Iridium plugs last longer and keep a strong spark as they wear; standard plugs are a cost-effective OEM-style replacement. Plug wires should be replaced when they show cracks, burns or high resistance. Always route wires exactly as the originals were routed, away from exhaust heat.\u003c\/p\u003e\n\u003ch2\u003eTroubleshooting Signs It’s Time to Replace\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eHard starting, especially when the engine is warm\u003c\/li\u003e\n\u003cli\u003eMisfires, popping or a rough idle\u003c\/li\u003e\n\u003cli\u003eHesitation or stumbling under acceleration\u003c\/li\u003e\n\u003cli\u003eWorse fuel economy than usual\u003c\/li\u003e\n\u003cli\u003eCracked, burned or corroded plug boots and wires\u003c\/li\u003e\n\u003cli\u003ePlugs with heavy carbon, oil fouling or worn electrodes\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eIf you notice any of these, inspect the system and replace worn parts before your next ride.\u003c\/p\u003e\n\u003ch3\u003eCare and Maintenance\u003c\/h3\u003e\u003cp\u003eInspect the part at every service, keep it clean, and replace it if it shows wear or damage.\u003c\/p\u003e\n\u003ch2\u003ePair It With\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003ca href=\"https:\/\/buywitchdoctors.com\/products\/ignition-coil-black-by-drag-specialties-2102-0330\" title=\"Drag Specialties Ignition Coil Black 2102-0330\"\u003eDrag Specialties Ignition Coil Black\u003c\/a\u003e (2102-0330)\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"https:\/\/buywitchdoctors.com\/products\/spark-plug-wires-black-by-drag-specialties-2104-0295\" title=\"Drag Specialties Spark Plug Wires Black 2008-20017 Victory 2104-0295\"\u003eDrag Specialties Spark Plug Wires Black 2008-20017 Victory\u003c\/a\u003e (2104-0295)\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eShop more \u003ca href=\"https:\/\/buywitchdoctors.com\/collections\/victory-indian-motorcycle-ignition\" title=\"Victory \u0026amp; Indian Motorcycle Stators, Regulators, Starters\"\u003eignition and charging parts\u003c\/a\u003e, \u003ca href=\"https:\/\/buywitchdoctors.com\/collections\/msd-coils-spark-plug-wires-for-victory-motorcycles\" title=\"MSD Powersports Ignition Components\"\u003eMSD ignition components\u003c\/a\u003e, and \u003ca href=\"https:\/\/buywitchdoctors.com\/collections\/motorcycle-batteries-electrical\" title=\"Victory \u0026amp; Indian Motorcycle Batteries, Charge Ports \u0026amp; Cables\"\u003ebatteries and electrical\u003c\/a\u003e.\u003c\/p\u003e\n\u003ch2\u003eHelpful Guides From the Witchdoctors Blog\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/buywitchdoctors.com\/blogs\/news\/how-to-determine-or-diagnose-if-you-have-a-bad-fuel-pump-or-fuel-pressure-regulator-on-a-victory-or-indian-motorcycle\" title=\"Is Your Victory or Indian Motorcycle Hard Starting?\"\u003eIs Your Victory or Indian Motorcycle Hard Starting?\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/buywitchdoctors.com\/blogs\/news\/spring-tune-up-for-your-victory-or-indian-motorcycle-get-ready-to-ride\" title=\"Spring Tune-Up for Your Victory or Indian Motorcycle: Get Ready to Ride!\"\u003eSpring Tune-Up for Your Victory or Indian Motorcycle: Get Ready to Ride!\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/buywitchdoctors.com\/blogs\/news\/victory-indian-motorcycle-spring-maintenance-checklist\" title=\"Victory \u0026amp; Indian Motorcycle Maintenance Checklist\"\u003eVictory \u0026amp; Indian Motorcycle Maintenance Checklist\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\u003ch3\u003eIs it a direct fit?\u003c\/h3\u003e\u003cp\u003eYes, for the models listed.
