Kit

MIA's Description

The S&S Cycle HI-4N Ignition Module Kit is an updated version of the popular Crane HI-4 ignition, designed for 1970-1999 Harley-Davidson Big Twins and 1971-1990 XL (Sportster) carbureted models. It offers more power than the stock ignition, featuring single-fire and dual-fire functions in a single module. The kit includes an all-metal housing for improved heat dissipation, a single-fire coil, and 8.8mm double silicone spark plug wires. Made in the U.S.A., it is not suitable for fuel-injected models.
