An oil cooler is a critical upgrade if you plan on doing any spirited driving for a period of time. Without it, the oil becomes heat soaked and unable to properly lubricate the engine. Then the car goes into limp mode at about 280F cutting the fun and reducing the rpm limit to around 3500. Putting an oil cooler on will give the oil the cooling capacity it needs to prevent limp mode and keep your engine protected. The larger the oil cooler, the higher cooling and oil capacity the engine has. There is such a thing as oil being too cool, so be sure to purchase a thermostatic plate to maintain good operating temps while driving. The target temps for our engine is between 180F and 220F. If you exceed those target numbers, fret not, it's not the end of the world, just be aware of your weather conditions and driving habits when it is.
