Designed specifically for the performance enthusiast, Iridium IX offers extreme ignitability, improved throttle response and superior anti corrosion. The 0.6 millimeter laser welded fine Iridium tip ensures high durability and a consistently stable spark and the tapered ground electrode minimizes electrical quenching effect. Longer insulator nose prevents carbonization, the corrugated ribs on insulator prevent flashover, and a triple gasket seal eliminates combustion gas leakage. Iridium alloy has extremely high melting point, giving it high durability to heat and electrical wear, perfect for todays high performance engines. Trivalent metal plating - superior anti-corrosion and anti-seizing properties.
I thought these spark plugs would bring my old car back to life, but they didn’t seem to make much of a difference. Maybe my engine just needs more than plugs?

Great performance boost!
After putting these NGK Iridium IX plugs in my Subaru, I noticed a significant increase in fuel efficiency. They are a bit pricier than regular plugs, but worth it for the performance gains!

Good, but had a delivery issue
The spark plugs themselves are solid, and definitely improved my car’s performance. However, the box arrived a bit late, which was frustrating. Still, I’d buy them again!

High Quality Spark Plugs!
I recently used these NGK Iridium IX spark plugs in my Honda Civic and wow, what a difference! The engine runs smoother and there's better acceleration. Great value with the box of 4 too.
