Throttle Body Spacer
Silver Bullet Throttle Body Spacer Overview:
This Silver Bullet throttle body spacer produces 6 hp and 14 lbs. x ft. torque and is constructed from precision machined 6061-T6 billet aluminum. It is designed using a serrated/helix design that creates turbulence in the air flow at the point just prior to 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. This spacer works with both the factory and aFe Power cold air intake systems.
Serrated/Helix Design:
The Serrated/Helix combination design creates intake turbulence in the combustion chamber. This turbulence breaks up the fuel which creates a more complete combustion cycle increasing horsepower, torque, and improving throttle response. The Serrated/Helix combination design also reduces intake whistle that occurs with other Helix only designs.
6061-T6 Billet Aluminum Construction:
All Silver Bullet Throttle Body Spacers are precision machined from 6061-T6 billet aluminum for lightweight, high strength, and perfect fit and finish.
Fitment Note:
This throttle body spacer will fit with the factory air intake system.
This throttle body spacer will fit with aFe POWER air intake systems: 51-76214, 54-76214, 54-13035D, and 54-13035R.
Emissions Disclaimer:
Some or all of the applications listed are 50-state exempt, please see D-550-41 for details.
