I am doing an upper plenum pull and would like to hide the butt ugly coil pack harness. Has anybody ever routed this harness under the upper plenum? I realize this would cause spark plug changes to be much harder, but I think it would be worth it. Besides you don't change plugs that much. Any other problems associated with this? I've done all the deletes and smoothed and painted the upper plenum and want a super clean look.
