aFe Power Silver Bullet 46-31004 BMW M3 (E36) Throttle Body Spacer

The Silver Bullet throttle body spacer is constructed from precision machined 6061-T6 billet aluminum and is designed using a serrated/helix design that creates turbulence in the airflow 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. During testing, Silver Bullet throttle body spacer have resulted in 4 Horsepower and 8 lbs. x ft. of torque max gains. Serrated/Helix Design: The Serrated/Helix design creates air turbulence in the intake manifold. This turbulence increases the air pressure in the combustion chamber resulting in increased horsepower, torque and improved throttle response. The Serrated/Helix combination design also reduces intake whistle that occurs with other Helix only designs. 6061-T6 Billet Aluminum Construction: All Silver Bullet Throttle Body Spacers are precision machined from 6061-T6 billet aluminum for lightweight, high strength and perfect fit and finish. Longer Intake Track: Adding a Silver Bullet Throttle Body spacer lengthens the intake track which helps increase intake air speed increasing performance and improved throttle response.
