About the Laser Iridium High Ignitability Spark Plug Line

The NGK Laser Iridium High Ignitability Spark Plug line is designed to provide improved ignition efficiency and durability through the use of iridium-tipped center electrodes and a dual fine ground electrode design. This combination enhances spark performance and fuel combustion, which can contribute to smoother engine operation and better fuel economy. The 94697 spark plug is part of this line, optimized for secondary ignition systems in compatible Lexus and Toyota models.

Technical Details and Performance Features

This spark plug features a copper core center electrode with an iridium tip, which offers a balance of excellent electrical conductivity and wear resistance. The dual fine ground electrode design improves ignitability by providing a more precise spark gap, while the nickel ground electrode core ensures durability. The pre-gap size of 0.032 inches is factory set to optimize ignition timing and combustion efficiency. The flat seat type and 14 mm thread diameter with a 26.5 mm reach ensure proper fitment and sealing in the combustion chamber.
