BMW Radiators for BMW 3 Series G20 (2019+)

Clear BMW chassis

We sell only OE supplier or approved aftermarket upgrade radiators for your BMW. It seems BMW took some shortcuts when it came to radiator design and used weak materials like plastic for critical connection points. If you are tracking older models like E30, E36, or E46, you probably are well aware of these issues. As these cars age, the plastic pieces become more brittle and failure prone. The solution is to replace with upgraded radiators that perform as upgrades for the original, failure prone radiator to avoid being left on the side of the road or, worse yet, the track.

The benefits are most noticed during back to back runs at higher boost levels where the factory cooling capacity can be overwhelmed resulting in ignition timing pull and reduced turbo efficiency.
