What makes NGK Laser Platinum spark plugs different from standard nickel plugs?

Laser Platinum plugs feature dual platinum surfaces, one on the center electrode and one on the ground electrode. This design promotes slower wear, leading to a longer service life and more consistent performance compared to conventional nickel spark plugs.

Are these spark plugs suitable for all vehicles?

These Laser Platinum spark plugs are recommended for vehicles that originally came equipped with OE fine wire platinum alloy plugs. They are designed to meet or exceed original equipment specifications for many Aprilia and Kawasaki models.

What is the purpose of the copper core in these spark plugs?

The copper core is integrated into the spark plug's design to help with heat removal. This prevents the spark plug from overheating, which contributes to reliable starting and consistent operation.

Product Details

NGK is well-known for making reliable ignition components, and their Laser Platinum spark plugs are a prime example of that. These plugs are built to last and provide a strong spark for consistent engine performance. They are designed as direct OE replacements, meaning they are engineered to meet or exceed the original equipment specifications for a wide range of vehicles, including many Kawasaki Jet Skis like the Ultra 310 series and Aprilia Scarabeo models.

What sets these apart is the dual platinum surfaces. The platinum pad on the ground electrode, combined with the center electrode, helps ensure slow wear and a stable idle, which can lead to improved fuel efficiency and lower emissions. The pure alumina silicate ceramic insulator is strong and transfers heat well, while the copper core helps prevent overheating. Plus, the trivalent metal plating on the exterior helps resist corrosion and makes them easier to remove down the road.

This box includes four Laser Platinum spark plugs, enough for most 4-cylinder applications. They are a solid option if your vehicle originally came with fine wire platinum alloy plugs.
