At my last oil change, I noticed that the airbox on my 0-320 carburated engine had minor chafing at the lower left where it is rubbing against the cowling. It will probably worsen as the engine sags. My plane is painted, so I don't want to modify the cowl. If I slightly modify the airbox, what material is used? I vaguely remember that it's not fibergalss, so I think that a different resin and material is needed if I modify it. Is a slight airbox mod acceptable and what problems, if any could it cause? thanks
