very easy and Cheap too haha
just need to go to a $2 shop and find the Thick Foil sheeting for stove top wall around $2-$10 up to the area you in. and lay it out so it blocks air from the engine side and let air in from under the light. Make one big U shape for the bottom and another for the top.(This is just a Cheap Ass way) One thing good about the Foil is it don’t heat up and if you are Very keen about the heat just Double up the sheeting!
