Details on NGK Laser Iridium High Ignitability Spark Plug Line

The Laser Iridium High Ignitability Spark Plug line by NGK focuses on delivering improved ignition efficiency through the use of iridium-tipped center electrodes and a dual fine ground electrode design. This combination reduces voltage requirements for spark generation, which can contribute to smoother engine starts and better fuel combustion. The 94167 spark plug incorporates these features to meet the ignition demands of modern engines like the Honda CR-Z.

Technical Description and Features

This spark plug features a copper core center electrode with an iridium tip, providing a durable and highly conductive ignition point. The dual fine electrode ground tip design enhances ignitability by creating a more focused spark gap. The nickel ground electrode core ensures structural integrity, while the non-removable nut terminal type offers secure electrical connection. With a pre-gap size of 0.052 inches and a flat seat type, the 94167 spark plug is optimized for consistent performance and fitment in the Honda CR-Z engine.

Applications and Common Issues Addressed

• Replacement for worn or fouled spark plugs in Honda CR-Z vehicles
• Improves ignition reliability and reduces misfires
• Helps restore engine starting performance
• Supports efficient fuel combustion and engine responsiveness
• Addresses rough idling and hesitation during acceleration

Installation Notes and Tips

When installing the NGK 94167 spark plug, ensure the spark plug gap is set to the specified pre-gap size of 0.052 inches if adjustment is necessary. Use a torque wrench to tighten the spark plug to the manufacturer’s recommended torque to avoid damage to the threads or seat. The flat seat design requires proper seating to maintain compression and prevent leaks. Always inspect the ignition system components for wear or damage during replacement.
