How hard is this to do? I'm thinking about doing it because I hear a lot about how much better shifting feels. But I've never worked on cars until I got my WRX. I've only changed the oil once myself, but plan on doing it regularly since it's warm out now. I'm just afraid to screw something up.
I read the in depth tutorial on scoobymods, and it seems easy enough. Only thing I don't want to do is take off the intercooler, if at all possible. I hear it's a pain in the ass and I don't want to screw it up.
When replacing the drain plug, how tight do I tighten it? Do I just tighten it as tight as I can? Or a certain torque?
