Ignition Coil with Extension Lead (Spark Coil & Wire Set) ⚡

This ignition coil and extension wire set is a key part of the engine’s spark system. It is needed to create a strong high-voltage pulse and deliver it cleanly to the spark plug. Without a healthy coil and lead, the air/fuel mix will not ignite at the right moment, so power, fuel economy, and smooth idle all suffer.

How it works

The coil converts 12V battery power into thousands of volts. The extension lead carries that voltage to the spark plug without leaking or arcing. The ECU triggers the coil precisely; the coil “charges” and then releases energy in a sharp burst, firing the plug. Good insulation inside the boot/lead prevents misfire under load and in wet conditions.

Why replacement matters

A weak or cracked coil/lead can cause:

• Misfire, shaking idle, hesitation on acceleration
• Hard starting, poor fuel mileage, loss of power
• Check Engine light (common misfire codes)
• Unburnt fuel overheating the catalytic converter

When it’s broken

If the coil windings break down or the wire/boot carbon-tracks, voltage escapes to ground instead of the plug. The cylinder drops out, the engine runs rough, and long-term driving can damage coils, plugs, and the catalyst. Replace promptly for reliable spark and safer emissions.
