🔌 Function

The ignition coil converts ignition-system voltage into high-voltage spark output for the spark plugs.

Common signs of failure:

• No spark on paired cylinders

• Weak or intermittent spark

• Engine misfire

• Rough idle

• Loss of power under load

• Heat-related spark failure

• Cracked coil body or damaged plug leads

• Spark returns when a known-good coil is fitted

📦 Condition

• Genuine used part

• Removed from running engine where applicable

• In good working condition unless otherwise stated
