do88 Gearbox Oil Cooler BMW M2/M3/M4 (G8X) Enhance the performance of your 2021 BMW G8X M2, M3 or M4 with the do88 Gearbox Oil Cooler. This part is designed to maintain optimal transmission temperatures, especially during demanding driving conditions. Background The BMW G8X models feature a ZF 8HP automatic gearbox, which is known for its speed and strength. It is built to cope with the high power of the S58 engine. However, when you upgrade your engine with additional performance components or a tune, the stock cooling system may struggle, particularly on the track. Overheating can lead to slower gear changes and, in severe cases, damage to the transmission. Our Solution The do88 performance transmission cooler significantly boosts cooling efficiency. Our engineers have redesigned the core of the cooler, increasing its volume by 71% and the cooling surface area by 50% while keeping oil pressure similar. We use harmonica tubes with internal channels, ensuring optimal cooling efficiency. This design raises the cooling capacity with a 42% increase in oil volume. Key Features Core volume increased by 71% and active cooling area by 50% compared to the original cooler. Harmonica tubes promote optimal oil flow and maximum contact with cooling surfaces. OEM-style “Quick Connect” inlet and outlet connections. Drop-in fit with no modifications required for installation.
