aFe Silver Bullet Throttle Body Spacer Kit AFE46-34008 for GM 5.3L V8

he Silver Bullet throttle body spacer is constructed from precision machined 6061-T6 billet aluminum and is designed using a serrated/helix design that creates turbulence in the air flow at the point just prior entry into the engine optimizing the combustion cycle. This turbulence helps the air/fuel charge burn completely providing increased horsepower, torque and improved throttle response. During testing, Silver Bullet throttle body spacers have resulted up to +10 Horsepower and up to +14 lbs. x ft. of torque max gains.

Improve airflow characteristics and throttle response with the aFe Silver Bullet Throttle Body Spacer Kit, Part Number AFE46-34008. Designed for select GM Chevrolet Silverado 1500 and GMC Sierra 1500 applications with the 5.3L V8 engine, this spacer uses a precision-machined 6061-T6 billet aluminum construction for durability and long-term performance.

The serrated helix design creates controlled turbulence in the incoming air stream immediately before it enters the engine. This helps promote more complete combustion of the air/fuel charge, potentially improving horsepower, torque, and throttle response. During testing, Silver Bullet throttle body spacers have produced maximum gains of up to 10 horsepower and 14 lb.-ft. of torque. The design also helps remove throttle body whistle for a smoother driving experience.
