Description
Support charge-cooling consistency on 2015-2018 BMW M3 with the Dinan High Performance Heat Exchanger.
The exchanger rejects heat from the liquid cooling circuit that supports the charge-air cooler. Increasing its heat-transfer capacity helps manage repeated high-load operation, where rising coolant temperatures can reduce the system’s ability to cool the intake charge.
