Has anyone installed the factory firewall insulation piece that didn't have it before in the engine compartment? If so did it seem to make any reduction of interior noise? I know the insulation on the firewall on the interior is very thick, so I have my doubts if the piece in the engine compartment makes a difference but don't have any personal experience.
