Actually, I found out there were holes in it (on the underside of the duct) by accident. So not sure how long its been like this. The hole is about the size of a quarter. I am assuming some air must been making it through.
I did picked up the part at the dealer today and will put it in tomorrow. Hopefully, its not too late. And I do have a aftermarket sub
Should I be worry about it since I don't know how long I've been riding like this?
