I have a WRX wagon on the way and I hope to get it in about three weeks... it will be my 10th Subaru, by the way. I want to be ready for a couple instant but small mods. Does anyone know:

1. what headlight bulbs are used?

2. Is the air filter the same as the '03?

3. Does the '04 wagon have the same sway bars as the "04 sedan, or is the rear one smaller in diamteter?

Thanks for any help... see you on the roads of Long Island's north shore soon.
