Dinan High Performance Heat Exchanger - 2019-2025 BMW 330i/M340i/430i/M440i
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. Once overburdened, this results in the undesirable outcome of power being diminished. Avoidance of this unwelcome scenario can be attained though with a Dinan heat exchanger that improves the overall thermal management system so everything runs cooler and more efficiently while being budget friendly.
Features:
- Average of 8.7? C reduction in charge air temps with a maximum reduction of nearly 12? C over 30 successive WOT pulls
- General improvement to the efficiency of the thermal management system, inclusive of engine cooling
- 45mm thick Dinan core vs. 26.75mm thick stock cooler core
- 68% more cooling surface area and volume than stock
- Reduces the tendency to heat soak / go in to limp mode
- Durable bar and plate design that is less susceptible to damage from road debris
- Pressure tested, 100% TIG welded, Aluminum construction
- Direct fit replacement with no modifications required
