entering the engine.
This helps the air/fuel charge burn completely providing increased horsepower, torque and improved throttle response.
The 50-state legal Silver Bullet ($118) also reduces intake whistle that occurs with other Helix-only designs.
