Product Details

When you're looking to get the most out of your engine, especially if it's been modified or you're aiming for better performance, upgrading your spark plugs is a smart move. These NGK Iridium IX plugs are built with a fine iridium tip, which is known for its extreme hardness and high melting point, making it a durable choice for today's hotter-running engines.

The iridium fine wire center electrode is significantly more durable than platinum, and its design helps ensure a consistent spark. This translates to improved starting, smoother idling, and a more responsive throttle. Plus, the trivalent metal plating on the plug body helps resist corrosion and makes them easier to remove down the road.

These plugs are a popular choice for those looking to upgrade from standard nickel alloy plugs. They fit a range of vehicles, including models like the Mitsubishi Lancer and various Yamaha WaveRunners, offering a solid option for enhanced engine performance.
