The aFe Silver Bullet Throttle Body Spacer Kit is designed for select Ford F-150 applications equipped with the 5.4L V8 engine. Part number AFE46-33002 uses a precision-machined T-6061 billet aluminum construction and a specialized serrated helix entry to create controlled turbulence in the incoming air stream. This design helps improve airflow into the intake manifold and may enhance horsepower, torque, throttle response, and fuel efficiency when used with a properly matched intake system.

Unlike helix-only throttle body spacers that can produce an unwanted whistle, the Silver Bullet design incorporates serrated and helix surfaces to promote air movement while reducing irritating intake noise. The spacer increases air volume at the throttle body and is compatible with aFe intake systems, making it a practical upgrade for drivers seeking improved engine response and airflow without replacing the complete intake assembly. Installation is intended for the designated Ford applications, and the included hardware and components support a straightforward installation.
