This OE Match engine bay sound proofing damping mat is a direct replacement for the original Porsche insulation panel used in the engine compartment of 964-generation 911 models. Mounted to the underside of the engine lid or engine bay bulkhead depending on application, it helps absorb engine noise and vibration while also providing thermal insulation.
Fits:
Porsche 964 1989 - 1994

This sound proofing mat absorbs engine noise and vibration generated within the engine compartment, reducing sound transmission into the cabin. It also helps insulate against engine heat, improving comfort and maintaining a cleaner engine bay appearance.
Function
• Reduces engine noise and vibration entering the cabin
• Provides thermal insulation within the engine compartment
• Helps maintain factory refinement and driving comfort
• Protects surrounding panels from heat exposure
• Restores original engine bay appearance and insulation performance
Position: Engine compartment / engine lid insulation area
OE reference: 96455628103
Cross references: 96455628100, 96455628101
Typically 1 required per vehicle
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 create an untidy appearance. Replacing the mat restores proper acoustic insulation, improves engine bay presentation, and helps maintain cabin comfort.
When to replace
• Original insulation foam is crumbling or deteriorating
• Increased engine noise inside cabin
• Visible sagging or separation of insulation material
• During engine bay restoration or repainting
• Heat damage or contamination from oil and debris

OEMatch Engine Compartment Seals — Durability, Sealing, Performance
OEMatch engine compartment seals restore and maintain sealing, airflow control and component protection for Porsche models. They are suitable for restoration projects, routine maintenance and engine rebuilds, helping to keep wiring, hoses and bodywork free from moisture, dust and debris.
Understanding OEMatch Engine Compartment Seals
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original engine compartment seals.
OE (Original Equipment) refers to parts matching original specifications for the engine compartment seals and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM engine compartment seals engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models.
Engine compartment seals sit between body panels and the engine bay to control airflow, retain cooling efficiency and exclude contaminants. Typical materials include EPDM and neoprene rubber chosen for heat and weather resistance. Correctly fitted seals reduce heat transfer to adjacent panels, limit ingress of water and grit, and protect electrical connectors, sensors and hoses from premature wear.
Available Types
- Edge seals and weatherstrips for engine bay perimeters
- Cooling bay seals and duct seals to guide airflow
- Rear engine bay perimeter seals and scuttle seals
Benefits Include
- Restores correct cooling airflow and engine bay thermal balance
- Prevents moisture, dust and debris from reaching sensitive components
- Protects wiring, hoses and sensor connections from contamination
Why Engine Compartment Seals Wear and Fail
- Heat exposure causing hardening, cracking or loss of elasticity
- Chemical attack from oil, fuels or cleaning fluids
- Compression fatigue and abrasion from vibration or misalignment
The Importance of Replacing with OEMatch Engine Compartment Seals
OEMatch Engine Compartment Seals components are compatible replacements engineered to original-spec dimensions and tolerances — a practical option when genuine or OEM parts are unavailable. Replacing degraded seals restores airflow control, reduces corrosion risk and prevents overheating or electrical faults that can follow prolonged exposure to moisture and debris.
Advantages
- Designed as direct-fit alternatives to original parts for straightforward installation
- Available in materials selected for heat, oil and weather resistance
- Suitable for classic restorations and modern maintenance tasks
Support & Advice
Fitting can appear straightforward but may require specific procedures such as correct positioning, sealing detail and careful reassembly to avoid panel damage. If you lack the right tools or experience, or if the vehicle includes hidden fasteners or sensors, seek professional installation. Recheck fasteners and seal compression after initial use.
