Spark Plugs/Ignitions Systems05Electrical & IgnitionACCEL PLATINUM SPARK PLUGSOur Accel platinum tipped performance spark plugs are manufacturedwith state-of-the-art components in the good old U.S.of A.The platinumtip provides longer life and durability.Because platinum is more durable,it's able to maintain a precise gap much longer than ordinary sparkplugs. By maintaining that gap with platinum, required voltage remainsconstant,which results in fewer miss-fires.This translates into smootheridling, quicker acceleration, and better fuel economy over the life of theplug.The knurled side wire is produced from the best high chromiumnickelalloy for greater durability and allows for greater spark withreduced voltage while the pure copper core center wire helps todecrease fouling. For performance at its best, use these Platinum sparkplugs.

Other features are: Five-rib "alumina"powder insulator to prevent flash-over and misfire, copper glass innerseal and electric heat seal to prevent combustion leakage, fusedcopper/nickel center electrode providing super conductivity and a wideheat range.pack HeatZPN Model Year Accel qty. rangenr.231717 883 Sportster 1986-up 2418 2 standard231722 900 Sportster 1957-1971 2402A 2 hot231722 1000 Sportster 1972-1978 2402A 2 hot231717 1100 Sportster 1986-1987 2418 2 standard231711 1200 Big Twin 1948-1974 2401 2 cold231722 1200 Big Twin 1948-1974 2402A 2 standard231715 1200 Shovelhead 1975-early 1978 2403A 2 standard231714 1200 Shovelhead late 1978-1980 2410A 2 standard231717 1200 Sportster 1988-up 2418 2 standard231715 1340 Shovelhead late 1978-1979 2403A 2 cold231724 1340 Shovelhead late 1978-1979 2403 2 standard231714 1340 Shovelhead 1980-1981 2410A 2 standard231724 1340 Shovelhead 1980-1981 2403 2 cold231714 1340 Evolution 1984-up 2410A 2 standard231717 1450 Twin Cam 1999-2006 2418 2 standard231717 1550 Twin Cam 2007-up 2418 2 standardTABEL CROSS-REFERENCEOEM Zodiac Accel Zodiac Accel Zodiac Nology Genuinepart. no. standard part. no.
