Mishimoto Oil Cooler, BMW S55

Add some much-needed durability and cooling power to your M3 or M4 with the Mishimoto 2015-2020 BMW M3/M4 Oil Cooler. True to form, the BMW engineers designed the M3/M4’s oil cooler with efficient space-use in mind. Suspended perpendicular from the rest of the cooling stack, this location utilizes the Bimmer’s aerodynamics in order to cool the oil, all while putting the lightweight, tube-and-fin cooler in harm’s way of road hazards.

Mishimoto made sure to beef up the entire oil cooling system design for the F8X chassis with their performance oil cooler. They ditched the lightweight design for a full aluminum, TIG-welded bar-and-plate cooler for added strength and cooling. The bars and plates are a much more robust form of heat exchanger core construction intended for improved heat transfer and have the strength to shrug off potential road debris, keeping your oil temps down and where it should be. Mishimoto also added 10 mm to the core’s thickness, equating in a 46% increase in core volume, and increased the oil capacity by .4 qt.

In addition Mishimoto wanted to add an extra degree of protection to the system by improving on the lines. From the factory, these vehicles are equipped with unforgiving hardlines that are prone to abrasion and corrosion damage. The Oil Cooler Kit provides a pair of application-specific, flexible, and robust nylon braided lines for a more secure channel for your M’s oil. Also included are their specially designed adaptors allowing for AN fittings from the S55’s oil pump and a secure connection to the oil cooler.

The Mishimoto 2015-2020 BMW M Oil Cooler Kit fits directly in place of the stock unit, and includes the Mishimoto Lifetime Warranty for a simplified and worry-free installation.
