NGK Laser Iridium Spark Plug Box of 4 (KR8BI)

NGK is well-known for making reliable ignition components, and their Laser Iridium spark plugs are a prime example of that. These are designed to be a direct OE replacement, meaning they meet the same standards as the plugs that came on your vehicle from the factory. If you're looking to replace worn-out spark plugs on a range of vehicles, including many Can-Am Spyder models and the Lamborghini Murcielago, these are a solid option.

What sets these apart is the iridium-tipped center electrode, which is significantly harder than platinum and offers a more stable spark. This helps ensure consistent combustion and can lead to improved performance and fuel efficiency over time. The pure alumina ceramic insulator helps with heat transfer, keeping the plug from overheating, while the copper core also aids in heat removal. Plus, the trivalent metal plating on the exterior helps prevent corrosion and makes them easier to remove down the road.

This set comes with four spark plugs, enough for most four-cylinder engines or for vehicles that use two spark plugs per cylinder. They feature a fine wire design for durability and a platinum pad on the ground electrode for even wear, especially in modern distributorless ignition systems.
