Application. This Ford Racing Performance Improvement (PI) Intake Manifold is a direct fit on 1999-2004 4.6L GT Mustangs with PI head ports. It can also be used on 1996-1998 4.6L engines with PI heads, with additional parts and modifications required.
Technical Note. 1999 and 2000 GT Mustangs will require the use of an alternator bracket from a 2001-2004 GT. All Mustangs will require a new factory style manifold to head gasket and a thermostat gasket.
