Description
The aFe POWER Silver Bullet Throttle Body Spacer is engineered to enhance airflow efficiency, throttle response, and overall engine performance for GM 5.3L V8 trucks and SUVs. Designed using precision machining and proven airflow technology, this spacer improves air velocity and fuel atomization just before the air enters the engine, resulting in measurable performance gains and a more responsive driving experience.
At the core of the Silver Bullet spacer is a unique serrated/helix entry design that creates controlled airflow turbulence within the intake stream. This turbulence promotes more complete fuel atomization in the combustion chamber, improving combustion efficiency while delivering dyno-proven gains of up to +8 horsepower and +12 lb-ft of torque. Unlike traditional helix-only spacers, this design also eliminates the annoying intake whistle, providing smooth and quiet operation.
Constructed from precision-machined 6061-T6 billet aluminum, the Silver Bullet throttle body spacer offers excellent strength, lightweight durability, and a perfect factory-style fit. By slightly lengthening the intake tract, the spacer increases intake air speed, further improving throttle response and low-to-mid-range performance.
Installation is quick and hassle-free, utilizing all factory mounting locations with no cutting or modification required. Designed as a direct bolt-on upgrade, the Silver Bullet throttle body spacer delivers noticeable performance improvements with minimal installation time.
Backed by aFe POWER’s commitment to performance engineering, this spacer is an ideal upgrade for drivers seeking improved throttle response, increased power, and enhanced drivability.
