What is the main benefit of the iridium tip on these spark plugs?

The iridium tip on the center electrode is extremely hard and has a high melting point. This provides exceptional durability and helps maintain a consistent, stable spark over a longer period compared to standard platinum plugs.

Does this box include everything needed to replace the spark plugs on my vehicle?

This product includes a box of four NGK Laser Iridium spark plugs. You will need to have the appropriate tools to remove the old spark plugs and install the new ones.

What does the trivalent metal plating do?

The trivalent metal plating on the spark plug body helps to resist corrosion and prevent seizing. This makes them easier to remove in the future and ensures a solid connection.

Product Details

This product includes a box of four NGK Laser Iridium spark plugs, part number 93819. These are designed as direct OE replacements, meaning they match the original equipment specifications for performance and longevity. They fit a wide range of Ski-Doo snowmobiles, including models like the Ski-Doo MX Z TNT E-TEC 850 and Ski-Doo Summit SP E-TEC 850.

The center electrode on these plugs has an iridium tip, which is significantly harder than platinum and helps maintain a consistent spark over time. This advanced material also has a very high melting point, making it well-suited for modern, high-performance engines. For vehicles with distributorless ignition systems, the ground electrode includes a platinum pad to ensure even wear. The pure alumina ceramic insulator offers excellent strength and heat transfer, while the trivalent metal plating helps prevent corrosion and seizing.

NGK also incorporates a copper core to help dissipate heat away from the plug, preventing overheating. Triple seals are used to prevent any gas leakage. These features work together to provide reliable starts and durable performance.
