Fall-Line Motorsports G8X M2 / M3 / M4 Oil Cooler Guard

The G8x M2, M3, and M4 cars are incredibly well sorted from a cooling standpoint. Even in a road course environment with extremely high ambient temperatures, the S58 engine tends to operate beautifully, with consistent oil and water temperatures. BMW M invested a great deal of time, money, and effort into designing a cooling system that worked in nearly every condition that the M2 and M3 / M4 would be tested in. Although excellent ducting, good core design, strong fans, and other factors all play in to how well a cooling system works, there is one ultimate factor which cannot be circumvented- you must have enough heat exchanger surface area, and you must have enough heat exchangers. When examining the front of a G8X, then, we see the hard work of the M engineers in packaging the various cooling components of the car. Everything had to be accounted for, and given ample space, surface area, and ducting. Unfortunately, this leaves the S58 engine’s oil cooler precariously exposed with no p
