HI, just fitted the GruppeM on my car, it sounds amazing and more powerful. But there are some noise (or say sound)from the airbox when the car parked on the road.
Is this normal sound from GruppeM? Just want to make it is in normal condition. Becuase with OEM airbox, there are totally no sounds comes from there. Thank you~
