Performance Silver Bullet Throttle Body Spacer for 2014 - 2020 GM Trucks with V8-6.2L Engine by aFe Power

The serrated/helix design creates air turbulence in the intake manifold. This turbulence increases the air pressure in the combustion chamber, resulting in increased performance and improved throttle response. The serrated/helix combination design also reduces intake whistle that occurs with helix-only designs. This Silver Bullet throttle body spacer is precision machined from 6061-T6 billet aluminum for lightweight, high strength, and perfect fit and finish. It features an anodized finish.
