How to get broken ignition coil pieces out of the spark plug tube
Bits of a shattered ignition coil can fall down into the spark plug cavity, risking serious internal damage if they drop further. While people try various suction and retrieval methods to clear the chamber, the presence of the spark plug itself can sometimes block debris from entering the engine cylinder.
