This intercooler hose connects the turbocharger outlet to the charge-air cooler on the left side of the engine. It carries pressurized, heated air from the turbo to the cooler, where the air is cooled before entering the intake manifold. A leak or rupture in this hose causes a loss of boost pressure, resulting in reduced engine power and increased exhaust temperature. The hose is constructed to the original geometry and wall thickness, which maintains the correct air volume and pressure drop across the charge-air system. When replacing, ensure the hose clamps are positioned over the full-width reinforcement bands and are torqued to specification to prevent air leaks.
