Details on the 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 and platinum electrode materials. This product line is designed to provide stable spark generation and longer service life compared to conventional spark plugs. The 1402 part number exemplifies these qualities with its combination of iridium center electrode and square platinum ground electrode tip, tailored for vehicles like the Acura RDX.

Technical Description and Specifications

This NGK spark plug features a copper core center electrode with an iridium tip, which enhances electrical conductivity and wear resistance. The ground electrode uses a nickel core with a square platinum tip, contributing to high ignitability and consistent spark performance. The plug’s resistance is rated at 5000 ohms, helping to reduce electrical noise and improve ignition system reliability. With a pre-gap size of 0.032 inches and a flat seat design, it ensures proper fit and optimal combustion chamber sealing. The 26.5 mm reach and 12 mm thread diameter are compatible with the Acura RDX engine specifications.

Applications and Problem Solving

• Compatible with Acura RDX models requiring precise ignition components
• Addresses misfires caused by worn or inefficient spark plugs
• Improves cold start performance and throttle response
• Reduces fouling and electrode wear in high-heat conditions
• Supports stable engine operation under varied driving conditions

Installation Notes and Tips

When installing the NGK Laser Iridium High Ignitability Spark Plug 1402, ensure the spark plug gap is set to the specified 0.032 inches if adjustment is necessary. Use a torque wrench to tighten the plug to the manufacturer’s recommended torque to avoid damage to the threads or improper sealing. The 5/8 inch hex size allows for standard spark plug socket compatibility. Confirm compatibility with the Acura RDX engine before installation.
