The aFe Silver Bullet throttle body spacer fits the 4.2L inline-six in the Chevrolet Trailblazer, GMC Envoy, and related GM SUVs. Its serrated/helix bore creates turbulence in the intake charge to raise combustion-chamber air pressure for stronger throttle response, while the combined pattern reduces the whistle of helix-only designs. Machined from billet aluminum with a black anodized finish, it uses the factory mounting locations and includes a gasket for a leak-free seal.
