What should I check before replacing my vehicle’s ignition coils?

Confirm the OEM part numbers or cross-reference fitment with your vehicle’s year, engine displacement, and VIN where possible. Inspect spark plugs and wiring harness condition; replacing worn plugs at the same time helps ensure optimal performance.

• Verify compatibility using listed OEM numbers like UF-549, 22448JA00A, and others
• Replace spark plugs if they show wear, fouling, or incorrect gap
• Check ignition harness connectors for corrosion or damage before installation
