Ignition Lead (5 METER). Porsche 911 / 914 1965-76

Ignition Lead (5 METER).
Restore the proper operation of your Porsche ignition system with this genuine OEM ignition lead. Designed to carry high-voltage current safely and reliably from the ignition coil/distributor to the spark plug, it ensures each cylinder receives the correct spark at the correct time. Ideal replacement if your existing lead is aged, damaged or under-performing.

Fits:

• Porsche 911 1965-1968 2.0L / 912 SWB (F)
• Porsche 911 1970-1973 2.2L / 2.4L / 2.7L RS LWB (F)
• Porsche 911 1974-1975 2.7L
• Porsche 911 1975-1975 3.0L Turbo (930)
• Porsche 914 (1970-1976)

What This Product Does:

• An ignition lead carries the high-voltage current from the ignition coil or distributor to the spark plug, enabling the spark required for combustion in the cylinder.
• It must handle high voltage (many thousands of volts), resist heat, oil, oil-vapour, and avoid interference or cross-firing between adjacent leads.
• Using the correct OEM lead ensures proper electrical characteristics (resistance, insulation, length) and prevents mis-fires, poor engine performance or electrical noise/interference.

Symptoms & Signs It May Need Replacement:

• Mis-fires, rough idle or intermittent spark — if one cylinder is mis-firing and leads are very old or cracked, the lead may be the culprit.
  
• Visible damage: cracked insulation, oil soaked lead, brittle rubber/silicone, or the lead ends corroded or loose.
  
• Hard starting or stumbling under load — old/high resistance leads degrade under load and heat.
  
• Increased engine electronic noise or interference — since bad leads can leak voltage and cause interference with sensors or ignition components.
  
  

Why Replacement Matters:

• Performance & reliability: Ensures the ignition system can deliver reliable voltage to each spark plug every time.
  
• Prevention of further damage: A failing lead can lead to mis-fire, which can damage catalytic converter, reduce fuel economy, allow unburnt fuel, etc.
  
• Ease of diagnosis: By replacing leads with known-good OEM units, you eliminate a common variable when diagnosing ignition/engine issues.
