FWIW to the 06-07 owners.....went to the dealership and they had no part # for the PCV (the parts guys are good guys too I knowem). Talked to my tuner on friday and he said that they really weren't an issue on the 2.5L because the system is routed differently.

The Knack. It's a rare condition characterized by an extreme intuition about all things mechanical and electrical ... and utter social ineptitude.
1. What is the year of the WRX?
2. This PCV valve looks different than the factory one. The factory appears to have two parts: a metal PCV valve and a plastic body with two ports.
I own a 2005 WRX with 50,000 and considering replacing the PCV valve, and clean MAF sensor/ Intake manifold/intercooler. Also, can I clean the intake manifold with the intercooler removed and run seafoam through the BOV valve hose? Any links for the things I want to do is appreciatted. thanks.
