Product Description

The Wagner Tuning Side Mount Radiator for the BMW F80 M3, F82 M4 and F83 M4 Convertible is a high-efficiency cooling upgrade designed to support the demanding thermal requirements of the S55 engine.

Mounted in the factory side radiator location, this uprated Wagner unit improves coolant stability during hard driving, helping reduce temperature spikes and maintain more consistent engine performance under sustained load.

Featuring a high-efficiency aluminium cooling core, increased thermal capacity and a CAD-optimised fin structure, the Wagner side radiator is designed to improve heat dissipation for tuned, hybrid-turbo, fast-road and track-driven S55 builds.

With TIG-welded construction and direct OEM-fit installation, this radiator is a strong supporting upgrade for F8X M3 and M4 owners looking to strengthen one of the S55’s key cooling pathways.
