Description

The Hushmat 662712 is a firewall insulation kit designed to reduce heat and noise transfer into your vehicle's interior. Engine, header, manifold, and exhaust heat can create an uncomfortable ride, especially in warmer months, and force your AC system to work harder. This insulation kit helps dissipate heat, keeping your cabin cooler in the summer and warmer in the winter.
