ignition lead 87161466760

An ignition lead (or ignition cable) is a crucial component in an internal combustion engine’s ignition system. It conducts electrical current from the ignition coil to the spark plugs, enabling the spark necessary for igniting the air-fuel mixture in the engine cylinders.

Key Aspects of Ignition Leads:

1. Purpose:

• Conduct Electricity: Transfers high-voltage electricity from the ignition coil to the spark plugs.
• Ignition Timing: Ensures that the spark plugs fire at the correct time to optimize engine performance.

2. Components:

• Wire Core: Made from high-voltage-resistant materials such as silicone or rubber, often with a conductive core, like carbon or metal strands.
• Insulation: Provides electrical insulation to prevent short circuits and to protect against heat and vibration.
• Connectors: Ends of the leads have connectors that attach to the ignition coil and spark plugs. These can be clip-on or screw-on, depending on the system.

3. Types:

• Standard Ignition Leads: Simple, usually with a single layer of insulation.
• Resistor Ignition Leads: Include a resistor to reduce electromagnetic interference (EMI) and radio frequency interference (RFI).
• High-Performance Leads: Designed for high-energy ignition systems, often with advanced insulation and materials to handle higher temperatures and voltages.

4. Common Issues:

• Wear and Tear: Over time, leads can degrade due to heat, vibration, and exposure to engine fluids.
• Cracks or Breaks: Visible damage to the insulation or core can lead to misfires or reduced engine performance.
• Electromagnetic Interference: Faulty leads can cause electrical noise affecting engine performance and radio reception.

5. Maintenance:

• Inspection: Regularly check ignition leads for signs of wear, damage, or corrosion.
• Replacement: If leads show signs of damage or performance issues, replace them with compatible parts. Using the correct part number ensures proper fit and function.
