Wagner Tuning Competition Transmission Oil Cooler Kit – BMW M3 / M4 (S58 G8x)

OVERVIEW

The Wagner Tuning Competition transmission oil cooler kit is built to keep transmission oil temperature in its optimum range on the BMW M3 and M4 G8X with the S58 engine, even under sustained load. It is aimed at owners who track their car or run elevated power levels, where the stock cooler runs out of capacity.

Wagner increased the frontal inflow area by 81.6% and the mesh volume by 93.6%, so the cooler dissipates far more heat and holds oil temperature stable under high load. Keeping the oil in range keeps oil pressure stable and extends transmission service life. The kit is a plug-and-play design and installs quickly.
