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 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. When examining the front of a G8X, 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. 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.

Having seen that this was a critical need for both the M2 and M3 / M4 cars, IND worked with Fall-Line Motorsports to develop a robust oil cooler guard specifically designed to shield the S58’s oil cooler from large road debris and prevent disaster.

The new Fall Line Motorsports oil cooler guards will be constructed from thick stainless steel plate and will fasten directly to existing frame members on the G80, G82, and G87 cars, spreading any impact across strong structural components. Special care was taken to ensure that the opening in the oil cooler guard matched the shape and size of the existing BMW oil cooler air outlet, ensuring that proper airflow was maintained.

NOTE: The FLM Oil Cooler Guard is not a direct fit for cars equipped with the CSF Oil Cooler Part# 8266.
