Oil Cooler install solves the problem?

I'm not seeing what function relevance of all those plastic covers either other than cosmetic. What will manufacturers do in the future? Seal off the whole engine compartment and have a few holes for fluid fills and dip sticks. I'll bet they've thought about it.

Have you seen under the hood of a Cayman? Porsche is already doing it!

It helps isolate the heat of the engine bay from the battery and brake fluid. Not much, but it does. Many cars have this, including my Mercedes E320. The only difference is with the Mercedes it has seals and the hood acts as the cover, so it's not as obvious. But it still isolates the hot engine compartment from the brake systems/battery (or in the case of the Mercedes, the electronics - which are put where our batteries are in the Z). I'd bet it reduces temps in these areas at least 10-20*F. Cooking your brake fluid is not a good thing, trust me.. I know..

I popped plastic covers and looked again. From what I could see those compartments are sealed fairly well with sheet metal forming the sides and bottom. I did see what appeared to be a drain hole. So I guess it was Nissan's intention to seal them off rather than simply drop a plastic cover on top. Ok +1. Still seems like you'd get heat build up. I could be a geek and measure inside vs. outside temps.
