I am trying to bolt something to the side of the coil bracket, and noticed how close it is to the exhaust.
2000 durango.

Just wondering if that is an issue for the coil itself? Does it get too hot? Is there a heat shield?

If I bolt a piece of aluminum to the bolts that hold the coil onto the bracket, to sheild it, will it make it worse or better?

That is will the aluminum suck up more heat and carry it to the coil bracket?
