You can get the parts from a dealer or Phil should be able to find them for you. There are actually two pieces, the band and the lock, best to replace both, since it's very easy for false air to enter the system at that joint. I would look up the PNs but the EPC is down at the moment. I will try again later.

You did check the air guide very carefully for cracks?
