*The aFe Silver Bullet Throttle Body Spacer works with the OE and aFe cold air intake systems.

aFe's Silver Bullet Throttle Body Spacer is designed using a serrated/helix design that creates turbulence in the airflow at the point just prior to entry into the engine. This direction optimizes the combustion cycle which produces an incredible 16 horsepower and 17 ft-lbs of torque. Turbulence helps the air/fuel charge burn more thoroughly, and also reduces intake whistle that occurs with other helix-only designs.

The aFe Silver Bullet Throttle Body Spacer is precision machined from T-6061 billet aluminum for lightweight, high strength, and a perfect fit and finish on your F-150. A brand-new gasket and all the necessary hardware required for installation are included!
