Description
The aFe POWER Silver Bullet Throttle Body Spacer is engineered to improve airflow efficiency, throttle response, and overall drivability for 2007–2013 GM full-size trucks and SUVs equipped with V8 engines. By creating controlled airflow turbulence just before the intake manifold, this spacer enhances combustion efficiency and delivers noticeable performance improvements without permanent vehicle modifications.
At the core of the Silver Bullet spacer is a patented serrated/helix entry design (US Patent 7,055,513) that promotes increased air turbulence within the intake manifold. This turbulence improves air pressure and fuel atomization in the combustion chamber, resulting in quicker throttle response and stronger low- to mid-range performance. Unlike helix-only designs, the serrated/helix configuration also reduces intake whistle, ensuring smooth and quiet operation.
The spacer is precision-machined from durable 6061-T6 billet aluminum, offering an optimal balance of lightweight construction, high strength, and corrosion resistance. Its exacting fit and finish ensure proper sealing and long-term durability under demanding driving conditions.
Installation is quick and hassle-free, utilizing all factory mounting locations for a secure, factory-style fit. A supplied gasket ensures a perfect seal, and no cutting or drilling is required. This throttle body spacer is also fully compatible with aFe POWER Momentum GT Cold Air Intake Systems (P/N: 51-74105 and 54-74105), making it an ideal complement to a full intake upgrade.
Backed by aFe POWER’s commitment to performance engineering, the Silver Bullet throttle body spacer is a simple yet effective upgrade for drivers seeking improved throttle response and enhanced engine efficiency.
