Product Description

The aFe 46-31007 Silver Bullet Throttle Body Spacer is engineered to enhance the performance of BMW vehicles equipped with the N55 3.0L turbocharged engine. By sitting between the throttle body and intake manifold, this spacer increases airflow velocity and improves the air/fuel mixture, resulting in enhanced throttle response and engine efficiency.

Constructed from durable 6061-T6 billet aluminum and featuring a unique serrated/helix entry design, the spacer creates turbulence that aids in better fuel atomization, leading to dyno-proven gains of up to +6 horsepower and +13 lb-ft of torque. The design also reduces the intake manifold whistle noise commonly associated with other spacers.

Installation is straightforward with the included custom-made screws, ensuring a secure and non-damaging connection to your plastic intake manifold. The spacer is CARB-compliant with EO# D-550-11/D-550-17, making it legal for use in all 50 states.
