If your car is lowered, we recommend adding protection to your engine with one of our BMW skid plates, especially If your car has any low hanging critical components like an oil cooler. We make all of our skid plates from thick aluminum for maximum protection.
The G8x 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. Although excellent ducting, good core design, strong fans, and other factors all play into how well a cooling system works, there is one ultimate factor that cannot be circumvented- you must have enough heat exchanger surface area, and you must have enough heat exchangers. A direct impact on the oil cooler can have catastrophic effects, draining the S58 of all of its oil in seconds, a fact that more than a handful of previous generation M3 and M4 owners have had to learn in a painfully direct way. When examining the front of an M3 or M4, 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 protection.
