Don't really want this thread to turn in to a VTA & recirculating dump valve debate, there are plenty of those on here already.
However, i'm just wondering if anyone knows what size bung would be needed for a 2004 wrx wagon off the top of their heads?
I know i could go out in the freezing cold & check but i can't be arsed, its Sunday & freezing outside. :loll:

Any help would be great. Thanks.
