aFe Power Silver Bullet Throttle Body Spacer 328i N20 Turbo 12-13

aFe Power Silver Bullet Throttle Body Spacer 328i N20 Turbo 12-13

This Silver Bullet throttle body spacer produces up to 6 hp and 10 lbs. x ft. torque and is constructed from precision machined T-6061 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. Note: This throttle body spacer is 50-state legal for the 2012 328i N20 (CARB E.O Number D-550-5).
