Hi,

Needswings sells an awesome split cooling (intercooler separation) kit consisting of a couple of houses and I get the concept. But I have seen many folks on MBWorld actually use BMW power steering reservoirs or come up with other solutions to have a separate cooling reservoir.
Are bot equally effective or is one better than the other at cooling temps? Also I don't see a lot DIY instructions for both. How difficult are they to install?

I'd love to hear an honest comparison and a source for a DIY.

Thanks guys!
