The Performer 5.0 RPM II manifold for 1986-95 5.0L Mustang engines has shown significant gains in horsepower over existing designs in the 1500-to-6500 rpm range, and is ideally suited for street and strip applications. This manifold consists of a V-shaped crossover with an increasing cross-sectional area, which passes over to eight large tapered runners. Will work with stock fuel rails. Our 70mm throttle body is recommended (75mm will require port matching). 1994-95 Mustang engines require Throttle Body Adapter #38353 and Adapter Kit #8025. May not fit with stock hood of 1994-95 Mustangs, aftermarket hood recommended.
