BMW M5 (E60) / M6 (E63/E64) High-Performance Oil Cooler

The S85 V10 is an extraordinary engine - quite possibly the only V10 we'll ever see in a production BMW - but it comes with a genuine cooling challenge. Oil temperatures can spike to dangerously high levels during performance driving, compounded by a factory oil cooler that's prone to leaking and cracking at several known weak points, particularly around the feed and return lines.

CSF's Race-Spec design addresses both problems directly. The fragile tube/fin core is replaced with a robust, durable bar/plate design that's 40% larger than the factory unit, with two additional cooling rows and a significantly thicker core (63mm vs the OEM's 45mm) for genuinely superior cooling capacity. A solid line connection block reinforces the historically weak feed point, and the return tube is braced for real strength - while fully TIG-welded end tanks replace the factory's weaker brazed construction for a much stronger overall connection.

Why Choose This Oil Cooler

• 40% larger core than the factory unit - two additional cooling rows, 63mm thick core vs OEM's 45mm
• Robust bar/plate design - replaces the more fragile factory tube/fin construction
• Reinforced feed and return lines - solid connection block and braced return tube address known OEM weak points
• Fully TIG-welded end tanks - genuinely stronger than the factory's brazed construction
• Essential for supercharged or track-driven S85s - added power brings added heat, and this is built to handle it
• Preventative maintenance upgrade - helps avoid costly repairs as these cars age
