OE Match
OE Match for Porsche
OE Match is a specialist replacement-parts brand developed around Porsche applications, covering routine maintenance, mechanical repairs, restoration and difficult-to-source components for classic and modern models. Design911 selects brands for quality and Porsche fitment, with knowledgeable specialists available to help owners and workshops choose suitable parts.
The OE Match story
OE Match is focused on preserving Porsche vehicles by returning hard-to-find and no-longer-available components to the market. Its purpose is to keep Porsche vehicles maintained, repaired, restored and usable for the future, particularly where original components have become expensive, difficult to source or discontinued.
Supplied catalogue information records over 8000 individual part numbers, more than 11,800 OE cross-references and over 100 new products in engineering, while the wider product programme contains more than 9,000 variants; these figures describe different measures of the range. Continuing development involves researching the parts owners and workshops genuinely need, working with specialist manufacturers, reviewing engineering specifications, assessing samples, testing and approving components before release. From small seals, clips and brackets to major mechanical components, the aim is to prevent a difficult-to-source item from holding up an entire repair or restoration: preserving Porsche, one part at a time.
Why choose OE Match for your Porsche
OE Match is a quality aftermarket and OE-equivalent replacement option developed specifically around Porsche applications rather than adapted from a general aftermarket range. Original references, vehicle fitment information, dimensions, materials and component specifications are used to identify suitable replacements for routine service, age-related wear, larger mechanical repairs and restoration work.
Its research, development and quality-control processes assess material and manufacturing quality, dimensions and specification, OE-reference compatibility, vehicle application, fit and function, supplier samples, product consistency, packaging and presentation. Where appropriate, physical inspection and fitment evaluation form part of final approval, and products must meet the programme's requirements before entering the catalogue.
Coverage includes the Porsche 356, 911, 912, 914, 924, 944 and 928, alongside the 964, 993, Boxster 986, 996, Cayenne, Cayman and 997. This gives owners, enthusiasts, independent specialists and professional workshops a Porsche-focused replacement option alongside Genuine Porsche parts. OE Match is intended to provide correctly specified, OE-equivalent replacements with sensible running costs rather than simply serving as a lower-cost alternative. Design911 selects the brands it carries for quality and fitment and can advise customers on suitable options for maintenance, restoration or upgrades.

OE Match 28-Pin Performance Upgrade Chip – USA/Canada Specification SSI or Performance Headers
Unleash the full performance potential of your 1987-1989 USA/Canada specification Porsche 911 Carrera 3.2 with the OE Match 28-Pin Performance Upgrade Chip, engineered specifically for 930/21 and 930/25 catalyst engines fitted with SSI heat exchangers or performance headers, while retaining either the factory rear silencer or a sports muffler.
Fits:
- Porsche 911 1987-1989 3.2L G50
SSI heat exchangers and performance headers dramatically improve exhaust scavenging and engine breathing, allowing the legendary 3.2-litre flat-six to produce more usable power throughout the rev range. To fully exploit these modifications, the Bosch Motronic ECU requires a calibration specifically written for the increased exhaust flow. 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:
- Smoother idle with virtually no idle hunting
- Increased low and mid-range torque
- Sharper throttle response
- Elimination of the factory flat spot below 4,000 rpm
- Reduced RPM dipping during deceleration
- Reduced overrun backfiring
- Stronger pulling power from just 1,500 rpm
- Dyno-proven horsepower and torque gains throughout the rev range
The result is a Carrera that feels lighter, more responsive and considerably quicker in everyday driving. Many owners describe the improvement as making the car feel as though it has lost 500-600 pounds, with stronger acceleration and improved flexibility in every gear.
Many customers also report 10-15% improvements in highway fuel economy, thanks to the refined part-throttle fuel and ignition mapping.

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.

OE Match Performance Upgrade Chip – USA/Canada Specification Pre-muffler / Cat Bypass Configuration
Unlock the full potential of your 1984-1986 USA/Canada specification Porsche 911 3.2 Carrera with the OE Match Performance Upgrade Chip, developed specifically for 930/21 and 930/25 catalyst engines fitted with a pre-muffler or catalytic converter bypass pipe, together with either the factory rear silencer or a sports muffler.
Fits:
- Porsche 911 1984-1986 3.2L
Replacing the restrictive catalytic converter allows the engine to breathe more freely, but without optimised Bosch Motronic calibration the full performance benefits cannot be realised. This OE Match chip has been specifically engineered to complement a premuffler or cat bypass exhaust, optimising ignition timing and fuel delivery to maximise both performance and drivability.
Planning to install a premuffler or cat bypass later? No problem. This chip can be installed now and used with the standard catalytic converter before upgrading the exhaust at a later date, allowing you to enjoy immediate improvements while remaining fully compatible with your planned modifications.
Designed for Maximum Drivability
Developed through hundreds of hours of coding, road testing and dyno development on more than one hundred Carrera 3.2 models, this is far more than a generic replacement EPROM.
Exclusive OE Match software delivers:
- Smoother idle with virtually no idle hunting
- Increased low and mid-range torque
- Sharper throttle response
- Elimination of the factory flat spot below 4,000 rpm
- Reduced deceleration backfiring and RPM dipping
- Strong pulling power from as little as 1,500 rpm
- Dyno-proven horsepower and torque gains throughout the rev range
The transformation is immediate, making the car feel lighter, more responsive and significantly more enjoyable to drive. Many owners describe the improvement as feeling like the car has lost 500-600 pounds in weight.
Many customers also report 10-15% improvements in highway fuel economy, thanks to more efficient part-throttle mapping.
Engineered Specifically for Premuffler & Cat Bypass Cars
Unlike generic performance chips, this calibration has been developed specifically for Carrera 3.2 models equipped with a premuffler or catalytic converter bypass. By matching the engine management to the improved exhaust flow, the Bosch Motronic system can fully exploit the benefits of the freer-flowing exhaust while maintaining excellent reliability and everyday usability.
