You're very welcome guys. I've benefitted a lot from many great DIY's on this forum, so it's nice to be able to contribute also.

I "think" there was a change in both (seemed a little smoother) but I am always hyper aware of the potential for placebo effect. So for me it is more about having a revised part which hopefully means improvements were made from the original, and one which should last for many years.

Regarding the part revision; I still suspect the new part may be designed to operate at higher vacuum, but this is yet to be proven (see thread here - https://rennlist.com/forums/997-foru...-resource.html

I've read all the horror stories about AOS failures (specially 997.1's) and seek your advice as to the wisdom/need/propensity/peace-of-mind that my changing it would bring.
I think Master provided some great insight in his post. I also think the membrane like any similar part will lose it's properties (particularly flexibility) over time and not just based on miles. If you don't mind a bit of DIY, this is a great project for a rainy afternoon or evening, and a very cheap update.

Anyone know where to pick up an AOS(air oil separator) for 997.2 (2009 Carrera2) besides the dealer?
