Does anyone know if the '03 Cobra lower intake will fit my '94 Mark VIII? A buddy wants to twin-turbo his '03 and I could get the Cobra stuff(lower, compressor, MAF, possibly injectors, intercooler(s), and coolant tank, etc., etc.) for cheap money.

Any information you could provide would be greatly appreciated.

Good Day

Nope, different heads.

The ports on the heads are totally different. If you want to run the newer stuff you need to change heads over to the 'C" style, heads should cost you about 1500 smackers ready to go then you have to get the intakes etc.
Hope this helps, good luck with the project.
