Hello there, I am new to this forum. I just purchased a 2007 wrx wagon. In the past I have owned 2x 2003 wrx models. A silver and a blue one. I usually do not join forums do to past experiences where I have been treated bad,but this forum seems to have nice people who are friendly. Not the type who tell you how stupid you are for any question you ask and then go on to tell you how awesome they are. lol. I do not claim to know everything but I have a tech background a lot of tools and a paint booth at my house. I am a decent mechanic, but will always have more to learn. Anyway here is my simple question. I am looking at cold air intakes and a few exhaust systems. Do the sedan parts work on the wagons and are all 02-07 parts interchangeable. Ty in advance. Sorry if this has been covered before.
