Description
The Mishimoto MMOC-F10-12SL is a purpose-built performance oil cooler engineered specifically for the BMW S63 twin-turbo V8, the engine that powers the M5, M6, M8, and M850i. Mishimoto’s team designed this cooler after seeing enthusiasts report elevated oil temperatures during track driving, and the result is a robust bar-and-plate replacement built to handle both extreme track sessions and daily commuting without flinching.
This Mishimoto cooling upgrade centers on a 55mm-thick bar-and-plate core that delivers a 24-percent increase in core volume and a 40-percent increase in external fin surface area compared to stock, promoting greater heat transfer and more stable internal fluid temperatures under load. CNC-machined billet-aluminum end tanks are TIG-welded to the core for durability, while precision-machined AN-flare inlet and outlet fittings (male on both sides) are designed to prevent leaks. The entire assembly is finished in a durable silver powder coat for corrosion resistance and a clean appearance, and it ships as a complete bolt-on kit with new OEM-quality O-rings, mounting bracket grommets, and M8 x 1.25 oil line bolts so installation stays straightforward.
Vehicle Applications
This oil cooler is built to fit the BMW M5 Base across 2013–2016, 2018–2023, and 2025, along with the M5 Competition (2019–2021), M5 CS (2022), M5 Edition 35 Years (2020), and the M5 Touring Base (2025).
