What is the main benefit of the iridium alloy center electrode?

The iridium alloy center electrode has an extremely high melting point, which contributes to its durability and ability to maintain a consistently stable spark. This is important for reliable engine performance.

Does this spark plug come with hardware or seals?

This spark plug is designed with triple seals to prevent leakage. It is sold individually and does not typically include additional hardware beyond what is integrated into the plug itself.

Why is the platinum pad on the ground electrode important?

The platinum pad on the ground electrode helps ensure even wear, especially in modern distributorless ignition systems. This contributes to the overall longevity and consistent performance of the spark plug.

Product Details

The fine wire center electrode on this NGK Laser Iridium spark plug is made from an iridium alloy that has a very high melting point, making it durable and able to provide a consistently stable spark. This plug is designed as an OE replacement, meaning it's built to the same standards as the original equipment your vehicle came with. It's a solid option for many motorcycles and powersports vehicles that require a fine wire iridium plug.

NGK uses a pure alumina silicate ceramic insulator for superior strength and better heat transfer, helping to prevent overheating. The pure copper core also aids in heat removal. For improved wear in distributorless ignition systems, most Laser Iridium plugs like this one include a platinum pad on the ground electrode. The trivalent metal plating on the exterior helps resist corrosion and makes installation easier by preventing seizing.

This spark plug is sold individually, but if you need a full set, be sure to order four. It's a good choice for vehicles that originally came with fine wire iridium alloy plugs, offering both performance and longevity.
