i recieved my copper iso thermal spacer and had 2 quick questions...it came with a gasket for the lower manifold, do i have to install that as well? it also came with a throtle body spacer, is that necessary to install? b/c i have not seen anyone on here with it installed.
I live in CT but i do not drive the car in the winter, i just start it up every now and then to keep it running.
thanx ahead of time
