Ignition Lead Sets
The ignition HT lead set is a full set of spark-plug cables built for classic air-cooled Porsche engines - Porsche 912, early Porsche 914 series and Porsche 356 (A, B, C).
Fits:
Porsche 912 1.6L 1965 - 1968
Porsche 356 A 1600 / 356 A 1600 S 1950 - 1959
Porsche 356 B / 356 C 1960 - 1965
Porsche 914 1.7L 01.1969 - 12.1973
Porsche 914 1.8L 08.1973 - 02.1976
Porsche 914 2.0L 01.1972 - 12.1975
These ignition leads transmit high-voltage current from the distributor (or ignition coil) to each spark plug. They are constructed with premium insulation and conductor materials to ensure strong, consistent spark delivery, maximize ignition reliability, and resist temperature, oil, and engine-bay contaminants - essential for proper combustion, smooth idle, reliable starts, and optimal performance.
• Position: Spark plug wiring - HT lead set connecting distributor/coil to spark plugs on engine cylinders.
• Function: Delivers high-voltage current to spark plugs for ignition; ensures reliable spark timing and combustion, supports smooth engine start, idle, and throttle response.
• Construction: High-insulation HT cables with durable boots, correct length and connections for direct-fit replacement, built to OE specification for resistance to heat, oil and vibration.
Accurate, strong spark delivery is fundamental to engine performance, fuel efficiency and smooth running - particularly in older air-cooled engines, where maintenance and correct ignition timing are critical. Faulty, brittle or incorrect ignition leads can cause misfires, poor idle, hard starts, rough running or even engine damage over time.
By replacing old or worn wiring with a correctly specified HT lead set like this one, you restore reliable ignition, reduce misfires, ensure clean combustion, improve throttle response, and maintain the overall integrity and reliability of the engine ignition system.

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.
