The G-Chassis thermal management system improves on prior generations by routing engine coolant through the heat exchanger as well as the intercooler circuit, providing dual-circuit cooling. Even with that improvement, the stock setup can be overwhelmed under sustained aggressive driving or with increased power levels, resulting in reduced performance as charge temperatures climb. The Dinan Heat Exchanger for the BMW G22 430i uses a durable bar-and-plate core to expand total thermal management capacity, producing an average 8.7°C reduction in charge air temperatures with a maximum reduction of nearly 12°C over 30 successive wide-open-throttle pulls, while also contributing to overall engine cooling efficiency.
Features:
+ Bar-and-plate core construction for durable, high-capacity heat transfer
+ Average 8.7°C reduction in charge air temps under sustained hard driving
+ Maximum 12°C reduction over 30 successive WOT pulls
+ Improves both charge cooling and overall engine thermal management efficiency
+ Addresses heat soak that limits the factory system under aggressive use or added power
+ Fits BMW G22 430i with B46 engine
