The Mishimoto Nylon Braided Oil Cooler Line Kit replaces the unforgiving factory hardlines on the 2015-2020 BMW F8X M3, M4 and M2 Competition (S55 engine), which run between the oil cooler and oil pump and are prone to corrosion and abrasion over time, leading to leaks and improper lubrication. This kit swaps them for application-specific nylon braided hoses with pre-installed -10AN fittings, plus all the adapter hardware needed: blue anodized aluminum -10AN adapters for the oil-pump housing and a second pair of adapters to attach the lines to either the stock oil cooler or the Mishimoto bar-and-plate cooler. Finished in stealthy black for an OEM+ look and backed by the Mishimoto Lifetime Warranty.
