The catch cans will help in removing blow by oil during the combustion process that can get recycled back into the intake manifold.

Power steering fluid boils pretty easy. I switched over to Redline ATF D6 but it will still boil after long stints of hard driving. The cooler is just added insurance. I would keep an eye on yours. If you find it boiling after a few laps, then consider making changes (start with fluid then maybe a new cooler if needed).
