Description:
The aFe Silver Bullet throttle body spacers creates turbulence in the air flow at the point just prior to the entry into the engine increasing horsepower, torque and improving throttle response and fuel efficiency. Silver Bullet throttle body spacers are constructed out of durable T-6061 billet aluminum and using a unique serrated/helix entry to create turbulence at the manifold while eliminating the annoying whistle found in other helix only throttle spacers.
This throttle body spacer is 50-state legal (CARB E.O Number D-550-11).

Q: What are throttle body spacers? Why buy them?
A: Throttle body spacers mount between your throttle body and intake manifold and serve to increase airflow by boosting intake velocity and creating turbulence which improves combustion. The net result is a rise in power, crisper throttle response and better overall engine efficiency. This is a modification that has virtually no downside. Normally made of aluminum or high-strength plastic and available in a range of thicknesses for precise engine tuning, throttle body spacers are inexpensive, simple to install, can provide increased power and mpg, and have a stealth look that is hard to detect even by a trained eye. When it comes to bang for the buck power adders, throttle body spacers rank high on our list. Do not overlook this simple upgrade.
