After reviewing previous threads re: "my intake air tube has holes, do I need to by the OEM replacement or can I buy the cheap ebay replacement," which concluded "you need to buy the OEM," I decided to try FiberFix repair tape. Not even the automotive version, which is supposedly more temperature resistant. Should you do this? Probably not. But it's held up since August.
Hope this helps somebody else.
