MISHIMOTO BMW F80 M3/M4 Performance Oil Line Kit 2015-2020

The Mishimoto Oil Cooler Line Kit adds flexibility and improved durability to the S55 oil‑cooling system in the 2015–2020 BMW F8X M3, M4, and M2 Competition. From the factory, these vehicles use rigid hardlines routed between the oil cooler and oil pump. Over time, these lines are prone to abrasion and corrosion, which can lead to leaks and compromised lubrication.

Mishimoto replaces the factory hardlines with application‑specific nylon‑braided hoses equipped with ‑10AN fittings, providing a secure and resilient oil channel capable of withstanding the demanding conditions under the hood of an F8X. The kit includes all necessary hardware to adapt the new lines to the S55 platform. Blue‑anodized aluminum adapters convert the oil‑pump housing for ‑10AN use, while a second set of adapters ensures proper fitment to either the OEM oil cooler or the Mishimoto bar‑and‑plate cooler.

The nylon‑braided lines are finished in a stealth black to maintain an OEM+ appearance. As with all Mishimoto components, the Oil Cooler Line Kit is backed by the Mishimoto Lifetime Warranty for long‑term confidence and reliability.
