Some advice please.
Having fitted an Eaton M45 to my 2002 MK2.5 1.8 I am unsure as to what is the "correct" way to apply a breathing system to the hotside of the cam box.
Use a "mini" filter & vent into the atmosphere?
Use a rubber hose & attach to the air intake hose after the MAF?
I have seen examples of both systems.
Which is the best system & why?
Thank you for looking
