NGK Laser Iridium Spark Plug Box of 4 (KR8AI)

You're getting a box of four NGK Laser Iridium spark plugs, part number KR8AI. These are designed as direct OE replacements, meaning they're built to the same standards as what came on your vehicle from the factory. They're a solid choice for many ATVs, snowmobiles, and motorcycles, offering a good balance of performance and how long they last.

The center electrode uses an iridium alloy, which is much harder than platinum and helps ensure a consistent, stable spark over a long time. This is important for reliable starting and smooth running. The pure alumina ceramic insulator helps manage heat, and the trivalent metal plating on the outside helps prevent corrosion and makes them easier to remove later on. Most of these also have a platinum pad on the ground electrode to help them wear evenly, especially in modern ignition systems.

Because these are sold as a box of four, you'll want to order four plugs if you're replacing them on a four-cylinder engine or any vehicle that uses four plugs. Always check your vehicle's service manual to confirm the correct plug and the number of plugs needed for your specific application.
