NGK iridium plugs represent the ultimate evolution of spark plug technology and performance. The iridium center electrode is both stronger and harder than platinum. This tapered cut iridium center electrode reduces the voltage requirement for spark. This allows for a brighter, stronger spark from your existing ignition system. A platinum tipped ground electrode further contributes toward the extreme longevity of this plug. These NGK plugs will get your Genesis running smoother and free up some power through increased efficiency and increased heat resistance.
Extreme Long Life Laser Iridium Plug, 14mm Thread, 26.5mm (1.04") Reach, 5/8" (16mm) Hex Size, Gasket Seat, Resistor, Projected Tip, Solid Terminal, Iridium Tipped Fine Wire Center Electrode with Platinum Tipped Ground Electrode, .032" (0.8mm) Gap, Heat Range 6
Iridium plugs are able to use larger gap setting with less voltage. Some customers choose to regap these plugs to correct misfiring or tune for optimal spark -- do so at your own risk -- slide-type plug gapper will damage the fragile iridium tip.
