Engine bay sound proofing damping mat. Porsche 911 1965-89 91155689101

Engine bay sound proofing damping mat.
This pad is installed in the engine bay to dampen noise, reduce heat transfer, and help maintain a quieter cabin. It’s made to match the original shape for a direct fit, offering effective sound insulation and thermal protection.  

Fits:
Porsche 911 / 912 1965 - 1989

Diagram ref no 26

Location: In the engine bay, frequently mounted on the firewall or underside of the engine cover, replacing old or deteriorated insulation material

What this product does:
• Acts as a sound-dampening layer in the engine compartment
• Reduces engine noise entering the cabin
• Helps buffer heat, protecting nearby components and minimizing radiant heat transfer

With age, engine sound insulation pads can sag, crack, or break down, reducing their effectiveness at blocking noise and controlling heat. When this happens, more engine noise enters the cabin and heat may affect nearby components. Replacing the pad restores quiet cabin comfort and proper thermal protection in the engine bay.
