The aFe Silver Bullet throttle body spacer for Ford F‑150 models (1997–2010 4.6L and 1997–2003 5.4L) introduces a serrated/helix entrance to create intake turbulence that improves throttle response, horsepower and torque while reducing intake whistle. Precision-machined from T‑6061 billet aluminum, the spacer increases air volume and is intended to work with compatible aFe intake systems, backed by a two-year limited warranty.
