Cusco Air Inlet Tube - Issue
 

Hey all--

My new Cusco air inlet tube arrived today. Haven't installed yet because I'm a little concerned about the inside of the tube itself. It looks like it's dirty (i.e. rubbing a finger inside brings out black/grey dirt), which I assume isn't awesome since it's behind the filter. Just clean it out with water or something along those lines? Any advice is greatly appreciated, and if this is a stupid question, apologies in advance.

Thanks!

if its dirty, just clean it out with a towel and some all purpose cleaner,, should be good to go after that
