BMW 430i High Performance Heat Exchanger - Dinan - 2019-2026. This direct-fit upgrade improves charge and engine cooling for more consistent performance during spirited driving or when power is increased.

Built around a 45mm Dinan core (vs. 26.75mm OEM), it delivers 68% more heat-transfer surface area and greater thermal mass via full-size end tanks. Testing showed an average 8.7°C drop in charge temps, with peaks near 12°C over 30 successive WOT pulls. The durable bar-and-plate, 100% TIG-welded aluminum unit is pressure tested and helps curb heat soak and limp mode, while remaining budget friendly.
