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.

Coolant hoses operate under constant heat and pressure. Over time the rubber can become brittle, swell or crack due to thermal cycling and coolant exposure. A deteriorated hose may cause coolant leaks or reduced cooling efficiency, potentially leading to engine overheating. Replacing worn hoses ensures the cooling system maintains proper pressure and flow.
When to Replace. Consider replacing the hose if you notice:
• Visible cracks, swelling or deterioration in the rubber
• Coolant leaks around the thermostat connection
• Loss of coolant pressure or overheating issues
• During cooling system overhaul or thermostat replacement.

Moulded to the same dimensions as the original Porsche part, this holder grips the leads firmly. It’s ideal when refreshing ignition components, fitting new leads, or restoring the look of a classic flat-six. Many applications use several holders per engine.
Function:
• Clips around multiple ignition leads to hold them in a fixed bundle
• Reduces vibration-induced movement that can cause insulation wear
• Aids easy maintenance by keeping lead routing clear and repeatable
Old ignition cable holders often become brittle, warped or broken, leaving plug leads to sag, touch hot surfaces or rub on engine parts. That can lead to:
• Damaged HT lead insulation and potential misfires
• Untidy, hard-to-service lead routing
Fitting fresh holders restores safe, neat lead routing and completes any ignition refresh or classic engine-bay restoration.

Diagram ref no 37
Designed for front brake calipers with 38mm pistons, this scraper ring helps protect the piston and surrounding sealing area from brake dust, dirt, moisture and road contamination.
A damaged or deteriorated scraper ring can allow contaminants to accumulate around the brake piston, increasing the risk of corrosion, sticking pistons and reduced braking performance.
What Does the Brake Caliper Piston Scraper Ring Do?
The scraper ring forms a protective barrier around the brake caliper piston, helping prevent dirt, moisture and brake dust from entering the area between the piston and caliper body.
As the piston moves during braking, the scraper ring helps keep its exposed surface protected from contamination.
This is particularly important on high-performance braking systems such as those fitted to the Porsche 911 Turbo, where brake components are exposed to considerable heat and demanding operating conditions.
The scraper ring is separate from the internal hydraulic piston seal, which is responsible for retaining brake fluid pressure.
Why Does It Fail?
Brake caliper piston scraper rings are exposed to high temperatures, road debris and repeated piston movement.
Common causes of deterioration include:
Age-related hardening or cracking Heat damage from prolonged or heavy braking Contamination from road dirt and brake dust Moisture and corrosion around the piston Damage during brake pad replacement Incorrect installation or previous caliper repairs General wear after years of serviceOnce damaged, the scraper ring may no longer provide effective protection against contamination.
When Should It Be Replaced?
Replacement is recommended whenever the scraper ring becomes cracked, torn, hardened, loose or otherwise damaged.
Common signs that inspection or replacement may be necessary include:
Visible deterioration around the brake piston Corrosion developing on the piston surface Sticking or difficult-to-retract brake pistons Uneven brake pad wear Brake drag or overheating Contamination around the piston and caliper boreThe scraper rings should also be inspected during brake caliper refurbishment, piston replacement or a complete braking system restoration.
Related Brake Caliper Components
For a complete front brake caliper overhaul, the following components may also require replacement:
Front brake caliper piston sealing ring – 93035155501 Front brake caliper scraper ring – 93035154700 Front brake caliper seal repair kit – PO-930FBCKITThe front caliper repair kit contains four scraper rings and four hydraulic piston sealing rings, sufficient to rebuild one front caliper.
Installation Notes
Inspect the brake caliper piston for corrosion, scoring or other damage before fitting the replacement scraper ring.
A new scraper ring will not correct problems caused by a damaged piston or defective hydraulic seal.
Ensure all components are correctly seated and installed using the appropriate Porsche brake caliper servicing procedure.
Brake caliper repairs should be carried out by a suitably qualified technician, with the braking system thoroughly checked before the vehicle is returned to service.
Porsche 911 Turbo 930 Brake Caliper Scraper Rings, Piston Seals & Repair Parts
The front brake calipers fitted to Porsche 911 Turbo 930 models rely on correctly functioning pistons, hydraulic seals and protective scraper rings to maintain reliable braking performance.
Over time, exposure to heat, moisture and road contamination can cause the original scraper rings to deteriorate, allowing dirt to reach the brake piston surface and potentially contribute to corrosion or restricted piston movement.
OE Match brake caliper piston scraper ring provides a replacement solution for Porsche 911 Turbo 3.3L models manufactured between 1978 and 1989, front calipers with 38mm pistons.
Replacing damaged scraper rings during routine brake maintenance or caliper refurbishment helps protect internal components and supports long-term braking system reliability.

