aFe Silver Bullet throttle body spacer engineered for BMW 325i (E46) 2001–2006 with the M54 2.5L inline-six. Machined from T-6061 billet aluminum, the Silver Bullet uses a serrated helix entry to create turbulence that enhances throttle response, torque and airflow while avoiding the whistle associated with simpler helix designs. The spacer installs at the throttle body and fits with aFe intake systems.
