Information
Engine bay insulation mat
This OE match engine bay insulation mat is a direct replacement for the original Porsche soundproofing panel fitted to 993-generation 911 models. Installed on the underside of the engine lid or within the engine compartment, it helps absorb engine noise, damp vibration, and provide thermal insulation from the air-cooled engine.
Fits:
Porsche 993 1995 - 1998
Diagram ref no 13
These insulating mats are produced to the highest quality standards and hardly distinguishable from the original, partly no longer available insulating mats.
This insulation mat absorbs engine noise and vibration generated within the engine compartment, helping reduce sound transmission into the cabin. It also provides thermal insulation, reducing radiant heat transfer and improving driving comfort.
Advantages:
• Self-adhesive back
• Temperature resistant from -40 ° C to + 150 ° C
• Meets the automotive standards for fire behavior according to FMVSS302, DIN 75200
• Precise design (structure, thickness and shape) according to the original insulation mats
• True to original material
• noticeably less noise and radiant heat from the engine compartment
Original engine bay insulation mats commonly deteriorate over time due to heat, oil vapour, and age. As the foam breaks down, it can crumble into the engine bay, reduce sound insulation effectiveness, and negatively affect engine bay appearance. Replacing the insulation mat restores acoustic performance, improves thermal protection, and refreshes the engine compartment.
When to replace
• Original insulation foam is crumbling or deteriorating
• Increased engine noise inside cabin
• Visible sagging or peeling insulation
• During engine bay restoration or repainting
• Heat or oil contamination damage

Information
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.

The OE Match Engine Bay Sound Proofing Damping Mat is a premium-quality replacement insulation panel designed to reduce engine noise and restore the original appearance of the engine compartment on compatible Porsche models. Manufactured to OE specifications for fit, thickness and durability, this sound proofing mat helps absorb engine noise and vibration while providing a factory-style finish to the engine bay.
Fits:
- Porsche 911 1975-1977 3.0L Turbo (930)
- Porsche 911 1978-1989 3.3L Turbo (930)
Manufactured from high-quality heat-resistant acoustic insulation material, the damping mat is engineered to withstand elevated engine bay temperatures, moisture, oil vapours and continual thermal cycling. Precision-cut to match the original contours and mounting locations, it provides direct OE-style fitment and is ideal for replacing deteriorated, oil-soaked or damaged original insulation during restoration, refurbishment or routine maintenance.
What This Product Does:
- Reduces engine noise transmitted into the cabin.
- Dampens engine vibration and sound resonance.
- Restores the original appearance of the engine bay.
- Provides thermal and acoustic insulation.
- Helps protect surrounding panels from engine heat.
- Improves overall cabin comfort and refinement.
- Provides factory-style fitment and finish.
- Forms an essential part of the engine compartment insulation system.
Symptoms Of Wear Or Failure:
- Increased engine noise inside the cabin.
- Sagging or detached insulation.
- Cracked, brittle or deteriorated insulation material.
- Oil contamination or staining.
- Heat damage or discolouration.
- Missing sections of insulation.
- Loose material within the engine bay.
- Poor engine compartment appearance.
- Reduced sound insulation effectiveness.
- Age-related deterioration due to heat and moisture exposure.
Why Replacement Matters:
- The engine bay sound proofing mat is continually exposed to high temperatures, engine vibration, moisture and oil vapours. Over time, the insulation material can harden, crumble, become oil-soaked or separate from its backing, significantly reducing its ability to absorb engine noise and withstand engine bay conditions.
- A deteriorated sound proofing mat can increase engine noise within the cabin, reduce driving refinement and detract from the appearance of the engine compartment. Loose or damaged insulation may also interfere with surrounding components if left unattended.
- Replacing a worn or damaged sound proofing mat restores the original acoustic insulation and factory appearance of the engine bay. The OE Match Engine Bay Sound Proofing Damping Mat is manufactured to OE standards using premium heat-resistant materials, providing precise fitment, excellent noise reduction and long-lasting durability, making it the ideal choice for Porsche restoration, servicing and preventative maintenance.
