This Silver Bullet throttle body spacer produces up to 6 hp and 10 lbs. x ft. torque and is constructed from precision machined 6061-T6 billet aluminum. Using a serrated/helix design, this spacer 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. This spacer works with the OE 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 light weight, high strength and perfect fit and finish.
Longer Intake Track: Adding a Silver Bullet Throttle Body spacer lengthens the intake track which helps increase intake air speed increasing performance and improved throttle response.
This throttle body spacer is 50-state legal (CARB E.O Number D-550-11/D-550-17).
