Description

The HushMat 625612 is a custom-fit firewall insulation kit designed for the 1961-1964 Pontiac Bonneville. It effectively reduces thermal transfer from the engine, headers, and exhaust into the vehicle's interior, making the cabin cooler in the summer and warmer in the winter. This kit also minimizes road and engine noise, contributing to a more comfortable and less fatiguing driving experience.
