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 a combination of iridium-tipped center electrodes and a dual fine ground electrode design. This configuration reduces voltage requirements for ignition, promoting smoother starts and better fuel combustion. The 93759 part number exemplifies these features, making it suitable for vehicles requiring precise ignition components.

Technical Description and Compatibility

This spark plug features a copper core center electrode with an iridium tip, which enhances electrical conductivity and electrode longevity. The single nickel ground electrode with a dual fine tip design improves ignitability by providing a consistent spark. The flat seat and 26.5 mm reach ensure proper fitment in compatible engines. The non-removable nut terminal type offers a secure electrical connection, reducing the risk of loosening during operation.

Compatible with Nissan models such as Armada, Frontier, Pathfinder, TITAN, Xterra, and NV series (NV1500, NV2500, NV3500), as well as Infiniti QX56 and Suzuki Equator, this spark plug meets the ignition requirements for these vehicles.

Common Applications and Issues Addressed

• Improves ignition reliability in Nissan Armada and Frontier engines
• Reduces misfires and rough idling in Infiniti QX56 and Nissan TITAN
• Enhances fuel efficiency and combustion stability in Suzuki Equator
• Supports consistent engine starts in Nissan Pathfinder and NV series vans
• Helps maintain optimal engine performance under varied driving conditions

Installation Notes and Tips

• Verify compatibility with vehicle make and model before installation
• Use a 5/8 inch socket wrench for proper tightening of the spark plug
• Ensure the pre-gap of 0.044 inches is maintained or adjusted as needed
• Apply anti-seize compound sparingly on threads if recommended by vehicle manufacturer
• Torque to manufacturer specifications to avoid damage to the spark plug or cylinder head
