A-Premium Auxiliary Radiator - Cooling for BMW F30 — Overview

This is an auxiliary cooling radiator for F30-based cars that use a side-mounted extra radiator as part of the factory cooling setup. On these BMWs, the aux radiator helps manage coolant temps when the main radiator alone is not enough, especially in traffic, hot weather, or on tuned cars that see more load. If your original unit is leaking, bent up, or corroded at the end tanks, this is the straightforward replacement.

I’d pick this over used OEM if you just need to get the car back on the road without spending dealer money. It makes sense for stock daily drivers and lightly modified cars where you want proper cooling function, not a big-ticket upgrade. Just make sure your specific F30 configuration actually came with the auxiliary radiator, because not every trim and engine setup uses the same cooling layout.
