Important Note
The item will be folded for packaging, so there may be creases on the surface upon arrival. These will naturally flatten out after installation. Please keep this in mind before ordering.
Why Upgrade Your Hood Insulation?
The factory hood liner degrades over time, losing its ability to dampen sound and insulate against heat. Replacing it restores your cabin's acoustic comfort and helps protect your engine bay from moisture and thermal stress.
