Mishimoto S55 Performance Engine Oil Cooler / Oil Radiator Upgrade – BMW M3 F80, M4 F82 F83, M2 Competition F87 (2015-2020) – Direct-Fit Bar & Plate Aluminium Heat Exchanger, Bolt-On Track Cooling – MMOC-F80-15

MMOC-F80-15 Uprated Alloy Oil Radiator for BMW S55 F-Series M

Keep oil temperatures in check on fast road and track with this heavy-duty bar and plate alloy oil radiator. Designed as a true bolt-on replacement for the factory tube and fin unit on S55-powered F80 saloon, F82 and F83 M4, and F87 M2 Competition, it provides greater heat rejection, increased core volume and extra oil capacity for consistent lubrication control under sustained load.

We have fitted this cooler on customer S55 cars at MJ Modifications and the feedback has been excellent. Owners report rock-solid oil temps during spirited drives and track days, with the added confidence that comes from a tougher, TIG-welded construction and a lifetime-backed product.
