How many spark plugs are in this box?

This listing is for a single NGK Laser Iridium spark plug. If your vehicle requires multiple plugs, please order the appropriate quantity. For example, if your vehicle uses four spark plugs, you would order a quantity of four.

What makes iridium spark plugs better than platinum?

Iridium is a much harder metal than platinum and has a higher melting point. This allows for a finer wire electrode, which requires less voltage to create a spark and results in a more consistent and stable spark for improved combustion.

Does this spark plug come with anti-seize pre-applied?

While the spark plug features trivalent metal plating for superior anti-corrosion and anti-seizing properties, it is always recommended to refer to the manufacturer's installation instructions for specific application of anti-seize compound.

Product Details

When it's time to replace the spark plugs on your motorcycle or performance vehicle, NGK Laser Iridium plugs are a solid choice for getting that engine running smoothly again. These are designed to be a direct OE replacement, meaning they're built to the same standards as what came from the factory, ensuring a proper fit and function.

What sets these plugs apart is the fine wire center electrode made from an iridium alloy. This material has a very high melting point and provides a stable spark, which is crucial for today's high-tech engines. The pure alumina silicate ceramic insulator helps with heat transfer, keeping the plug at the right temperature, while the trivalent metal plating on the exterior helps prevent corrosion and seizing, making them easier to remove next time. For vehicles with distributorless ignition systems, most of these plugs also include a platinum pad on the ground electrode for even wear.

This particular plug, the CR9EIA-9, is sold individually but comes in a box of four, making it convenient for multi-cylinder applications. They are a popular choice for many Kawasaki, Suzuki, and Yamaha models, offering a good balance of performance and durability.
