aFe 18-21 Ford Mustang GT 5.0L 85mm Billet Throttle BodyNot only does our design out flow the OE by 17% at WOT (measured at 4 H2O restriction), the air flow in the 80% range of throttle blade opening is also dramatically improved, offering much smoother power delivery during spirited driving in the upper RPM range. This is achieved through careful engineering, billet construction and precision machining, allowing for smoother transitions, a thin leading edge and an aerodynamically improved design. The
