NGK Iridium Spark Plug Box of 4 (DPR8EIX-9)

The fine iridium center electrode on these NGK Iridium IX spark plugs is six times harder than platinum, offering exceptional durability. These plugs are a solid option for anyone looking to upgrade from standard nickel alloy spark plugs, especially if your vehicle has been modified or sees high-performance use. The iridium alloy's high melting point makes it well-suited for today's hotter-running engines.

Beyond the durable iridium tip, these plugs feature a tapered cut ground electrode. This design helps with easier starting, smoother idling, and improved throttle response. They also come with a trivalent metal plating that helps prevent corrosion and seizing, making installation and removal a bit easier down the road. You get outstanding acceleration and better fuel efficiency with these, thanks to their ability to maintain a consistent spark.

This is a box of four spark plugs, designed to fit a wide range of motorcycles and ATVs. For example, they fit models like the Honda TRX300 FourTrax and the Yamaha YFM700 Grizzly. Always check the fitment guide to confirm compatibility with your specific vehicle.
