The OE Match Performance Chip has been developed precisely for this purpose, delivering sharper performance without compromising reliability or drivability.
1987 Model Year – 24-Pin or 28-Pin?
1987 was a transition year, with Porsche changing from a 24-pin EPROM to a 28-pin version during production.
The only reliable way to determine which chip your vehicle requires is to remove the DME control unit and count the number of pins on the original EPROM. The factory chip is a black rectangular unit fitted with a silver foil label displaying a number similar to 1267355xxx.
If your DME contains a 24-pin EPROM, this is the correct OE Match Performance Chip. If your vehicle has a 28-pin chip, please select the dedicated OE Match 28-pin version.
Developed to Transform the 3.2 Carrera
This is far more than a generic replacement EPROM. Every OE Match Performance Chip has been written from the ground up following hundreds of hours of software development, road testing and dyno evaluation across more than one hundred Porsche 3.2 Carrera models.
Exclusive OE Match programming delivers:

A deteriorated seal can allow moisture and dirt to enter the indicator housing, potentially leading to corrosion, electrical issues, and damage to the surrounding paintwork. Replacing a worn seal restores the correct fit and weather protection, making this OE Match component ideal for routine maintenance, lighting repairs, and Porsche restoration projects.
What This Product Does:
- Forms a weather-resistant seal between the indicator housing and bodywork.
- Helps prevent water and dirt from entering the indicator assembly.
- Reduces vibration between the lamp housing and vehicle body.
- Protects surrounding paintwork from wear and moisture.
- Restores the correct fit of the turn signal indicator.
- Replaces hardened, cracked, or deteriorated original seals.
- Provides an OE-style fit and dependable quality.
Symptoms Of Wear Or Failure:
- Cracked, hardened, or perished rubber seal.
- Water or condensation inside the indicator lens.
- Dirt or moisture around the indicator housing.
- Loose-fitting indicator assembly.
- Corrosion around the lamp mounting area.
- Damage to the surrounding paintwork caused by seal deterioration.
- Lighting restoration requiring replacement sealing components.
Why Replacement Matters:
- The turn signal indicator rubber seal is a small but essential component that protects the indicator assembly from water, dirt, and vibration while ensuring a secure fit against the bodywork. A deteriorated seal can allow moisture to enter the lamp housing, leading to corrosion, electrical faults, reduced lighting reliability, and potential damage to the surrounding bodywork.
- Replacing the rubber seal restores effective weather protection, improves the fit of the indicator assembly, and helps preserve both the lighting system and the vehicle's exterior finish. Manufactured as a direct replacement and produced to OE-style specifications, this OE Match turn signal indicator rubber seal provides the correct fit, dependable quality, and long-lasting durability, making it an excellent choice for Porsche maintenance, repairs, and restoration projects.
