The Dinan 17-20 BMW 430i Heat Performance Exchanger is a high-performance cooling component designed to enhance thermal management for the F2x/F3x chassis. Featuring a robust 48mm thick core—significantly thicker than the OEM 27mm core—this heat exchanger provides 78% more heat transfer surface area, resulting in superior cooling capacity. Its unique "L" shaped end tanks contribute to increased thermal mass, allowing the exchanger to absorb, store, and release heat more effectively than stock units. This upgrade helps mitigate heat-related issues during demanding driving conditions, ensuring consistent engine performance and extended maximum performance time.
Designed specifically for 2017-2020 BMW 430i models, this heat exchanger is a direct bolt-on upgrade for vehicles equipped with the B58 engine. It is suitable for street, track, or spirited driving, offering improved cooling efficiency to support higher performance applications. The kit includes the heat exchanger with its specialized end tanks, ready for installation without modifications. Compatible with the OEM setup, this component enhances thermal management and helps maintain optimal engine temperatures during intense driving sessions.
