ThunderSpark 921-2123 Ignition Coil - Walker O2-921-2123

Single Coil

The ignition coil transforms the vehicle's battery voltage into the high voltage needed to fire the spark plug and ignite the air/fuel mixture in the cylinder. Signs of failure include: a check engine light with a misfire code on a specific cylinder, a rough idle or lack of power, reduced fuel economy, or a coil that fails a resistance test. Replace a failed ignition coil to restore complete, consistent firing on every cylinder.
