CSF Front Mount Heat Exchanger — BMW M3/M4 (F8X)

Upgraded front-mount heat exchanger for the S55-powered F80 M3 and F82 M4, feeding the water-to-air charge cooling circuit. Includes a rock guard to protect the core from road debris.

Lowering coolant temperature in this circuit directly lowers intake air temperature — the single biggest factor in holding power through repeated hard laps.
