Fitment. Don't let underperforming plugs keep your C6 Z06 from leading the pack. Only NGK Iridium IX plugs deliver the kind of performance you expect for your Z06 - and this complete set of 8 is just what you need for your LS7 engine. Note that these plugs fit 2006 C6 Z06's only.
NGK's Ultimate Design. NGK is proud to introduce the next generation in spark plug technology - the Iridium IX spark plug. Made with the finest materials and precision crafted, the design of the ultra-fine center electrode is designed exactly the right diameter to ensure both maximum durability and spark plug life while ensuring an accurate and consistent spark. It just doesn't get any more precise or reliable than this! The Iridium IX is designed to meet the expectations of those who have come to expect nothing but the best - from the company that sets the standard.
Better than Other Iridium Plugs. The NGK Iridium IX plug features NGK's fine wire design, which reduces the amount of voltage needed to create a spark. The result is less stress on your ignition system and more power. The fine wire design shows a higher resistance to fouling when compared to traditionally designed iridium plugs, and it's easier to spark in high compression, high revving engines. It's also easier to start in even the coldest climates - making this plug an exceptional choice for every Corvette application, from stock vehicles to modified racecars.
Ultra-Rare Materials. Iridium is an exceptionally rare material - more rare than platinum, and a better choice for your plugs too. It's stronger than other any other metal used in spark plugs, and it's 6 times harder than platinum, allowing NGK engineers to create this ultra-precise plug. And iridium alloy has an exceptionally high melting point - making this plug the right choice for your highly tuned, high performance engine.
OEM Quality. NGK is one of the premier manufacturers of spark plugs worldwide. All NGK plugs are made with a solid copper core, to ensure greater spark and heat transfer. Plus they use a triple gasket sealing process to eliminate the potential for combustion gas to leak back through the shell - superior to other manufacturer's one or two shell design. And their double dipped zinc chromate shell is designed for maximum corrosion and rust resistance.
