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 refrigerant pressure line for Porsche 964 models up to 1992. Intended for replacement of damaged or leaking pipework in the air conditioning circuit.
Fits:
Porsche 964 >>1992
Diagram ref no 17
What This Product Does
This pipe carries pressurised refrigerant within the A/C system. An intact line helps keep the circuit sealed, allowing refrigerant to circulate without escaping through damaged pipework.
Functions
- Provides a passage for refrigerant within the pressure circuit.
- Forms part of the sealed connection between air conditioning components.
Technical Details
- Brand: OE Match.
- Supplied product reference: 96457309304.
- Internal diagram identifies pressure line 96457309300 in the front refrigerant circuit.
- Internal application note: -92, indicating use up to 1992.
Symptoms of Fault
- Cooling deteriorates again after refrigerant replenishment.
- Oil traces or leak-detection dye appear around pipe connections.
- Visible corrosion, cracks or rubbing damage affect the line.
- A substantial leak may produce a hissing sound.
These signs warrant inspection; poor cooling alone does not confirm that this particular line is faulty.
Why Replacement Matters
A cracked, corroded or leaking line needs repair rather than repeated refrigerant replenishment. Replacing confirmed faulty pipework addresses the escape route. Inspect adjoining connections and renew the relevant seals during installation.
FAQs
- Could new seals be sufficient?
If leakage is confined to a connection and the pipe remains sound, seal replacement may resolve it. Damage to the pipe itself requires separate attention. - Will replenishing refrigerant fix a leak?
No. Refrigerant can escape again unless the source of the leak is repaired. - What should be checked before fitting?
Confirm the vehicle application, up-to-1992 restriction, connection details and relevant part references.

OE Match exhaust hex nut designed as a direct-fit replacement fastener for the exhaust heat exchanger studs on classic Porsche 911 (1965–1998) engines. This hex nut secures the heat exchanger to the cylinder heads and exhaust studs, ensuring reliable fastening in the high-heat exhaust system environment.
Sold individually. 4, 5, or 6 required, depending on car model.
Fits:
Porsche 911 1965-89 (6 for both heat exchangers)
Porsche 964 Carrera 1989-94 (4 for both heat exchangers)
Porsche 993 Carrera 1994-98 (5 for both heat exchangers)
Porsche 993 Turbo 1994-98 (4 for both heat exchangers)

The hex nut is used in conjunction with the heat exchanger studs and exhaust system components to clamp the exhaust heat exchanger securely in place and maintain a sealed joint between mating parts.
The exhaust hex nut’s role may seem simple, but it’s critical to the integrity of the heat exchanger and exhaust assembly:
• Secures the heat exchanger studs to the engine block/exhaust flange
• Maintains clamp force under thermal cycling and vibration
• Helps prevent exhaust leaks at the heat exchanger interface
• Resists corrosion and heat exposure typical of exhaust temperatures.
Proper fastening ensures that the heat exchanger - which routes exhaust gasses away from the cylinders and towards the muffler system - remains sealed and aligned throughout engine operation.
Function
• Fastening: Threads onto the exhaust/heat exchanger stud to clamp components
• Retention: Holds joint integrity under vibration and thermal expansion
• Seal support: Helps maintain exhaust system seal and prevents leaks
• Heat resilience: Engineered from heat-resistant material for exhaust applications.
Worn, rusted, or missing hex nuts can lead to loose exhaust joints, exhaust leaks, poor performance, and increased noise.
Although small, exhaust hex nuts play a critical role in maintaining proper heat exchanger sealing and long-term exhaust durability. Over time, exposure to extreme heat and exhaust gases can cause nuts to corrode, seize, lose clamping force, or break during removal, leading to exhaust leaks and compromised sealing at the cylinder head. Replacing them with OE Match hex nuts restores secure fastening, helps prevent leaks, protects surrounding engine components from excess heat, and preserves overall exhaust performance.
Exhaust hex nuts should be replaced whenever the heat exchanger or exhaust system is removed, if the existing nuts are corroded, seized, rounded, or damaged, or when exhaust leaks are detected at the heat exchanger interface.
