WRX_STi_PPP

I believe that looking at the ECU is a way of telling...should have a sticker on it. you could always contact subaru/prodrive and give them the chassis number to look up perhaps.

Hello all...just a "Hi" from a new member. I have an 05 STi PPP which is my third scooby now...a classic and two newage. Look forward to being an active member...Cheers!
