Anyone know the part number for the intake/supercharger for the 4.4l and the injectors

I am hoping you aren't considering the installation of a "V" Supercharger on your unmodified "X" motor. There is LOTS of stuff that is different inside the moter including the pistons, heads, rods--etc...

I will recommend again that you contact D3 performance to discuss your lans and budget. They can advise you on how to best obtain the maximum benefit for your dollars.

Regards.
