What It Helps Address

• Rough idle from inconsistent spark delivery
• Ignition performance loss from heat-damaged boots or terminals
• Voltage leakage from deteriorated wire insulation

Installation Notes

Match each wire to the original routing before removal to preserve firing order and clearance around hot or moving components. Inspect spark plugs, coil connections, and wire separators during installation, and apply the included dielectric grease where specified by the service procedure. Verify fitment against the vehicle year and model before installation on 2002-2005 Jeep Liberty, 2003 Jeep TJ, or 2003-2006 Jeep Wrangler.
