Product Details

What It Helps Fix

• Engine misfire caused by a weak or failed ignition coil
• Hard starting related to inconsistent spark output
• Rough idle from ignition breakdown under load
• Loss of power during acceleration
• Check engine light conditions tied to ignition coil faults

Installation Notes and Tips

Verify connector style, terminal count, and engine application before installation. Inspect the spark plug, coil boot area, and wiring connector for heat damage, corrosion, or oil contamination before fitting the new coil. For best results, replace the coil only after confirming the underlying ignition issue has been diagnosed correctly.

Quality Assurance

Delphi builds this ignition coil using OE heritage and application knowledge developed through decades of supplying original equipment to major automakers. That background supports consistent fitment and service replacement confidence for Hyundai and Kia ignition repairs.
