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.

The HT (High Tension) leads play a vital role within the ignition system by carrying thousands of volts generated by the ignition coil to the spark plugs. This electrical energy creates the spark that ignites the air and fuel mixture inside each cylinder, allowing the engine to produce smooth, efficient and reliable power.
Manufactured to OE Match standards, these ignition leads provide excellent insulation, precise fitment and dependable electrical performance, making them ideal for routine servicing, engine rebuilds or ignition system restoration.
Why Do Ignition HT Leads Fail?
HT leads operate in one of the harshest environments on the vehicle. Positioned around the engine, they are constantly exposed to high temperatures, vibration, oil vapours and moisture. Over time, the insulation naturally deteriorates, allowing electrical current to leak before it reaches the spark plug.
The internal conductor can also degrade with age, increasing electrical resistance and reducing spark energy. Cracked insulation, hardened boots or corrosion at the terminals can all contribute to ignition problems, particularly under heavy engine load or in damp conditions.
On turbocharged engines such as the Porsche 930, where higher cylinder pressures require a stronger ignition spark, deteriorated HT leads can become even more noticeable, leading to reduced performance and poor combustion.
When Should HT Leads Be Replaced?
Ignition leads should be inspected during routine servicing and replaced whenever there are signs of deterioration or ignition performance begins to suffer.
Common signs include:
- Engine misfires Rough idle
- Hesitation under acceleration
- Difficult starting
- Reduced fuel economy
- Visible cracks or damage to the insulation
- Hardened or split rubber boots
- Corroded electrical terminals
- During a complete ignition tune-up or engine rebuild
Replacing the complete lead set ensures balanced ignition performance across all cylinders and helps maximise the lifespan of the spark plugs, distributor cap and rotor arm.
Key Features
- Complete ignition HT lead set
- Restores efficient spark delivery
- High-quality insulation for reliable performance
- Precision manufactured for accurate fit
- Helps eliminate ignition misfires and rough running
- Ideal for servicing, restoration and engine rebuilds
Porsche 911 SC & 930 Turbo Ignition Components
A healthy ignition system is essential to maintaining the performance and character of every air-cooled Porsche engine. The HT lead set forms the link between the ignition coil, distributor and spark plugs, ensuring each cylinder receives the correct spark at precisely the right time.
As ignition components age together, replacing the HT leads alongside the spark plugs, distributor cap and rotor arm helps restore the crisp throttle response, smooth idle and dependable reliability expected from the Porsche flat-six.
Whether you're maintaining a regularly driven 911 SC or preserving the performance of a classic 930 Turbo, renewing ageing ignition components is an important part of preventative maintenance.
Benefits of Replacing the HT Lead Set
- Restores full ignition performance
- Delivers stronger, more consistent spark energy
- Improves starting and idle quality
- Helps eliminate ignition misfires
- Supports improved fuel efficiency
- Reduces stress on other ignition components
- Ideal for complete ignition servicing
