Hey,

I have an 04' STI, will the 04' WRX fog lights fit the OEM STI bumper without any modification?

Should. If you get no reply call your local dealer.

Yeah. MY for MY you shouldn't have any problems. Wiring.... That's a different animal altogether but you should be able to make it work without a lot of hassle.

Yeah, the wiring I can figure out. Since the fuse box is the same, I'll add a fuse for the fog lights and connect it from there. But is the fog light cover (from STI) and the fog lights (WRX) the same size and shape?

Yeah, year for year they're the same.

I know they'll work because a lot of folks have used the fog light insert, or plastic cover piece, to create a sort of ram jet type intake for thier CAI. It looks a little odd but it lets a lot of fresh air into the CAI.

End random info...

your just going to have to installl the brackets that hold the fog lights. i don't think they will be on the sti bumper. but if your buying them make sure you get the brackets with them.
