Everyone loves better performance, right? Well how about better performance because of a quicker throttle response, improved efficiency and reduced emissions? This what you get with this Accel SuperStock Spiral Wire Set. Designed to upgrade the factory ignition system, it offers a staggering 500 Ohms per foot of resistance so more ignition energy can reach the spark plug. This produces a hotter and longer lasting spark flame. The SuperStock Wire Set also features stainless steel plug terminals and fiberglass braiding for greater pull strength and terminal retention, while its double silicone construction is rated to 550 degrees Fahrenheit. Installation is a snap as well and does not require any cutting. Will fit 1999 Wranglers with distributor. Will not fit 2000 and newer Wranglers.
