What's the purpose? I have remaines on both side of some panels m redoing.

I don't really know, Matt. I just figured they helped keep the lower rear of the covers from rattling? I hope someone can give you a better answer. I don't use them except in the winter.

It is to help stop the re-circulation of hot engine air into the engine. very important! Deere improved the firewall and insulation design on the 316/318/420 series.

I replaced the foam on the side panels of my 317s that have the original KT17 engines.

I just added multiple layers of the firewall insulation I sell to make up a block same size as original.

Ah good point! I will be sure to add them.

My side panels have no remains of the original foam. Does anyone have the dimensions of the foam block and a picture of where it goes on the side panels?
