So I've replaced my
AOS
with a genuine
Porsche
model and the oil going into the intake has been drastically reduced. I figured I'd take it further and replace the two hoses that attach to the
AOS
and I found some interesting things.
The bottom hose requires removal of the back half of the intake. It also terminates in the drivers side front of the engine bay so taking off the front engine panel is mandatory. It is a very tight squeeze but I somehow got it out and back in.
Check out this video of how crispy my lower
AOS
hose was, man this is bad.

I suspect EU standards are part of the reason but across decades of continuous
Porsche
ownership I have found their polymers to be sub standard. Often the failures were of items that would be an oddity to replace on other brands.
To be fair to
Porsche
, my car does have 97,000 miles on it. I think when you approach 100,000 miles you have to expect to change some things cause they are just getting old.
I too just changed out my
AOS
on a 2010 987v2
Boxster
, I ordered #3, #4 and #10, Parts 99970731641, 9A110752001 and 9A110751501 before I began, very brittle indeed, those quick disconnect ends after they get old always break, I was prepared.
Quick follow up, car threw code P0444 when I tried to drive to work this morning so I took the Toyota. Got home, checked the code. Turns out I unplugged a plug under the drivers side intake assembly somehow. Quickly found the plug and the socket and plugged it back in, cleared the code and everything is awesome. My car seems extraordinarily happy after this, could be a placebo, but I swear it seems to run better than ever.
Soda: Parts cost only repairs, intake cleaning,

power air filter and other tweaks have been clinically demonstrated to double torque and HP on our factory proprietary dynos. Why I remember when single arm
spark plugs
could be indexed with added washer kits to direct the open area of the plug spark within the combustion chamber. It's those little edges that brought home the trophy for Tom Slick and his thunderbolt grease-lapper.
