I recently addressed an issue that I had with my spark plugs fouling out quickly, and it turned out that the cause was a hole drilled in the BPV recirculating hose for a poor man's blow-off sound by the previous owner. It's a 2006 WRX, no mods yet.
I ended up having to change out the turbo inlet (blast that darned nipple that goes from the recirc hose to the inlet), and had to detach a number of vacuum hoses. I'm fairly confident in where they all go, but would like to make sure. Does anyone have a good top-end picture of a stock '06 or thereabout engine? Thanks for any help.
