Genuine OEM Audi Intercooler, part number 4G0145805N. This heat exchanger is crucial for turbocharged engines, cooling the hot, compressed air from the turbocharger before it enters the engine's intake manifold. By reducing air temperature, it increases air density, leading to greater power output and efficiency. It is positioned within the engine's intake system, often at the front of the vehicle. Weighing 5.706 kg, this intercooler measures 1.06 meters in length. Using a genuine OEM intercooler ensures optimal cooling efficiency, precise fitment, and maintains engine performance as designed.
