Longer insulator nose , the corrugated ribs on insulator prevents 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 today's high-performance engines. Trivalent Metal Plating - superior anti-seizing properties. Review: Easy to Install - Great Product - These pre-gapped plugs are great for your engine. It took me 1 hour to replace all my old plugs with these new ones in a V-8 Mercedes 550 engine. EASY. The NKG plugs are running smoothly and sometimes, as with these, small things can make a big difference. I had previously installed Bosch, but after 50,000 miles I felt they needed to be changed because I was seeing degradation in my fuel mileage. I will come back and update this review in 5,000 miles to tell you if and when my mileage has improved. I can already see a upgrade in engine performance just going about 10 miles. Review: Great Plug! - Got 8 of these plugs for my 2008 Mercedes S550 4Matic. I noticed an increase in acceleration immediately. I've only had them for a week now, so I can't comment on mileage, value, or longevity. But, they were easy to install. I found the torque settings on the NGK website. You probably won't need anti-seize on the plugs, as they are designed to be used without it. Keep in mind that if you do use anti-seize, that your torque settings could change. Would buy this brand again. ## Features - Designed specifically for the performance enthusiast, Iridium IX offers extreme ignitability, improved throttle response - The 0.6mm 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, the corrugated ribs on insulator prevents flashover, and a triple gasket seal eliminates combustion gas leakage.

They aren't going anywhere **Q: Are these plugs pre gaped?** A: You must always check the gap on spark plug replacements against recommended gap for that specific plug.

It is a 5/8 deep socket. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Easy to Install - Great Product *by M***N on January 21, 2024* These pre-gapped plugs are great for your engine.
