Mishimoto Charge Air Cooler — F8X M3/M4

Upgrade your 2015–2020 BMW F80 M3, F82 M4, or F87 M2 Competition with the Mishimoto Performance Air-to-Water Intercooler, engineered to improve charge-air cooling, airflow, and performance on the S55 engine. Featuring a larger bar-and-plate core with TIG-welded cast aluminum end tanks, this intercooler increases core volume by 29% while maintaining a direct-fit installation with no modifications required. Internal air diverters promote even airflow through the core, while the single-pass coolant fin layout maximizes heat transfer from charged air to coolant.

Testing showed a 16% increase in intercooler flow and a 12°F reduction in intake air temperatures when paired with the Mishimoto Performance Heat Exchanger. Dyno testing also recorded average gains of 11 whp and 8 wtq, with peak gains reaching up to 31 whp and 10 wtq. Built for increased boost and long-term durability, this S55 intercooler is backed by the Mishimoto Lifetime Warranty.
