🔌 Function

The ignition coil stores and releases high-voltage energy to the distributor so spark can be delivered to the plugs at the correct time.

Common signs of failure:

• No spark

• Weak yellow spark

• Engine starts then stalls when warm

• Misfire under load

• Backfiring or rough idle

• Coil becomes excessively hot

• Cracked tower, oil leakage or corroded terminals

📦 Condition

• Genuine used part

• Removed from running engine where applicable

• In good working condition unless otherwise stated
