What This Product Does
HT means high tension: these cables conduct the ignition system’s high voltage to the spark plugs, where it initiates combustion. Insulation around each conductor helps contain that voltage along its intended path.
Functions
- Conducts ignition voltage to the plugs.
- Insulates the electrical path between ignition connections.
- Connects the ignition components through dedicated leads.
Technical Details
- Supplied quantity: five cables.
- Application identifiers include XJ, XK and M31.03; refer to the individual fitment entries.
Symptoms of Fault
- Uneven running or misfiring during acceleration.
- Starting difficulties or hesitation.
- Ignition problems that worsen in wet conditions.
- Split, hardened or otherwise damaged insulation.
- Loose connections or corroded terminals.
- Evidence of electrical tracking around cables or boots.
Why Replacement Matters
Heat, vibration and contamination can deteriorate ignition cables. Damaged insulation, degraded conductors or corroded connections can interrupt the intended electrical path. Renewing leads with a confirmed fault addresses that deterioration; inspect the plugs, distributor connections and cable routing at the same time rather than assuming every misfire originates in the leads.
FAQs
How many cables are included?
The supplied set contains five cables.
Can one faulty lead affect a single cylinder?
Yes. A defective individual cable can cause a cylinder-specific ignition problem, although other ignition or fuelling faults can produce similar symptoms.
Does a resistance test confirm cable condition?
A multimeter can identify some conductor faults, but a resistance reading alone does not establish whether the insulation remains sound.
Should the spark plugs also be changed?
Inspect their condition and service history. Replace worn plugs as required rather than assuming that new plugs are necessary whenever leads are renewed.

OE Match ignition HT lead set, these high-tension cables form part of the engine’s spark-delivery system.
Fits
- Porsche 924 2.0L Carrera GT M31.50 1980-86
Check fitment for your specific vehicle (model, year, engine) before ordering.
What This Product Does
HT means high tension: the voltage used by the ignition system to generate a spark. The leads carry this electrical pulse towards the plugs, where it ignites the mixture within each cylinder. Their insulation helps keep the voltage within the intended electrical path.
Functions
- Conduct ignition pulses to the spark plugs.
- Insulate the high-voltage conductors.
- Provide connections between ignition components.
Technical Details
- Product type: ignition HT lead set.
- Brand: OE Match.
- Listed engine capacity: 2.0L.
- Carrera GT engine identification: M31.50.
Symptoms of Fault
- Uneven idling or hesitation during acceleration.
- Misfiring when the engine is loaded or conditions are damp.
- Insulation that has split, stiffened or developed tracking marks.
- Corroded terminals or poorly seated connection boots.
- Resistance measurements that indicate conductor deterioration.
Why Replacement Matters
Age, engine heat and contamination can damage lead insulation or electrical connections. Once deterioration is confirmed, replacing the affected lead set addresses an identified source of ignition leakage or excessive resistance. Check the plugs, distributor connections and cable routing as part of the same repair; similar running symptoms can have other causes.
FAQs
Could one faulty cable affect only one cylinder?
Yes. An individual lead can deteriorate independently, although the remaining cables may have experienced similar ageing.
Is a resistance measurement enough to confirm condition?
No. It can reveal conductor faults, but may not expose insulation leakage. Include inspection of the insulation, terminals and boots.
Must the spark plugs also be changed?
Inspect their condition and service history first. Renew worn plugs where required rather than assuming that replacing cables alone will resolve every misfire.

This OE Match Ignition HT Lead Set is a complete high-tension ignition cable kit designed for Porsche 924 Turbo models. It delivers electrical current from the ignition system to the engine’s spark plugs.
Fits:
Porsche 924 Turbo 1979 - 1982
This OE match ignition HT lead set is a direct replacement for the original Porsche ignition wiring used in the 924 Turbo. Designed to factory specifications, the set includes all necessary leads to connect the ignition coil and distributor to each cylinder.
This ignition lead set transmits high-voltage electrical current from the ignition coil or distributor to the spark plugs, ensuring a strong and consistent spark for combustion.
By maintaining reliable spark delivery, it supports smooth engine operation, efficient fuel combustion, and consistent performance.
Function
• Transfers high-voltage current to spark plugs
• Ensures consistent and reliable ignition spark
• Maintains proper combustion efficiency
• Reduces electrical resistance and signal loss
• Provides insulation against heat, moisture, and vibration
Over time, ignition leads degrade due to heat, age, and electrical stress. This can cause weak spark delivery, leading to misfires, poor performance, and increased fuel consumption. Replacing worn leads restores ignition efficiency, improves engine smoothness, and ensures reliable starting and performance.
When to replace
• Engine misfires or rough idle
• Difficulty starting, especially in cold or damp conditions
• Visible cracks, wear, or brittle insulation
• Increased fuel consumption or poor performance
• During tune-up or ignition system service

OEMatch Ignition Lead Sets — Fit, Function, Confidence
OEMatch ignition lead sets provide vehicle-specific replacements for Porsche models, intended to restore consistent spark delivery and predictable engine response. They are a practical option for engines affected by worn leads that cause misfires, rough idle or difficult starting, and are made to original-spec dimensions where applicable.
Available Types
- Complete vehicle-specific kits including boots and terminals
- Silicone-insulated high-voltage leads for improved heat resistance
- Replacement leads supplied by axle or as complete engine sets
Understanding OEMatch Ignition Lead Sets
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original ignition lead sets. OE (Original Equipment) refers to parts matching original specifications for the ignition lead sets and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM ignition lead sets engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models.
Ignition lead sets carry high-voltage current from the coil or distributor to each spark plug, delivering the spark needed for combustion. Worn or damaged leads increase resistance or allow arcing, producing misfires, rough idle and poor throttle response. OEMatch supplies a broad range of Porsche parts and maintains an extensive parts catalogue with thousands of part numbers and OE cross-references, supporting maintenance and restoration across many Porsche models.
Benefits Include
- Restored ignition consistency to reduce misfires and rough running
- Improved starting and throttle response
- Durable insulation and terminals to resist heat and contamination
Why Ignition Lead Sets Wear and Fail
- Heat and age causing cracked or hardened insulation
- Corrosion or oxidation on terminals increasing resistance
- Moisture or oil contamination leading to arcing or short circuits
- Mechanical stress from vibration or incorrect routing
The Importance of Replacing with OEMatch Ignition Lead Sets
Faulty leads can impair combustion and increase emissions, so timely replacement restores reliable spark delivery and consistent engine behaviour. Choosing parts prepared for Porsche applications helps preserve original routing, terminal types and heat resistance characteristics, reducing the risk of recurrent faults and supporting predictable vehicle performance.
Advantages
- Vehicle-specific fit and terminal styles to match factory connections
- Materials selected for heat and vibration resistance
- Complete kits simplify renewal by including boots and terminals where required
