1J0 145 834 Q: Lower intercooler hose for Volkswagen Golf 4 TDi 150 hp

This lower intercooler connection hose is intended for the Volkswagen Golf 4 and Bora, including 4Motion versions, equipped with the 1.9 TDi 150 hp engine (engine code ARL). It provides the connection between the intercooler and the inlet circuit, and replacement is necessary when it shows cracks, softening or air leaks that may degrade engine performance. In the context of restoring or servicing a classic vehicle, using a new replacement part ensures proper functioning of the turbocharging circuit. A hose in good condition directly contributes to the reliability and longevity of the powertrain.
