What kind of performance gains can I expect with this throttle body spacer?

Manufacturer testing indicates potential gains of up to 10 horsepower and 14 lbs-ft of torque. These gains are achieved by creating air turbulence that helps optimize the air/fuel mixture for more complete combustion.

Does this throttle body spacer come with all the necessary hardware for installation?

Yes, this aFe Silver Bullet throttle body spacer includes the necessary installation hardware. Refer to the manufacturer's instructions for specific installation steps.

Will this throttle body spacer make a whistling noise?

The unique serrated/helix design of the aFe Silver Bullet throttle body spacer is intended to create turbulence while eliminating the annoying whistle sometimes found in other helix-only throttle spacers.

Product Details

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.Silver Bullet throttle body spacers create turbulence in the air flow at the point just prior 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.
