Ford Racing 4.6L Performance Improvement (PI) Intake Manifold

These 4.6L Performance Improvement (PI) intake manifolds from Ford Racing are the current-production plastic manifolds used in 2001-03 4.6L SOHC 2V Mustang GTs. They are a less-expensive alternative to aftermarket performance intake manifolds for PI head swaps, and they are great for custom engine builds.
