The aFe Silver Bullet throttle body spacer kit for 2011–2019 Ford Mustang GT 5.0L uses a serrated helix entry to create controlled airflow turbulence just before the intake manifold, aiming to improve horsepower, torque, throttle response and fuel efficiency. Precision-machined from T-6061 billet aluminum, the spacer eliminates the high-pitched whistle found in other designs and is backed by a two-year limited warranty; it also fits with aFe intakes.
