What It Helps Address

• Hard starting related to weak ignition transfer
• Rough idle from inconsistent spark delivery
• Voltage leakage from cracked or worn wire insulation

Installation Notes and Tips

Verify the wire routing against the original Hyundai Accent layout before removal. Match each lead to the correct cylinder and confirm the 120-degree angled boot seats fully at the spark plug end. Inspect coil and distributor connections for corrosion or carbon tracking before installing the new set.

For best results, replace ignition wires when the engine is cool and avoid pulling on the wire itself during removal. Confirm the vehicle application by year before ordering: Fits 1995-2003 Hyundai Accent, N/A.
