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.

OEMatch Sound Proofing — Fit, Function, Confidence
OEMatch Sound Proofing for Porsche models offers materials and kits selected to reduce cabin noise and improve thermal comfort while supporting restoration and upgrade projects. Products cover floor areas, doors, roof panels and engine bay linings to help retain the characteristic Porsche interior environment.
Available Types
- Interior floor and carpet insulation mats
- Engine bay and bulkhead thermal barriers
- Door, roof and panel lining foams and barrier sheets
- Adhesive-backed damping sheets for vibration control
- Classic restoration kits for period-correct installations
Understanding OEMatch Sound Proofing
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original sound proofing. OE (Original Equipment) refers to parts matching original specifications for the sound proofing and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM sound proofing engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models.
OEMatch provides a wide selection of sound proofing solutions tailored for Porsche applications, drawing on a parts catalogue that includes over 4,000 individual part numbers and more than 8,700 OE cross-references. Over 100 new products are in development. Typical materials include dense damping sheets, closed-cell foams, adhesive-backed mats and heat-resistant liners chosen for specific locations such as floors, bulkheads, doors and engine bays.
Benefits Include
- Reduced road, tyre and engine noise for a quieter cabin
- Improved thermal insulation to lower heat transfer into the interior
- Vibration damping that protects trim and reduces rattles
- Materials and kits suitable for authentic restoration on classic Porsche models
Why Sound Proofing Wear and Fail
- Ageing of damping foams and adhesive breakdown from heat and moisture
- Mechanical abrasion from installed carpet, fittings or repeated access
- Chemical degradation where inappropriate cleaners or fuels have contacted materials
- Poor previous repairs or incorrect adhesives that allow materials to delaminate
The Importance of Replacing with OEMatch Sound Proofing
Replacing degraded insulation maintains acoustic comfort and helps preserve interior trim and wiring from heat and moisture exposure. Correct materials and installation support accurate audio performance and reduce long-term corrosion risk by controlling condensation pathways. For restoration work, using parts selected for Porsche applications assists in achieving faithful results.
Advantages
- Direct-fit replacements engineered to match original dimensions and tolerances
- Material choices selected for specific locations and temperature exposure
- Coverage suitable for both modern and classic Porsche models to simplify project planning
Support & Advice
These items affect systems that contribute to vehicle comfort and protection. Installation should be carried out by a qualified technician following model-specific procedures. If fitting at home, protect trim and use the correct adhesives and fixing methods; when in doubt, seek professional assistance to ensure secure attachment and finish.
