I wondered why they put a heat keeper cover on engines nowadays, our work vehicle, Ford Explorer has one too. I removed mine to cote the bottom side with stainless or copper foil as an RF shield and ground it, because i'm getting bad spark plug noise on my CB radio. In the old days I would just change the plug wires and add suppressors to reduce it. I installed ground straps on both sides of my hood but no change was noticed. Has anyone seen a stamped stainless cover for sale anywhere?
