Before ordering, verify the plug part number and vehicle compatibility—engine type, drivetrain and trim level can affect the correct fit. This listing contains six spark plugs (suitable for six-cylinder applications or to keep a spare set) and represents the updated SP580X revision of the original SP580\/CYFS12YT4 design.\u003c\/p\u003e\n\n\u003ch3\u003eHow do these iridium plugs differ from standard plugs?\u003c\/h3\u003e\n\u003cp\u003eIridium is a harder, higher-melting-point metal than conventional nickel used for electrodes, enabling a finer tip that delivers a more consistent spark and improved wear resistance. That precision can help maintain reliable ignition timing and reduce electrode erosion over time without changing the engine’s factory settings.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eIridium center electrode for stable spark and extended service life\u003c\/li\u003e\n  \u003cli\u003eFine-tipped design improves ignition consistency\u003c\/li\u003e\n  \u003cli\u003eOEM specification ensures correct heat range and reach\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill these SP580X plugs fit my vehicle?\u003c\/h3\u003e\n\u003cp\u003eCompatibility depends on your vehicle’s exact engine code, model year and equipment level.
