Description
Support charge-cooling consistency on 2021-2026 BMW 430i 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.
