The aFe Silver Bullet throttle body spacer mounts between the throttle body and intake manifold, where its patented serrated/helix design (US PAT 07055513) creates air turbulence in the intake manifold to raise combustion-chamber air pressure for added horsepower, torque and improved throttle response. Precision-machined from 6061-T6 billet aluminum, the serrated/helix combination also reduces the intake whistle produced by helix-only designs. It includes gaskets and uses all factory mounting locations.
