What you could also do is cut a whole in your body to allow more air to flow round it but this depends on wether your willing to ruin the body a bit. If you are thinking about doing this ou could find places on the body where it could make it look better, for instance a place which looks like an air vent could be cut out and turned into a real air vent and I would also put some chicken wire in the gap to prevent rocks and dirt to get in.
