The aFe Silver Bullet throttle body spacer installs between the throttle body and intake manifold, using a serrated/helix entry to generate 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 Honda Accord/Odyssey/Pilot/Ridgeline and Acura TL/TSX/MDX/RL models with the 3.5L V6.
