01-06 BMW E46 M3 Mishimoto Oil Cooler Kit

Model: MMOC-E46-01

The S54 is an incredible feat of engineering. Smooth power delivery, individual throttle bodies, and an 8,000 rpm redline make 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 an unparalleled driving experience. As many of these vehicles see frequent track time, the team at Mishimoto decided to develop a performance oil cooler kit that would not only provide improved durability, but also deliver the power needed for track driving. The result: an extremely efficient core that provides a proven 30°F (16.7°C) drop in oil temperature. With an increase in core thickness of 110%, this oil cooler kit increases your oil capacity by 0.44 qt. The oil cooler end tanks, cast from a single piece of aluminum and TIG-welded to the core, have been designed for maximum reliability, giving you the confidence you need to push your E46 M3 to the limits.

This oil cooler kit is designed as a complete bolt-in fit, requiring no modification to work with the stock radiator or the Mishimoto BMW E46 Performance Aluminum Radiator. To ensure a complete direct-fit, Mishimoto engineers have designed a fully CNC-machined 6061 aluminum and 303 stainless steel BMW E46 Oil Line Fitting Kit, which makes the removal of the stock hard lines and installation of stainless steel braided lines a simple task. This kit includes preassembled stainless steel lines with -10AN fittings to help direct the oil to and from the cooler, as well as a black Mishimoto Oil Line Stay to keep your lines from rubbing. As with all our products, the Mishimoto E46 M3 Oil Cooler Kit includes the Mishimoto Lifetime Warranty, ensuring superior product quality and craftsmanship.
