Dongfeng Tianlong Flagship Air Intake Hose-intercooler 1119120-H0100 Dongfeng 530

The 1119120-H0100 Intercooler Air Inlet Hose Assembly is a high-performance duct designed to connect the turbocharger outlet to the intercooler inlet in the intake air system of Dongfeng heavy-duty commercial vehicles. As a key component in the engine’s forced induction circuit, it ensures efficient delivery of pressurized, high-temperature air from the turbocharger to the intercooler for cooling before entering the combustion chamber.

Engineered to withstand extreme thermal cycling, pulsating pressure loads, and constant engine vibration, this hose assembly is available in two primary configurations: reinforced silicone rubber or steel pipe with heat shielding, depending on vehicle specification and model year. Used primarily on Dongfeng Kinland KX/GX series and other long-haul 6x4 tractor units equipped with Cummins or Dongfeng Dragon Engine platforms, it plays a vital role in maintaining optimal engine performance, fuel efficiency, and emissions compliance under full-load operation.
