Topic: upgrading your factory p/s & coolant tanks?

I think going to go with the 3x10

yeah, should be fine - I remember now that I had to go with the skinny one to clear the inlet pipe to the intercooler so I didn' have a choice. I suggest maybe getting an even longer one, no harm in that but there's a problem if you don't have enogh expansion (fyi 2x19 is larger volume than 3x10)

Yeah i filled the factory bottle to mid level and it was 45 oz. I dont have room for anything that big in the space i used. But interesting enough the 3x10 is rated at 32oz and the 2x19 is only 23oz. Must have to do with the height of the overflow tube in the bottle.

Why not just go with a complete unit rather than the remote reservoir?

i'm super cheap, spent $8 on mine. Junkyard had 50% on a holiday week.

FYI both those tanks have integrated filters and are considered service items,
you can buy them online new for like 23 dollars. 
The filter is good for about 12000 miles depending on your driving habits.

Sorry was distracted from the web for a while,, yep on a BMW you
throw the whole reservoir away when you service the system.
They are cheap to buy, hate the waste though. Pelican parts is where I get mine.
I find by 12K that the filter is shot, I've dumped the system and
refilled and the fluid turns black almost instantly.
They hold so little fluid a cooler is mandatory. BMW's don't use
power steering fluid they use Type F auto transmission fluid. (Trivia :) )

I'm swapping out the throwaway unit for a aftermarket AL tank with a spin-on filter.
My car is AWD and works the heck out of the power steering.
