CSF High-Performance Engine Oil Cooler BMW M5 (G90/G99) / M8 (F91/F92/F93) / M5 F10 / M6 (F06/F12/F13)

Today, many M5s, M6s, and M8s are producing well over 1000hp - but with increased power comes increased heat, and BMW's factory oil cooler is a genuine weak point once you push past stock. Some owners report oil temperatures exceeding 115°C on hot track days, which isn't just a performance concern - sustained high oil temps can trigger limp mode and, in extreme cases, lead to catastrophic engine failure.

 Beyond the extra cooling capacity, this addresses a second, less obvious problem: the factory oil cooler sits in a genuinely vulnerable mounting position, and many F1X/F9X owners have been forced to replace it after leaks or impact damage - a problem that gets worse with lowered suspension setups. CSF's bar/plate design core is 33% larger (60mm) than stock, increasing oil capacity by 0.5 quarts (0.47L), with cast end tanks and 100% TIG-welded construction for genuinely rugged durability where the OEM all-metal design has known weak spots.

Works with: S63 and S68 twin-turbo V8 engines - true plug-and-play, drop-in fitment using OEM-style inlet/outlet connections.
