So Ive had my GruppeM intake for close to a year now and I love it. I got my car back from the dealer yesterday for other reasons, and since then, everytime i turn OFF the car, a big swoosh noise comes from under the hood. It's as if one last bit of air is being sucked in or blasted out of the intake, as the car turns off. I wouldnt mind it at all, and my car seems to be driving normally, but this never happened before. Like I said, the intake has been installed for a while now, and just since yesterday has this noise been happening. Should I worry about? or just leave it be?
