Just finishing off the intercooler piping for my rb30 and noticed i have forgotten to add in a piece for this pipe. (in pic)
Not 100% what it does but its a breather of some sort.
Can you please tell me what it does for starters, and whether its 100% essential to have this routed into the intercooler piping?
This isnt a pic of my setup, rather one recycled from here, so thanks for the pic
Have put a pic of my cooler pipes for interests sake.
