The aFe Silver Bullet throttle body spacer installs between the throttle body and intake manifold, using a serrated/helix entry to create turbulence in the incoming air for sharper throttle response and added low-end torque and horsepower. It is precision-machined from T-6061 billet aluminum, and the serrated design cancels the whistle found on helix-only spacers. The spacer uses factory mounting points and fits the Toyota Tacoma, 4Runner, FJ Cruiser and Tundra with the 4.0L V6.
