Used OEM turbo intercooler, Audi part number 1K0145803S. This intercooler also replaces 1K0145803A, 1K0145803AP, 1K0145803, 1K0145805A, 1K0145805, and 1K0145805D. It's the charge-air cooler that sits between the turbo and intake manifold, cooling compressed air before it enters the engine. A failing intercooler can cause a boost leak, resulting in reduced power, poor throttle response, or visible oil seepage at the connections. This unit fits 2.0L turbocharged and naturally aspirated four-cylinder engines across Audi and Volkswagen models.