Manufactured from precision CNC-machined aluminium alloy, these collapsible oil tubes offer improved durability and easier installation compared with conventional rigid oil return pipes.
Supplied as a individually with replacement seals, four kits are needed per engine and these are ideal for repairing engine oil leaks, replacing ageing oil return pipes or carrying out a comprehensive engine restoration.
What Does the Collapsible Oil Tube Do?
The oil return tubes allow engine oil to drain from the cylinder head and valve gear areas back towards the engine crankcase.
This return flow is an important part of the engine's lubrication system, allowing oil to circulate correctly while preventing it from escaping through the engine casing.
The collapsible design allows the tubes to be compressed during installation and extended into position, making replacement considerably easier than fitting conventional one-piece rigid tubes.
Why Do Oil Return Tubes Fail?
Original oil return tubes and their seals are exposed to repeated heating and cooling cycles, engine vibration and general ageing.
Common causes of failure include:
Hardened or deteriorated rubber O-ring seals Corrosion of original metal oil tubes Cracked or damaged tube sections Distortion caused by previous repairs Incorrect installation or damaged sealing surfaces Long-term exposure to engine heat and oil contaminationIn many cases, oil leaks develop because the original seals lose their flexibility and can no longer maintain an effective seal.
When Should They Be Replaced?
Replacement is recommended when the oil return tubes show visible corrosion, physical damage or signs of oil leakage.
Common symptoms include:
Oil dripping from beneath the engine Wet or oily areas around the return tubes Burning oil smells caused by oil reaching hot exhaust components Increasing oil consumption due to external leakage Deteriorated or hardened oil tube sealsThe tubes should also be inspected during engine rebuilding, cylinder head servicing or restoration work.
Why Upgrade to CNC Alloy Collapsible Oil Tubes?
The CNC-machined aluminium alloy construction provides a durable replacement for ageing original components.
Unlike rigid oil return tubes, the collapsible design allows the replacement tubes to be fitted without the extensive dismantling normally associated with removing fixed-length tubes.
This makes them particularly useful for repairing oil leaks while the engine remains assembled.
Replacing all four tubes together also provides an opportunity to renew the complete set of seals, reducing the likelihood of further leaks from other ageing tubes.
Installation Notes
Before installation, inspect the oil return tube mounting points and sealing surfaces for damage or contamination.
Lubricate the replacement seals with a suitable lubricant, install the tubes in their compressed position and extend them fully into the correct mounting locations.
Ensure the tubes are correctly seated and secured according to the manufacturer's instructions.
Following installation, run the engine and inspect the repaired areas for oil leaks.
Porsche 911, 964 & 993 Collapsible Oil Return Tubes and Engine Lubrication Parts
The engine oil return tubes are essential components of the air-cooled Porsche flat-six lubrication system, allowing oil to return from the cylinder head assemblies to the crankcase.

