The BMW M5 power and handling statistics are mind-blowing for a car tipping the scales at well over two tons. The S63 twin-turbo V8 is underrated by the factory and responds well to tuning and bolt-on modifications. Calling it the ultimate super sedan would not do this car justice; it’s just that good. But every amazing automobile must have an Achilles’ heel, right? Some investigation into this model told us that enthusiasts saw elevated oil temperatures during track driving conditions. Our team set out to create a replacement, high-performance oil cooler that could handle the rigors of extreme driving conditions and the abuse of daily commuting.

The Mishimoto S63 M5/M6 oil cooler features extremely precise CNC-machined billet-aluminum end tanks professionally TIG-welded to our robust bar-and-plate core. Our strategically designed 55mm-thick core provides a massive 24% increase in core volume and a 40% increase in external fin surface area. This added surface area promotes greater heat transfer, directly impacting internal fluid temperatures. Our performance oil cooler is a complete bolt-on solution that includes everything needed for an easy installation, such as hardware and replacement O-rings for the oil lines. Our heat exchanger is finished in a durable silver powder coat, providing corrosion resistance and improved aesthetics.

Whether your M5 sees frequent track time or just the occasional back-road jaunt, upgrading the oil cooler is a great way to extend the life of your S63 and ensure maximum engine output when you need it most. As with all our BMW products, this oil cooler includes our signature Mishimoto Lifetime Warranty.
