Philosophy/Functionality
The AC Schnitzer intercooler reduces the high temperature of the intake air caused by turbocharging, thus ensuring better filling of the combustion chamber. Since cooler air contains more oxygen than warm air for the same volume, the AC Schnitzer high-performance intercooler supplies more oxygen to the combustion chamber. This leads to more stable engine performance and higher torque. With an 85% larger airflow area and over 90% more charge air volume, the AC Schnitzer high-performance intercooler offers noticeable advantages over the standard intercooler thanks to its size and stepped design. The Performance high-performance core achieves outstanding cooling properties. This innovative development guarantees sustained and homogeneous power delivery from the engine. Even at high outside temperatures, engine performance remains noticeably more stable. In addition, the lower temperatures during the combustion process provide further advantages: the engine has a lower tendency to knock, and the thermal load on the pistons is reduced. This increases the service life of the engine.

Material/Assembly
The end boxes of the AC Schnitzer high-performance intercooler are made of cast aluminum. Using flow analysis, they were then further optimized in CAD-based simulations. Design: stepped, performance high-performance core. Material: cast aluminum. Processing: CAD-based simulations and optimizations. Installation is achieved by replacing the standard intercooler and is therefore easy to perform, as the original charge air hoses can still be used.
