What It Helps Address

• Misfires caused by worn or damaged ignition wires
• Hard starting related to weak spark transfer
• Rough idle from inconsistent ignition output
• Voltage leakage from cracked or deteriorated wire insulation
• Intermittent engine performance issues tied to aging wire boots or terminals

Installation Notes and Tips

Confirm the engine application and wire routing before installation, then transfer each lead one at a time to preserve firing order. Inspect coil and spark plug terminals for corrosion, carbon tracking, or heat damage before connecting the new wires. The 105-degree spark plug boot design supports tighter routing in confined engine bays, and the 7mm profile helps maintain OE-style fitment on the listed Hyundai and Kia vehicles.
