Is having an oil cooler in cold temperatures a known problem? Is the plate more of a "must have" thing if my Z is my daily driver?

(I get so frustrated with Nissan sometimes! Make a sports car that can't be tracked without overheating, then the fix to that needs another part because I live in a place that has winter...grrr...)

Thanks!
