NGK IX Iridium Spark Plug Box of 4 (DRR8EIX)

When you're looking to get the most out of your engine, especially if it's been modified or you're aiming for peak 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 durability and ability to maintain a consistent spark. This means you can expect better acceleration, improved fuel efficiency, and a longer lifespan from your plugs compared to standard options.

The iridium alloy used in these plugs has a very high melting point, making it well-suited for today's hotter-running engines. You'll notice a difference in how smoothly your engine starts, idles, and responds when you hit the gas, thanks to the tapered cut ground electrode that helps with ignitability and reduces the chance of fouling. Plus, the trivalent metal plating on the plug body helps prevent corrosion and seizing, making them easier to remove down the road. This set comes with four plugs, perfect for most 4-cylinder engines or as an upgrade for many motorcycles and ATVs.
