Details on the Laser Iridium High Ignitability Spark Plug Line

The NGK Laser Iridium High Ignitability Spark Plug line focuses on delivering improved ignition performance through the use of iridium and platinum electrode materials. This combination enhances spark efficiency and electrode longevity, which is critical for maintaining engine responsiveness and fuel efficiency in Subaru vehicles. The projected square platinum ground electrode design further supports stable ignition under various driving conditions.

Technical Description and Features

This spark plug features a copper core center electrode with an iridium tip, providing a balance of excellent conductivity and wear resistance. The ground electrode uses a nickel core with a projected square platinum tip, designed to improve ignitability and combustion stability. The 5000 ohm resistance helps minimize electromagnetic interference with vehicle electronics. With a pre-gap size of 0.044 inches and a flat seat design, the spark plug ensures proper fit and spark gap consistency for the specified Subaru models.

Applications and Problem Solving

• Compatible with Subaru Crosstrek, Forester, Impreza, Legacy, Outback, and XV Crosstrek requiring part number 93482
• Addresses misfires and rough idling caused by worn or inefficient spark plugs
• Helps improve cold start performance and throttle response
• Reduces electrical noise interference in ignition systems
• Supports consistent combustion for better fuel economy and emissions control

Installation Notes and Tips

When installing the NGK Laser Iridium High Ignitability Spark Plug 93482, ensure the spark plug gap is set to the specified pre-gap size of 0.044 inches if adjustment is necessary. Use a 14 mm socket wrench for proper torque application. The flat seat and 26.5 mm reach are designed to fit the combustion chamber precisely in compatible Subaru engines. Avoid over-tightening to prevent damage to the threads or seat.
