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.

This is an electric air pump that forms the heart of the Porsche secondary air injection (SAI) system. In OE Match form, it’s manufactured to replicate the OE housing shape, mounting points, and electrical characteristics so it installs as a direct replacement when the original pump becomes noisy, weak, or fails.
On cold start, the pump pushes fresh air into the exhaust stream (via the SAI system valves and pipework). This helps the catalytic converters warm up faster and reduces cold-start emissions - supporting smooth compliance with the vehicle’s emissions strategy.
A failing secondary air pump can trigger emissions warnings and drivability annoyances (MIL/check engine light) because the ECU may detect insufficient secondary air flow during cold start. Replacing the pump restores proper SAI operation and helps keep emissions functions working as intended.
When to replace:
• Check engine light / emissions-related fault codes linked to secondary air flow
• Pump runs loudly, squeals, or sounds rough on cold start
• Pump not running during cold start when commanded
• Water ingress/corrosion damage or seized pump motor
• Preventative replacement during secondary air system service

Flywheel Ring Gear – Hardened Steel (OEM 964.114.143.31). This precision-machined hardened steel ring gear features starter-pinion teeth pressed onto the outer edge of a single-mass “RS” or lightweight flywheel. It’s the critical interface between the starter motor and the engine — the starter’s small pinion engages these teeth to crank the engine during start-up.
Technical Summary
- Function: Transfers starter motor rotation to the flywheel for engine cranking.
- Location: Pressed or shrink-fitted onto the outer diameter of the flywheel.
- Construction: Heat-treated, hardened steel with precision-machined teeth for maximum strength and wear resistance.
- OEM Part Number: 964.114.143.31 (also listed as 96411414331).
- Applications: Designed for RS, single-mass, or lightweight flywheels used in various Porsche 964 and 993 models, and select 996/997 GT3 and GT2 variants. Not compatible with dual-mass flywheels.

Why You Should Replace Your Ring Gear
1. Damaged or Missing Teeth
Grinding, rough engagement, or failed starts often result from chipped, flattened, or missing teeth on the ring gear. When the teeth are damaged, the starter pinion can’t engage properly, leading to grinding or slipping during start-up.
2. Wear, Pitting, or Corrosion
Over time, surface wear, rust, or pitting can develop due to age or moisture exposure. These issues reduce engagement quality and increase wear on both the starter and ring gear.
3. Loose or Shifted Ring Gear
Although ring gears are press-fitted, heat cycles or improper installation can cause them to loosen or shift. A loose ring gear creates noise, accelerates wear, and poses a potential safety hazard.
4. During Flywheel or Clutch Service
Whenever the flywheel is removed for clutch replacement or resurfacing, it’s best practice to inspect the ring gear closely. Replace it if you find any damage or wear—it’s far cheaper than removing the transmission again later.
5. Starter or Pinion Replacement or Upgrades
If you’re installing a new or upgraded starter—or have had a starter failure that damaged the pinion—inspect and replace the ring gear at the same time to ensure proper engagement and reliable operation.

This is a premium wiper-blade pair engineered for the front windshield. The blades provide consistent, streak-free wiping, proper contact across the windshield curvature, and correct fitment with the Porsche wiper arm mounting system.
Over time, wiper blades decline due to UV exposure, rubber degradation, wear and climate. A worn blade can cause streaking, reduced visibility in rain, noise or even scratching of the windshield.
Replace your blades when:
• You notice streaks or smears during wiping
• The rubber edge appears cracked, hard or uneven
• You’re preparing your Porsche for rainy or winter seasons
Installing a matched set of OE Match blades ensures both sides wipe evenly, improves driver visibility and maintains the aesthetic integrity of your classic Porsche.
