The OE thermal management system for the B4x/B58 G-chassis BMW and Toyota GR Supra offers an improved formula from prior generations. With a setup where engine coolant is also re-routed through the heat exchanger, the system effectively assists in overall engine cooling as well as charge cooling. However, like its predecessors, it has room for improvement as it can be overwhelmed when the system is taxed aggressively or as power levels are increased.
Fits: BMW M340i (G20), BMW M440i (G22), BMW M240i (G42), BMW Z4 M40i (G29), Toyota GR Supra (A90). Confirm fitment with us before ordering.
