Car is US spec. I bought it while I was working in DE. No other performance mods. I'll see what I can do this weekend with my iPods video camera and mic for you guys.

Do you have any other engine mods? exhaust mods?
Just curious, your account list you as in the EU (Germany) if that is the case, then why would your E90 be originally equipped with the USA/North America air box? If you are in Europe wouldn't it come stock with the Euro Airbox?
