FIREWALL CUSTOM INSULATION KIT POLYMER BLACK BACKING SILVER

MIA's Description

The HushMat 742302 is a custom vehicle firewall sound deadening and thermal insulation kit designed for the 2016-2021 Tesla Model X. This USA-made material helps reduce engine noise, exhaust drone, road noise, and vibrations. It also minimizes heat transfer from the engine, headers, and exhaust system, creating a more comfortable interior environment and reducing the workload on your HVAC system.
HushMat Ultra is a lightweight, flexible, and easy-to-install material that adheres directly to the firewall, covering 100% of the area from the instrument panel to behind the pedals. It is water and weather resistant and tested to be self-extinguishing.
