Mishimoto BMW S58 Engine Oil Cooler Kit - Direct-Fit Uprated Bar-and-Plate Aluminium Oil Radiator/Heat Exchanger for G80 M3, G82/G83 M4, G87 M2 (2021+, Comp & xDrive) - 41% Larger Core, Heavy-Duty Track-Ready OEM Replacement

Uprated Engine Oil Cooling for BMW G80 M3, G82 G83 M4 and G87 M2

Push your S58-powered BMW harder for longer with this Mishimoto high-capacity engine oil cooler kit. Designed as a robust, bolt-on replacement for the factory unit, it delivers significantly improved thermal control for fast road, track day and spirited driving while keeping OEM-style fit and finish.

Why this cooler belongs on your S58

The stock tube-and-fin heat exchanger sits low and takes a beating from stones, kerbs and road debris. Mishimoto upgrades you to a heavy-duty, all-aluminium bar and plate construction that shrugs off abuse and sheds heat more efficiently. Core volume is expanded by 41 percent and core thickness increases by 35.7 percent to help maintain stable lubricant temperatures session after session.

• All-aluminium, TIG-welded assembly with CNC-machined end tanks for long-term reliability
• Up to 41 percent more core volume for greater heat rejection and temperature stability
• 35.7 percent thicker core to combat heat soak during repeated hard laps
• Bar and plate architecture for excellent durability and pressure tolerance
• Keeps factory seals, undertray deflectors and bash guards so airflow and protection remain as BMW intended
• Supplied with the fittings and hardware required for a straightforward install
• Covered by the Mishimoto Lifetime Warranty

Vehicle compatibility

Suits BMW models with the 3.0 twin-turbo S58 engine: M3 G80, M4 G82 and G83, plus G87 M2. Works with standard, Competition and xDrive variants from 2021 onwards. If you are unsure about your chassis or build date, contact us and we will confirm fitment before you order.
