Street legal for late model 5L Ford Mustangs. 65 Millimeters size is ideal for stock manifolds. 70 Millimeters is the optimum choice for the performer 5.0/performer RPM 5.0 EFI intake and total power package (70 Millimeters gained 10 Horsepower over stock throttle body). 75 Millimeters is intended for more radical engine combinations and requires port matching to fit most manifolds. Throttle bodies must be used with matching EGR plates. Gaskets are included. See Ford S/B fuel injection manifolds for 5L intakes
