VCTR Performance BMW M2/M3/M4 F8X S55 Auxiliary Radiators

Overview

The factory S55 radiator manages coolant temperatures within OEM parameters, but for track or sustained hard driving, the stock unit's capacity becomes a limiting factor. This aluminium radiator provides improved heat dissipation in a direct-fit package.

Why Upgrade?

• Improved coolant heat dissipation over the OEM radiator
• Better resistance to coolant temperature rise during hard driving
• Direct replacement for the factory radiator
• Aluminium construction for improved heat exchange

Built for the Drive, Not Just the Dyno

Coolant temperature is the ceiling everything else on the S55 has to live under — more boost, more heat, and the factory radiator was never sized with a track day in mind. Upgrading it isn't the upgrade you show off, but it's the one that lets every other upgrade keep working when it matters most.
