If you install a strut tower brace, the brace will keep the insulation from rubbing on the plenum cover. I would go with a single bar strut tower brace so the brace does not interfere too much with the visual you get from the plenum cover. I have a double bar tower brace and it kinda takes away from the graphics. Steeda makes a nice single bar for around 99 bucks. IMO. Good luck!
