S&S HI-4N SINGLE/DUAL FIRE IGNITION

The well known S&S HI-4 ignition has been one of the most popular performance ignitions for 1970-1999 "cone" style engines for many years. Now there is the S&S HI-4N with updated features for ease of installation and set up, and for greater reliability. The bullet proof all metal housing of the HI-4N provides improved heat dissipation, and features degree and advance direction markings on the flange. A convenient cable notch in the housing makes installation easier and prevents damage to the cable. Rugged sensor/magnet housings are built into the all-metal back plate, protecting the sensors from damage during installation. The sensor housings contain advanced flux concentrators with high temperature resistant samarium/cobalt magnets for accurate and reliable triggering. The electronics are fully encapsulated to resist vibration, moisture, and dirt, and are mounted directly to the metal housing, which serves as a heat-sink. The new HI-4N ignition has four rotary switches to set advance, set rev limit and select different modes like Single or Dual fire, Multi or Single spark, Race or OE, and Electric or Kick start. These switches provide accurate and repeatable settings. Available as module only or as a complete kit with matching coils and plug wires for both Single Fire and Dual Fire applications. Fits 1970-1984 Shovelhead, 1984-1999 Evolution Big Twin and 1971-1999 Sportster except XL1200S.
