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. These spacers are finished off in a bright orange anodizing providing a custom look. Adding Silver Bullet Throttle Body spacers lengthens the intake tract which helps increase intake air speed, increasing performance, and improved throttle response. These Silver Bullet throttle body spacers use all factory mounting locations providing stability and a hassle-free installation.
