Dead serious question...catch can. so many vids on pros and cons. looks like a bitch fyi project and.... are they needed? And if so why didn’t VW design it with one ?
I'm gonna try to explain it as I understand this. Like many other manufacturers VW intends for their cars to be left stock. Once you start stacking tunes the is more and more junk that gets clogged up in the system. The catch can helps to separate the loose particles that the PVC system can't keep up with. VW doesn't design one because with a stock engine you don't need one.
