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. 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. Complete with an orange anodized finish, this Silver Bullet throttle body spacer is sure to stand out in the engine bay. This Silver Bullet throttle body spacer uses all factory mounting locations providing stability and a hassle-free installation.
