DO88 S58 Engine Oil Cooler G8X M3 M4

Upgrade your G8X M-car’s oil cooling system with the do88 Performance Engine Oil Cooler – a robust, all-aluminium Bar & Plate design that improves thermal efficiency and durability. Engineered to prevent oil leaks caused by stone chips and overheating, this cooler is a critical upgrade for anyone driving hard on track or running higher power levels.

Stock Cooler Vulnerabilities

The factory S58 oil cooler is a lightweight Tube & Fin design mounted horizontally beneath the front radiators – leaving it exposed to road debris and stone chips. Damage here often leads to oil leaks that can have catastrophic consequences for your engine. The OE design also struggles with high oil temps during extended track sessions or aggressive driving.
