The aFe Silver Bullet throttle body spacer bolts between the throttle body and intake manifold on the E36 BMW M3 and M5 inline-six. Its serrated/helix design creates turbulence in the airflow just before the engine, helping the air/fuel charge burn more completely for max gains of +4 HP and +8 ft-lbs of torque, while removing intake whistle. It is precision machined from 6061-T6 billet aluminum.
