From my experience with it, for most people it will keep them out of trouble but if you do track the car or drive with a heavy right foot then an oil to air cooler is a worthy investment.

But for me and my quest for moar cool, i will be ditching the factory cooler for a 25 row oil to air cooler. I have the core, just need to fab the brackets and get the hoses made up.

Oil choice does play a big role in how much pleasure you'll get before things get flaccid though. Some oils take longer to heat up whether it be just characteristic or a sign of a better oil being that less engine heat must be due to less friction. I wasn't happy with the Nissan 5w30 we get here so now i'm using one of the local brands and it's the best i've used so far!
