I was looking to fix a valve cover leak on my wifes SRT6, and I got as far as getting the air box pulled from the engine. Is there a trick to getting the rubber boot off that goes between the air box and the y pipe? It's factory clamped on on the air box side, and where it slips over the y pipe it almost appears to be glued. It might just be old, but I don't want to be buying a new one either.
