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.

Worked great in Italy!
Color: White/grey-Type L
Used them on our recent 7 day trip to Italy. Every hotel had the 3-prong outlet so these were perfect. Charged up all our phones, iPads, and used them to convert to 120V for other appliances. Highly recommend!

Perfect travel device for travel in Italy!
Color: White/grey-Type L
We traveled all over Italy and these worked perfectly everywhere. All the ports were helpful and reduced the number of adapters we needed. We brought a 2-prong style as well, that had larger posts and was supposed to be equally universal but it was definitely not. I would definitely recommend this to anyone and recommend you skip the 2 prong style. The only other consideration is that when you unplug a lamp or something else to use the plug then you may want an additional way to plug the lamp back in and the additional US outlets on the side won’t help, since the lamp will the the same European 3 prong plug. That would definitely be a bulky adapter, but might be worth having one in the group.
