Yeah the oil looked pretty dirty, I'll send it off for a Blackstone report.
I should probably clean and oil my air filter soon.
Car has been great, no problems, I've had it since day one in 2010.
I haven't heard of very many STI owners using anything but the OEM filter. The whole 23 psi bypass thing. I have come across a couple alternatives but I still have 3 more of these left.
