Dammage new piece of gear

I would run the bike and put a splash of water on the outside of the intake to see if it's pulling in air / anything from that crack. If so, you could probably put some kind of epoxy where the rubber is missing. If it's not pulling in any air through that crack then you'd be good to go (if you're ok with the aesthetics).

Thanks for your advice. I finally put a bit of black silicon and I think it's all set. Run like a charm.
