Edelbrock Part # 3821 Performer Ford 5.0L EFI intake manifold is designed for 1986-95 5.0L V8 Mustang engines. The Performer 5.0 EFI aluminum intake manifold represents the standard for hot 5.0L performance. The modular design incorporates modern air flow technology and CAD programming for maximum power gains – up to 37 horsepower at 5500 rpm – with no loss of low speed torque. Features of the Performer 5.0 EFI manifold include: broad power range from idle to 5500 rpm; removable plenum cover that allows access to runners for modification; and base manifold is CNC port matched to upper manifold for maximum performance. The upper and plenum cover are powder-coated light titanium gray. The base is satin aluminum and not powder-coated. Combining the Performer 5.0 intake manifold with other Power Package parts gives you even more power across the entire rpm range. 1994-95 Mustangs engines require Throttle Body Adapter #3835.
