Improve airflow and throttle response with the aFe Silver Bullet Throttle Body Spacer Kit, Part Number 46-31007. Designed for select BMW applications equipped with the 3.0L turbocharged inline-six engine, this spacer creates controlled turbulence at the intake manifold entrance to help optimize air distribution. The result can include improved throttle response, increased horsepower and torque, and enhanced fuel efficiency when used with a properly matched intake system.

Manufactured from durable T-6061 billet aluminum, the aFe Silver Bullet spacer uses a specialized serrated and helix entry design. This configuration promotes air turbulence while avoiding the excessive whistle commonly associated with helix-only throttle body spacers. The precision-machined construction supports long-term durability, and the design is compatible with aFe intake systems for a straightforward performance upgrade. The kit is backed by a 2-year limited warranty.
