This 6-piece set uses NGK’s V-groove electrode geometry and a high-performance nickel electrode to promote consistent spark formation in older distributor-ignition and waste-spark systems. The plugs are built with precision laser-welded construction to resist electrode wear and ensure dimensional accuracy at installation.\u003c\/p\u003e\n\n\u003ch3\u003eHow do these NGK V-Power plugs affect engine starting and idle?\u003c\/h3\u003e\n\u003cp\u003eUpgrading to the correct NGK V-Power plug helps the air–fuel mixture ignite consistently on each cylinder, which improves cold starts and steadies idle. For older 4.0L six-cylinder engines, proper spark energy reduces misfires and smooths low-rpm behavior without altering tuning or fuel delivery.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eDesigned for older combustion chambers and ignition systems\u003c\/li\u003e\n  \u003cli\u003eV-groove electrode promotes stable spark kernel formation\u003c\/li\u003e\n  \u003cli\u003eHigh-performance nickel electrode balances life and cost\u003c\/li\u003e\n  \u003cli\u003eSold as a 6-pack to replace all cylinders at once\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill these plugs fit my 1991–1998 Jeep Cherokee 4.0L L6?\u003c\/h3\u003e\n\u003cp\u003eYes—this set is specified to match the spark plug reach, thread size and heat range required by the 4.0L inline-six used in Cherokee models from 1991 through 1998.
