do88 Front Intercooler Radiator — BMW F8X M2C/M3/M4

Part of a two-radiator system that cools the S55's water-to-air intercooler circuit. This is the larger of the pair, mounted in the front of the center cooling module.

⚠ Works as a Pair

The S55's intercooler coolant circuit uses two parallel radiators — this front unit and a separate side-mounted radiator. do88's tested temperature figures reflect both installed together. Fitting this alone will still help, but the full benefit assumes both radiators are upgraded.
