• Spark loss caused by a failing coil-on-plug unit

Installation Notes and Tips

Confirm the connector style, terminal count, and engine application before installation. Inspect the coil boot, spark plug condition, and wiring connector for heat damage, corrosion, or oil contamination before replacing the coil. Clear diagnostic trouble codes after installation and verify engine operation with a road test.
