The aFe Silver Bullet throttle body spacer installs between the throttle body and intake manifold on the 3.5L and 3.7L inline-5 Colorado, Canyon, Hummer H3 and Isuzu i-series, lengthening the intake track and using a serrated/helix entry to create turbulence that sharpens throttle response and performance. It is precision-machined from 6061-T6 billet aluminum with a black anodized finish, and the serrated design reduces the whistle found in helix-only spacers (US Pat. 07055513). It uses all factory mounting locations and includes a gasket for a proper seal.
