Product Description

Your BMW S63 Twin-Turbo V8 demands serious cooling, especially in high-horsepower M5, M6, and M8 builds where oil temps can exceed 240 °F (115 °C). Stock oil coolers often crack, leak, and fail under extreme conditions, making an upgrade essential. Enter the CSF High-Performance Engine Oil Cooler, developed with CarBahn Autoworks to outperform and outlast the factory unit. Featuring a 33% larger 60mm core, three extra cooling rows, and 0.5-quart (0.47L) increased oil capacity, it ensures superior heat dissipation and engine protection. Unlike the fragile OEM Tube & Fin design, CSF rugged Bar & Plate core provides maximum impact resistance, while TIG-welded aluminum end tanks and CNC-machined connection blocks guarantee leak-proof durability.

With 75+ years of expertise, CSF is the go-to name for motorsports and performance cooling. Designed for F1X M5/M6 & F9X M5/M8 models, this plug-and-play solution installs seamlessly with minor trimming for optimal fitment. Finished in satin black for an OEM+ look and corrosion resistance, each unit is individually leak- and pressure-tested for reliability. If you're serious about pushing your BMW harder and keeping it running stronger, cooling isn't optional it essential. Upgrade to the CSF High-Performance Engine Oil Cooler and leave overheating behind.
