BMW F8X S55 Top-Mount Chargecooler Upgrade by Mishimoto | Part No. MMINT-F80-15

Transform your S55-powered BMW with Mishimoto’s coolant-to-air top-mount chargecooler. This A2W core is a straight swap for the factory unit on M2 Competition, M3 and M4, delivering colder intake temps, improved airflow and dependable power you can feel lap after lap. Whether you enjoy fast road driving, track days or have a tuned 3.0 twin-turbo build, this is the cooling upgrade that keeps heat soak in check and performance consistent.

We run this unit on our own in-house S55 and customer cars, and the feedback is the same every time: quicker recovery, stronger mid-range punch and repeatable results on back-to-back pulls. It looks OEM plus in the bay and works brilliantly with stock mapping or remapped setups.
