CSF 8317 High-Performance Engine Oil Cooler for Select BMW 2012-2026 (M5/M6/M8)

Fits select 2012-2026 BMW M5, M6, M8, and M850i xDrive (including Gran Coupe, Competition, and CS models).

While the factory BMW oil cooler features an all-metal design, it possesses inherent weak points that can lead to failure under high-performance driving conditions. The CSF 8317 High-Performance Engine Oil Cooler is engineered to address these vulnerabilities using a heavy-duty bar-and-plate design for superior heat dissipation and rugged durability. Developed in collaboration with CarBahn Autoworks to manage the extreme thermal requirements of their S63 Stroker Kit, this cooler is a vital upgrade for high-output BMW engines.
