CSF High Performance Engine Oil Cooler - BMW F1X M5 M6, F9X M5 M8

Product Details

CSF has been at the forefront of pushing the performance limits of the S63 engine with its Twin Charge Air Coolers. Today, many M5, M6, and M8 models are exceeding 1000HP, but with greater power comes increased heat. As power levels rise, so do oil temperatures, with some owners experiencing temperatures surpassing 240°F (115°C) during intense track sessions. As these M cars continue to age and power thresholds are pushed further, factory cooling systems are struggling to keep up.

To address this challenge, CSF partnered with Carbahn to develop a direct-fit solution for both platforms. Engineered to manage the extreme heat generated by Carbahn’s new S63 Stroker Kit, this oil cooler is designed for peak performance and reliability.

But enhanced performance isn’t the only reason to upgrade. Many F1X and F9X owners have had to replace their oil coolers due to leaks and damage, primarily caused by their exposed mounting position—a problem worsened by lowered suspension setups. A stronger, more durable design was needed to resolve these issues.

Whether your M5, M6, or M8 is a daily driver, weekend cruiser, or dedicated track machine, upgrading the oil cooler is a smart investment. Tuned S63s, especially those with upgraded turbos, produce significantly more heat, making efficient cooling even more critical.

Excessive oil temperatures can quickly trigger limp mode and, in extreme cases, cause catastrophic engine failure. CSF’s new High-Performance Engine Oil Cooler isn’t just about optimizing performance—it’s a preventative upgrade that helps avoid costly repairs and extends your engine’s lifespan.
