Add some flexibility to your S55's oil cooling system with the Mishimoto Oil Cooler Line Kit for the 2015-2020 BMW F8X M3, M4, and M2 Competition. These M cars are equipped with a set of unforgiving hardlines routing from the cooler to the oil pump from the factory. These lines are prone to corrosion and abrasion over time, leading to leaks and improper lubrication of your might S55. The Mishimoto kit allows you to replace these factory lines with a set of application-specific, robust nylon braided hoses, complete with -10AN fittings, that are ready to stand up to the harsh conditions found under the hood of your Bimmer. Our kit also includes all of the necessary hardware to adapt these lines to your BMW. First, our oil line fitting kit adapts the oil pump housing for the use of -10AN fittings with our blue anodized, full aluminum adaptors. Also, we also include a second pair of adaptors that allow our new lines to attach to either the stock oil cooler or the Mishimoto bar-and-plate oil cooler securely. The Mishimoto Nylon Braided Oil Cooler Line Kit for you F8X M cars is available in a stealthy black to retain an OEM+ look under the hood and includes the Mishimoto Lifetime Warranty for a worry-free installation.
