hey guys just got done buying a New 08 Mazda5 GT galaxy gray traded in my 06 touring carbon gray. Wanted to ask some questions with the GT has the HIDs but I dont like how they are and with my 06 I had Aftermarket HIDs, will it hurt to put the aftermarket HIDs over the factory HIDs because I like the aftermarket more than the factory. Where is the tire pressure gauge located or does it come on when the tire pressure goes low? Will post pics soon. (rockon)(yippy)(cabpatch) TIA.
