Description

The Hushmat 617482 Custom Vehicle Firewall Sound Deadening and Thermal Insulation Kit is designed to cover 100 percent of your vehicle's firewall, from behind the instrument panel to the pedals. This kit helps reduce thermal transfer into the interior, making the cabin cooler in summer and warmer in winter, and also lessens road noise and exhaust drone.

Made from HushMat Ultra material, it uses a proprietary USA manufactured chemistry to dissipate heat and insulate the interior, improving the efficiency of your HVAC system.
