The aFe Silver Bullet throttle body spacer for BMW V8 N62 engines fits 545i/550i/645Ci/650i/750i (E60/63/64) 2004–2010 and X5 (E53) 2006–2008 4.4/4.8L applications. Its serrated helix entry generates controlled airflow turbulence just before the intake to improve torque, throttle response and efficiency. Machined from T‑6061 billet aluminum, the design reduces the whistle found in other spacers and fits aFe intakes.
