Iridium Spark Plug Product Line Details

The Autolite Iridium Spark Plug line focuses on delivering long-lasting performance and improved ignition reliability. The XP5224 model features a fine wire iridium center electrode that provides a stable spark while reducing electrode wear. This product line is designed to meet the demands of modern engines requiring precise ignition timing and efficient combustion, making it suitable for both daily driving and performance-oriented vehicles.

Technical Description and Features

The XP5224 spark plug incorporates a copper core center electrode that enhances electrical conductivity, paired with an iridium tip to resist wear and maintain spark quality over time. The ground electrode uses a taper cut design with a platinum tip, which helps improve spark exposure and combustion efficiency. The ceramic insulator provides excellent heat resistance and electrical insulation, while the resistor built into the plug reduces electromagnetic interference that can affect vehicle electronics. The flat seat and crush washer ensure a proper seal in the combustion chamber, preventing leaks and maintaining engine performance.
