bulb size?

[high3at0209]

looking to putting HIDs, im not sure which bulb size it is, i think its H7, is this right?

Yes, H7s are the bulbs for the MS3s that have halogen bulbs (Sport trim). But if you have a GT trim MS3, you should have HIDs already?

Might want to read up on this thread about converting halogens on the MS3 to HIDs. DDM Tuning sells them for $30 + shipping these days:
