Servicing interval question

[Fencingboy]

Hey, I'm new here and so I apologize if this has been asked before but I can't find it in my workshop manual. What's the service interval on my airbox corn?

If it popped, replace it.

Be careful with that stuff -- the bike's handling could get squirrely if you remove it!
