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 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 factory and aFe Power cold air intake systems.
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.

- Best on the market...
- Very easy install. It does give the slight whistle at full throttle. It is a great add to the aFepower cold air intake perfect combination...
