About the NGK Laser Iridium Spark Plug Line

The Laser Iridium Spark Plug line from NGK combines iridium's high melting point with precise electrode design to provide stable ignition and long service life. This product line focuses on delivering consistent spark performance while maintaining resistance to electrode wear, making it suitable for modern engines requiring reliable secondary ignition components.

Technical Details and Performance

The NGK 3656 spark plug features a copper core center electrode that enhances electrical conductivity, paired with an iridium tip that offers superior wear resistance. The single ground electrode uses nickel core material and a standard tip design, balancing durability and performance. With a resistance rating of 5000 ohms, this spark plug helps reduce electrical noise and interference. The flat seat and precise pre-gap of .032 inches ensure proper sealing and optimal spark gap for efficient combustion in Mitsubishi Eclipse, Galant, Lancer, and Outlander models.

Applications and Problem Solving

  • Restores engine misfire issues caused by worn spark plugs
  • Improves fuel efficiency by ensuring consistent ignition
  • Reduces rough idling and hesitation during acceleration
  • Helps maintain smooth engine performance under various driving conditions
  • Prevents ignition system interference with 5000 ohm resistance

Installation Notes and Tips

When installing the NGK Laser Iridium Spark Plug 3656, ensure the spark plug gap is set to the factory specification of .032 inches if adjustment is necessary. Use a 5/8 inch socket for proper torque application and avoid over-tightening to prevent damage to the flat seat. The non-removable nut electrical terminal type requires compatible ignition connectors. Always replace spark plugs in sets to maintain balanced engine performance.

Quality Assurance and Warranty

NGK spark plugs are manufactured to meet strict quality standards, ensuring reliable performance and durability. The Laser Iridium Spark Plug 3656 undergoes rigorous testing for heat range, electrode wear, and electrical resistance. While specific warranty details may vary, NGK products typically come with manufacturer-backed quality assurance to support long-term use in Mitsubishi Eclipse, Galant, Lancer, and Outlander vehicles.
