@Anti. All thoes horror stories about Mobil1 are true! It's SUCH bad oil its not even funny. Before I even bought my STi, I did so much research on which oil to use. Bobistheoilguy.com is the best forum for car oils lol. Sounds funny, but the information on that site is amazing.
@itZj0k3r. Yea, any time you put anything on a suby you NEED to tune it. If you throw even an intake on it, it will run like shit. Subaru's have a MAF sensor, you throw a random intake on there without telling the computer what to be expecting for airflow readings and its going to be sending the wrong amounts air into the engine. Sounds crazy but its true.
If you guys have or are getting into subys, id check out NASIOC.com. The biggest place for any information on any subaru. For your fluids as mentioned before, check bobistheoilguy.com/
