Key Benefits:

* Exceptional Durability & Longevity: Specifically designed to offer a significantly longer service life compared to conventional spark plugs, reducing maintenance frequency and costs.
* Enhanced Ignitability & Performance: The fine-wire iridium tip ensures a highly focused spark, requiring lower voltage to fire. This translates to quicker starts, sharper throttle response, and more stable combustion across all RPM ranges.
* Improved Fuel Efficiency: By optimizing the combustion process, this spark plug helps your engine burn fuel more completely, potentially leading to noticeable improvements in fuel economy and a reduction in harmful emissions.
* Superior Anti-Fouling: The advanced design and high-grade materials provide excellent resistance to carbon buildup, ensuring reliable performance even during long periods of idling or trolling.
* Outstanding Corrosion Resistance: Featuring trivalent metal plating, the plug offers superior anti-corrosion and anti-seizing properties, which is essential for withstanding the moisture and salt present in a marine environment.

Main Features:

The NGK 6748 Laser Iridium Spark Plug is a testament to precision manufacturing and cutting-edge design. Its construction integrates several key features that work in concert to deliver its class-leading performance.

Original equipment on many late model applications.

Iridium at the fine-wire center electrode and platinum at the ground electrode provides maximum durability and performance.

The platinum at the ground electrode adds extra protection against plug wear and gap erosion.

Sold in standard pack only.
* Laser-Welded Iridium Center Electrode Tip: Ensures high durability and a consistently stable spark for precise ignition.
* Platinum Disc Welded to Ground Electrode: Works in conjunction with the iridium tip to provide long life and resist gap erosion.
* Long Insulator Nose: Prevents fouling and misfiring.
* Corrugated Ribs on Insulator: Prevents spark flashover, ensuring the ignition energy is directed to the electrode tip.
* Triple Gasket Seal: Eliminates combustion gas leakage for sustained engine compression and performance.
