This Silver Bullet throttle body spacer produces up to 6 hp and 10 lbs. x ft. torque and is constructed from precision machined 6061-T6 billet aluminum. Using a serrated/helix design, this spacer 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. This spacer works with the OE and aFe Power cold air intake systems.
This throttle body spacer is 50-state legal (CARB E.O Number D-550-11).Notes: aFe Silver Bullet Throttle Body Spacer
