I was wondering if anyone has any suggestions for a cold air intake for a 2004 GT. I have been looking at the Steeda GT High-Flow Air Kit, and at the MAC GT 85mm Mass Air System. I have heard that an after market intake can cause prolems with your engine warning lights and such. Steeda claims that their kit won't cause the warning lights to turn on. Anyone have any suggestions betweeb these two kits, or any suggestions for another brand? The car is a show car more than a race car, and I'm looking for an intake to more or less dress up the engine. Thanks.
