The aFe Silver Bullet throttle body spacer is designed to optimize the airflow into your engine's intake manifold. By creating air turbulence at the point of entry, this spacer improves the air/fuel charge for more efficient combustion. This results in measurable gains in horsepower and torque, along with improved throttle response and fuel efficiency. Precision-machined from high-strength T-6061 billet aluminum, it provides a durable, lightweight performance upgrade for your intake tract.

To address a common issue with aftermarket spacers, aFe engineered a unique serrated/helix entry. This design effectively generates the necessary turbulence to improve engine performance while eliminating the high-pitched whistling sound typically associated with helix-only designs. This spacer is built to exacting tolerances for a reliable fit on the factory intake system.
