jeepsr4ever wroteTheir is a heat sheilding amterial you can put on either side of the wall. I have roached my feet many a times on my floorboards from fednerwell exhaust. In the winter it keeps the floors warm, in the summer its hard to wear boots :oops: Untill I went to a heat reducing material I didnt know what a difference it could make. Check out summitracing.com or jegs.com for heat sheild material
Well, I made a plate to cover that 4 inch square hole in the passengers firewall. I took it for a spin last night and what a difference just that made. No it doesn't seem like the heater is on. I don't know why the guy didn't plug it before. At any rate between that and the shielding I ordered I should be in good shape. Heat down here in FL is unbearable during mid day.
