The Silver Bullet throttle body spacer is constructed from precision machined T-6061 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. In recent testing this spacer produces up to 10 HP and 8 lbs. x ft. of torque This spacer works with the OE. A slight modification is needed to the intake tube when used with the Takeda intake system Part number TM-1018P-X.
This throttle body spacer is 50-state legal (CARB E.O Number D-550-11).
