The S54 is an incredible feat of engineering. Smooth power delivery, individual throttle bodies, and an 8,000 rpm redline makes for an unforgettable driving experience. As with any BMW, maintaining optimal oil temperatures is key to extending the life of your vehicle and ensuring that you’re getting a driving experience rivaled by very few other vehicles on the road. As many of these vehicles see frequent track time, the team at Mishimoto felt a need to develop a performance oil cooler kit that would not only provide improved durability, but also deliver the efficiency needed for track driving. Our team of engineers developed an extremely efficient core that provides a proven 30 Degrees Fahrenheit (16.7 Degrees) drop in oil temperature. With an increase in core thickness of 110 percent, this oil cooler kit increases your oil capacity by 0.44qt. The oil cooler one piece billet end tanks have been designed for maximum reliability, giving you the confidence you need to push your E46 M3 to the limits.Direct fit for 2001-2006 BMW E46 M3
