Built to meet original-equipment specifications, they arrive pre-gapped and use nickel-plated rolled threads for corrosion resistance and easy removal. They’re engineered to work with modern gasoline engines, including many Gasoline Direct Injection (GDI) applications.\u003c\/p\u003e\n\n\u003ch3\u003eHow do these plugs improve ignition compared with standard plugs?\u003c\/h3\u003e\n\u003cp\u003eThe ultra-fine iridium firing pin lowers the voltage required to spark and focuses the energy for more consistent combustion.
