Turner Motorsport F8X High Performance Oil Cooler

If you're pushing your S55-equipped BMW to the limit, keeping it cool is crucial. While most enthusiasts focus on upgrading the radiator and water-to-air intercooler systems, the engine oil cooler is an overlooked yet critical component.

New for the F8X-generation M2, M3, and M4 is a low-slung, horizontally mounted oil cooler that leverages aerodynamics to create a low-pressure zone, increasing the overall efficiency of the oil cooler. While this design offers sustainable oil cooling for street-driven vehicles, the undersized core quickly reaches its limit on modified or track-driven cars. Additionally, its exposed position leaves it especially vulnerable to damage from road debris, meaning a small scrape can necessitate full replacement. If you're already replacing your oil cooler, why not upgrade?

Turner's team of engineers set out to improve upon the factory design by engineering a larger core that restores lost efficiency and offers measurable improvements in thermal performance. By increasing the core thickness by 7% over the factory unit, this upgraded design improves airflow efficiency through the cooler, helping maintain lower and more consistent engine oil temperatures. What's more, its robust bar-and-plate core design, sheet metal end tanks, and 5052 aluminum composition, this cooler is built to take abuse. Whether you're replacing a tired OEM unit or upgrading for peace of mind, the Turner Motorsport High Performance Oil Cooler is a must-have reliability upgrade for your F8X BMW.
