• Misfire symptoms related to aged secondary ignition components
• Reduced throttle response from degraded spark delivery
• Fuel economy loss associated with inefficient combustion

Installation Notes and Tips

Verify thread size, seat type, heat range, and vehicle-specific gap requirements before installation. XP5224 uses a flat seat, M14 x 1.25 thread, and a non-removable nut terminal, so confirm the ignition coil or wire connection matches the terminal style. For best results, inspect the ignition system, replace plugs on a clean engine, and torque to the vehicle manufacturer specification.
