This allows for quick and easy installation. The aluminum tubes have an outer diameter of ø 60mm. The intercooler kit is installed in the front between turbocharger and intake manifold. It is suitable for the vehicles listed above. The purpose of an intercooler is to cool down the air heated by the turbocharger. By cooling down the compressed air, more air mass enters the combustion chamber at the same volume and more fuel can be burned, increasing power and efficiency. The lower the charge air, the lower the thermal load on the engine, the turbocharger as it requires less speed for the same air mass. Fuel consumption is also reduced and the engine achieves slightly better emissions values, provided the control unit is adjusted accordingly. It is important to ensure that the intercooler gets as much airflow as possible. The intercooler kit offered here is made entirely of aluminum with cast housings, has 5 mounting points and a Bar'n Plate core. Power up to approx. 450hp is possible. Ideal for motorsport and tuning. Every intercooler is tested up to 5 bar before delivery.
