If you own a 1996-1998 Mustang GT, you are well aware of the horsepower deficiencies of the 4.6L 2V under the hood. Luckily, starting in 1999, Ford corrected some of those issues by way of "Power Improved" cylinder heads and intake manifold. Even better news is that these PI heads and intake are a nearly bolt on swap for your 1996-98 Mustang GT!
This kit includes virtually everything you need to make the swap to PI Heads from the heads and intake, all the way down to gaskets. The PI heads used in this kit come from FRPP and are the 2001-04 design. They come loaded with valves, springs & stock cams. The PI intake has the aluminum coolant crossover that must be drilled & tapped to accept the coolant temp sensor.
