What It Helps Address

• Hard starting related to weak ignition transfer
• Rough idle from inconsistent spark delivery
• Voltage leakage from deteriorated boots or insulation
• Corrosion at wire terminals and connection points

Installation Notes

Route each wire to match the original layout and keep it away from exhaust heat and moving components. Apply the included dielectric grease at the boot-to-plug and boot-to-coil connection points as directed by the vehicle service procedure. Verify each lead is fully seated before starting the engine.
