S&S HI-4N Multi Function Performance Ignition Kit W/Single Fire Coil

For Harley 1970-1999 Big Twin and 1971-1999 Sportster models (except Twin Cam or EFI models)

The well known Crane HI-4 ignition has been one of the most popular performance ignitions for 1970-2003 “cone” style engines for many years.

So meet the new kid in town, the Crane 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 for mode selection, advance rate, and rev limit.

These switches provide accurate and repeatable settings.
