Our 2004 Indy 500 (S04NB4Bs) air box was home to a mouse. He's been evicted but left a mess that reached all the way to the carbs. We can clean the carbs but not sure what to do about replacing the contents of the air box. With some patience got the box open and whatever was in there in terms of foam was all chewed up and defiled. I can't find part numbers listed for the foam. Any suggestions on what we can do? Thanks!
