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.

Adorable and Snug
Color: Dark Grey, Size: Zippered 13x18 Inch (Pack of 2)
They fit the toddler pillows perfectly! Zero shrinkage in the wash and hasn’t held any stains. The color looks rich and hasn’t faded. Very soft and the zipper closure doesn’t stick out at all! Will buy more!

Inexpensive and Nice Quality
Size: Standard (Pack of 2), Style: Medium, Configuration: Hometextile
I was hoping there would be more of a firmness to these pillows, however they are more soft than I was expecting them to be. Id recommend these pillows for someone who wants a fairly non firm pillow.
