• Four-stage resonance intake system
• Resonance flaps controlled by vacuum cells (2x)
The resonance flaps open and close depending on the speed of the engine and
thereby have a positive influence on the airflow within the intake system, thus
contributing to a power/torque increase. For functional testing, the vacuum cells (1)
and (2) can be tested using the RaceCon software during vehicle standstill and
activated separately by the computer.
The buttons to be used are Check Reso1 & Check Reso2.
