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

Ignition Lead Sets – Reliable Spark Transfer for Peak Porsche Performance
Ignition lead sets, also known as spark plug wire sets, play a crucial role in your Porsche’s ignition system. They carry high-voltage current from the ignition coil or distributor to the spark plugs, ensuring a strong and consistent spark for optimal combustion and performance.
At Design911, we offer a wide range of genuine and high-quality ignition lead sets for 911, 944, 928 and other Porsche models. Each set is designed for precise fitment, superior conductivity, and exceptional heat resistance — maintaining dependable performance under all driving conditions.
What Do Ignition Lead Sets Do?
Ignition leads are responsible for delivering the electrical
charge required to ignite the fuel-air mixture inside your Porsche’s engine.
Their functions include:
- Transmitting
high-voltage current from the ignition coil or distributor to the
spark plugs.
- Ensuring
consistent spark delivery for smooth combustion.
- Reducing
electrical resistance for improved efficiency and performance.
- Providing insulation and durability against heat and vibration.
High-quality ignition leads are essential for maintaining strong ignition performance, quick starts, and efficient fuel use in all Porsche engines.
Why Do Ignition Leads Fail?
Over time, ignition leads experience electrical and thermal
wear, reducing their ability to deliver a strong spark. Common causes of
failure include:
- Cracked
insulation from heat or age.
- Corrosion
or oxidation on terminals.
- High
resistance due to degraded internal conductors.
- Moisture
or oil contamination causing arcing or short circuits.
- Mechanical stress from engine vibration or poor routing.
Symptoms of failing ignition leads include engine misfires, rough idling, reduced acceleration, hard starting, and increased fuel consumption.
Why Replace Worn Ignition Leads?
Old or damaged ignition leads can cause weak or inconsistent spark delivery, leading to reduced engine performance and fuel efficiency. Replacing them restores proper combustion and smooth operation.
Benefits of replacement include:
- Improved throttle response and power output.
- Smoother engine idle and reduced misfires.
- Enhanced fuel economy and lower emissions.
- Reliable, manufacturer-quality ignition performance.
Our ignition lead sets are manufactured from high-grade silicone, Kevlar reinforcement, and precision terminals, ensuring maximum conductivity, flexibility, and long-term durability.
