Iridium Spark Plug Product Line Details

The Autolite Iridium Spark Plug line focuses on delivering long-lasting performance and improved ignition reliability. Featuring a fine wire center electrode made of iridium, these plugs provide a stable spark with reduced voltage requirements. The combination of iridium and platinum materials in the electrode tips enhances wear resistance and combustion efficiency, making the XP5701 suitable for performance-oriented applications.

Technical Description and Features

The XP5701 spark plug incorporates a copper core center electrode that ensures excellent electrical conductivity, paired with an iridium tip that withstands high temperatures and erosion. The ground electrode is constructed with a nickel core and a platinum tip, designed with a taper cut to optimize spark exposure and combustion. The ceramic insulator provides thermal insulation and durability, while the resistor type design with 4000 ohms resistance helps minimize electromagnetic interference. The flat seat and M12 - 1.25 thread size ensure compatibility with specified vehicle engines, and the included washer aids in proper sealing.
