NGK IX Iridium Spark Plug Box of 4 (CR9EIX)

When you're looking to get the most out of your engine, especially if it's been modified or you're aiming for higher performance, upgrading your spark plugs is a smart move. These NGK Iridium IX spark plugs are built with a fine iridium tip, which is known for its extreme hardness and durability, lasting significantly longer than platinum. This design helps ensure a consistent and strong spark, which translates to better acceleration, smoother idling, and improved throttle response.

The iridium alloy's high melting point makes these plugs well-suited for today's hotter-running engines. Plus, they feature a trivalent metal plating that helps prevent corrosion and seizing, making installation and removal easier down the road. This set comes with four plugs, perfect for most 4-cylinder engines or applications requiring multiple plugs.

NGK is a well-known name in ignition components, and these Iridium IX plugs are a popular choice for riders and drivers who want a noticeable improvement over standard nickel alloy plugs. They are designed to provide excellent fuel efficiency and durability, making them a solid option for both performance upgrades and everyday use across a wide range of ATVs, motorcycles, and snowmobiles.
