NGK Single Iridium Spark Plug Box of 4 (CR7HIX)

The fine iridium center electrode on these NGK Iridium IX spark plugs is a key detail, offering six times the durability of platinum. This means you get a consistent, strong spark that helps with starting, idling, and throttle response across a wide range of ATVs and motorcycles. They're a solid upgrade over standard nickel alloy plugs, especially if your engine runs hotter or you're looking for improved performance.

NGK uses a trivalent metal plating on the exterior of the plug, which helps prevent corrosion and makes them easier to remove down the road. The iridium alloy itself has a very high melting point, making it well-suited for today's engines that often run hotter. This plug is designed for durability and improved fuel efficiency, making it a popular choice for many applications.

This particular plug, the CR7HIX, is sold individually but comes in a box of four if you need a full set for your vehicle. It's a good option for modified or high-performance applications, or simply as a way to get a more reliable spark from your stock engine.