The MFI pump drive gear is mounted on the left-hand camshaft and drives the toothed belt connected to the mechanical fuel injection pump.
As the engine rotates, the camshaft turns the drive gear, which operates the injection pump in synchronisation with the engine.
This allows the mechanical injection system to deliver fuel at the correct point in the engine's operating cycle.
Why Does It Fail?
Although designed for long service life, the drive gear can deteriorate through age, wear or damage.
Common causes include:
- Worn or damaged gear teeth
- Corrosion or surface deterioration
- Incorrect toothed belt tension or alignment
- Damage during engine or injection system repairs
- Wear or damage to the gear mounting arrangement
- Long-term mechanical stress
A damaged gear can affect the operation of the injection pump drive system and may eventually cause the toothed belt to slip or lose correct engagement.
When Should It Be Replaced?
Replacement is recommended when the original drive gear shows visible tooth wear, cracking, corrosion or mechanical damage.
The gear should also be inspected during:
Mechanical fuel injection pump servicing MFI drive belt replacement Camshaft removal or replacement Engine rebuilding or restoration Investigation of injection pump drive problemsIncorrect injection pump timing, irregular engine operation or damage to the MFI drive belt may indicate a problem within the drive system and should prompt further inspection.
Confirm compatibility using the original part number and engine specification before ordering.
Installation Notes
Correct installation and alignment are essential for reliable mechanical fuel injection operation.
Inspect the toothed drive belt, associated injection pump gear, mounting hardware and related components for wear or damage.
Following installation, check the drive belt tension and mechanical fuel injection pump timing according to the Porsche workshop procedure.
Porsche 911 Mechanical Fuel Injection Pump Drive Gears & MFI Components
The mechanical fuel injection system fitted to selected early Porsche 911 models relies on accurate mechanical synchronisation between the engine and Bosch injection pump.
The left-hand camshaft drive gear is an essential component of this arrangement, transmitting rotational movement through the toothed belt to operate the fuel injection pump.
Over time, wear, corrosion or damage to the drive gear can compromise the reliability of the MFI drive system.

Diagram ref no 21
This valve regulates the flow of refrigerant entering the evaporator, helping the air conditioning system maintain the correct operating pressure and produce consistently cool air inside the vehicle.
A faulty or restricted expansion valve can significantly reduce cooling efficiency, making replacement an important part of restoring the air conditioning system on a classic Porsche 911.
What Does the Air Conditioning Expansion Valve Do?
The expansion valve controls the amount of high-pressure liquid refrigerant entering the evaporator.
As refrigerant passes through the valve, its pressure drops, allowing it to absorb heat from the cabin air as it travels through the evaporator.
By regulating refrigerant flow, the valve helps maintain efficient cooling and protects the system against incorrect refrigerant distribution.
Why Does It Fail?
Over time, the expansion valve can deteriorate due to age, internal contamination or moisture entering the air conditioning system.
Common causes of failure include:
- Internal blockage from dirt or debris
- Corrosion caused by moisture contamination
- Wear or sticking of internal valve components
- Damage to the temperature-sensing mechanism
- Contamination following compressor failure
When Should It Be Replaced?
A faulty expansion valve may cause:
Poor or inconsistent air conditioning performance Warm air from the ventilation outlets Evaporator icing or abnormal refrigerant pressures Intermittent cooling Incorrect refrigerant flow through the evaporatorReplacement may also be advisable during a major air conditioning overhaul, particularly if the original valve is contaminated or damaged.
These symptoms can have several causes, so the system should be diagnosed before replacing the valve.
Installation & Maintenance Notes
The air conditioning system must be professionally discharged using approved refrigerant recovery equipment before the expansion valve is removed.
Inspect the surrounding pipework, seals and evaporator connections for contamination or damage. Replace disturbed seals as required and use only compatible components and lubricants.
Following installation, the system should be evacuated, leak-tested and recharged with the correct refrigerant quantity.
Porsche 911 Air Conditioning Expansion Valves & Climate Control Parts
The air conditioning expansion valve is an essential component of the Porsche 911 refrigerant circuit, controlling refrigerant flow into the evaporator to provide effective cabin cooling.
On classic Porsche 911 Carrera models, ageing air conditioning components can contribute to poor cooling performance, particularly when valves become restricted or internal seals and control mechanisms deteriorate.
