The aFe Silver Bullet throttle body spacer for BMW applications (including X5 E53 2004–2006 V8 M62/N62 and select 5/6 series) creates controlled airflow turbulence at the intake entry to increase horsepower, torque, throttle response and improve fuel efficiency. Machined from T-6061 billet aluminum with a serrated helix entry, it eliminates the whistling common to other helix spacers. Fits with aFe intakes and carries a two-year limited warranty.
