aFe POWER Silver Bullet Throttle Body Spacer

This Silver Bullet throttle body spacer produces 6 hp and 12 lbs. x ft. torque* and 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. 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 Helix only designs.

6061-T6 Billet Aluminum Construction: All Silver Bullet Throttle Body Spacers are constructed from 6061-T6 billet aluminum precision machined 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 increasing 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).
