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 Tract:
Adding a Silver Bullet Throttle Body spacer lengthens the intake tract which helps increasing intake air speed increasing performance and improved throttle response.

Installation Is A Snap:
This Silver Bullet throttle body spacer uses all factory mounting locations providing stability and a hassle-free installation.

Emissions Disclaimer:
Some or all of the applications listed are 50-state exempt, please see D-550-42 for details.

Super easy installation. I bought this with the aFe intake and you can really feel the difference. No crazy whistle either.
