aFe Silver Bullet Throttle Body Spacers for 95-99 BMW M3 (E36) 3.0L, 3.2L - 46-31004

aFe Silver Bullet Throttle Body Spacers are precision-machined from T-6061 billet aluminum to enhance engine performance by creating turbulence in the airflow just before it enters the engine. This turbulence ensures a more thorough mix of the air-fuel charge, resulting in a complete burn that increases horsepower, torque, and improves throttle response and fuel efficiency. The unique serrated/helix design not only optimizes the combustion cycle but also eliminates the whistling sound commonly associated with traditional helix-only spacers. By increasing the volume between the throttle and cylinder, the spacers improve volumetric efficiency. Testing has shown gains of up to 4 horsepower and 8 lbs.-ft. of torque. Constructed from durable 6061-T6 billet aluminum, these spacers are designed to deliver reliable performance and are a practical upgrade for those seeking enhanced engine efficiency and power.
