I need opinions. Im installing an O-200 and the firewall forword kit came with a nice new heat box. However there was no mention of what to use to feed the heat box with air(filter assembly). Where to mount a filter etc with a scat tube? I cant even find a filter assy that isnt a heat box from aircraft spruce. Im thinking of just using the old heat box off the engine.
I would not run it without an air filter of some sort. Will the old box mate with what ever you are using for a carburetor? That would also give you carb heat. which is a must with an O-200. Can you fabricate an adapter for a Brackett filter that would attach to the airbox in the picture?
