Silver Bullet Throttle Body Spacer
The Silver Bullet throttle body spacer creates turbulance just before the air flow enteres the engine. This increase horsepower and torque while also providing throttle response and fuel efficiency. These throttle body spacers are constructed out of T-6061 billet aluminum and contain a unique serrated entry which allows for turbulence at the manifold. The serrated entry also eliminates an annoying whistle which can be present on other serrated designs.
This spacer is 50-state legal (CARB E.O Number D-550-11)
