Mishimoto Performance Heat Exchanger, Automatic – BMW S58 M2 / M3 / M4 (G87 / G80 / G82 / G83)

OVERVIEW

The S58 uses an air-to-water intercooler, and the front-mounted heat exchanger is what pulls the heat back out of that coolant loop. When it saturates on track or on a hot day, intake temperatures climb and the DME pulls timing. Mishimoto's performance heat exchanger adds 23% more core volume and 44% more external fin area in a dual-pass, all-aluminum design.

This is the automatic-transmission version, for cars with the ZF 8-speed.
