This Silver Bullet throttle body spacer produces up to 12 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 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 Tract:
Adding a Silver Bullet Throttle Body spacer lengthens the intake track which helps increase intake air speed increasing performance and improved throttle response.

Fitment with aFe POWER air intake systems:
This item will work with aFe POWER air intake systems: 51-12172, 54-12172, 51-12162 and 54-12162 but will require modification of the intake tube.

This item will NOT work with aFe POWER air intake systems: 51-72203, 54-72203, 51-72203-R, 54-72202, 51-72202, 58-10003D, 58-10003R, 54-12162-C, 51-12162-C, 54-12172-C, 51-12172-C.
