DESCRIPTION
Lower Charge Air Temperature, Reduce Heat Soak & Stabilize Power Output For BMW G-Chassis B48 / B58 Models.
This upgraded dual-pass high capacity aluminum chargecooler heat exchanger serves as the low-temperature radiator for the factory water-to-air induction system. Enlarged core area and optimized dual-pass fluid circuit greatly improve heat exchange efficiency, effectively suppressing temperature rise during continuous high-load driving and preventing power loss caused by heat soak.
Fully aluminum construction with durable black powder coating. Precision engineered to OEM dimensions for direct bolt-on replacement, matching all original mounting points and pipe connections without cutting or modification.
OE Reference Number: 17118484638
