S&S HI-4N ignition module coil and spark plug wire kit

Kit includes S&S HI-4N ignition module, S&S single fire coil and black 8.5mm double silicone ferro-spiral core spark plug wires. Offers switchable multi/single spark, race/street mode, RPM limiter and a kick/electric start mode, no PC required. This HI-4N module used to be made by Crane, now by S&S. Nothing changed but the name. Same great technique, same dependable electronics. The HI-4N offers more options than the famous HI-4, with even better reliability. The HI-4N comes with switchable single/dual fire (with built-in, multi/single spark, race/street mode, RPM limiter and a kick/electric start mode). Easy initial static set-up with built-in LED timing light. The sensor housing contains fully encapsulated electronics to resist vibration, moisture and dust, and are mounted directly to the metal housing which serves as a heat-sink to prevent overheating. Easy adjustment with 4 rotary switches that offer perfect precision. Note: Compatible with 2-3 Ohm coils. It is recommended to use ignition modules & coils of the same manufacturer. Intermixing different brands may cause premature failure. Note: The ignition rotor (OEM 32402-83) and mount bolt (2611B) must be ordered separately or re-used. Rotor & bolt kit is available as 902268 (S&S) or 920402 (import). Note: Module may not fit 00-03 XL models due to the slightly smaller diameter of the ignition cone used on 00-03 Sportsters. Note: The difference between single dual fire explained: – Dual fire – This is the way the earlier, pre-Twin Cam, engines work. A single coil is used and both spark plugs fire simultaneously. This is the simplest system. The ‘wasted’ spark is sometimes said to be horsepower robbing. – Single Fire – This is the way the stock 00-up Twin Cam engines work. Two separate coils will fire the spark plugs independently and only the spark plug of the cylinder that is on compression stroke will be fired. It is said that these engines vibrate less and can improve power. The effects will become more pronounced with hotter cams and higher RPM.

For 70-99 Big Twin (excl. Twin Cam) and 71-01 Sportster (excl. 1200S)
