I have a 1994 cobra. normal bolt-ons and a some kind of cam. {bought the car with the cam in it dont know what cam it is} my question is does a OEM 94 cobra have a different(bigger)MAF than a GT or is it the same? second i ask what size or brand should i go with? what size is stock cobra/GT MAFS? Have any of you guys noticed a difference after boolting one on.
