Fixer,
ALL Cobras get the fix because ALL of them are messed up-- every 99 Cobra has the bad mufflers. (At least thats what SVT told me)
Not all have bad intakes though. But they use a process similar to "extrude honing" the intake, which Im sure definitely wont hurt anything on a Cobra actually making 320hp. They (SVT) have no idea (or so they claim) what Cobras are affected and what ones are not, so they just fix all of them.
Yeah, I really should go looking for C5's (maybe Ill get some 4.10s first
) and Ill definitely post what happens...
Steve
