The idea is to condense oil vapor out of the CCV system before it makes it into the intake, based on the theory that the intake clogging happens due to hot, sooty EGR gasses and cool, oily CCV gasses combining and forming 'sludge'.
So theoretically, it helps prevent intake clogging. There is no performance benefit, and I think it's not 100% proven that this will prevent intake clogging. I've recently heard a competing theory that it's really bad MAF performance that results in intake clogging...
Last, I dunno if PDs suffer from this issue anyway.
