When I finish modifying the step in my '73 Sequoia, I will have some 3/4" plywood just a couple inches from the the exhaust pipe coming off the driver's side manifold.
I plan to put a sheet metal heat shield there to keep it from burning.
It seems to me that heat shields work by having a gap where air can flow so the shield can dissipate the heat. So the shield should have some space between it and the part being protected, right?
Does a heat shield work almost as well if attached to the part being protected without an air gap?
