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

The kit includes the S&S HI-4N ignition module, an S&S single-fire ignition coil and 8.5 mm double silicone spark plug leads with black ferro-spiral core. It offers switchable single/multi-fire, race/street mode, rev limiter and kick/electric start mode, with no PC required. This HI-4N module was previously manufactured by Crane and now by S&S. Nothing has changed except the name. Same excellent technology, same reliable electronics. The HI-4N offers more options than the famous HI-4, with even greater reliability. The HI-4N comes with switchable single/dual fire (with integrated single/multi-fire, race/street mode, rev limiter and kick/electric start mode). Easy initial static setup with integrated LED timing light. The sensor housing contains fully encapsulated electronics to resist vibration, moisture and dust, and mounts directly onto the metal housing, which acts as a heat sink to prevent overheating. Easy adjustment with 4 rotary switches offering perfect precision.
Note: Compatible with 2-3 Ohm coils. It is recommended to use ignition modules and coils from the same manufacturer. Mixing different brands can cause premature failure.
Note: The ignition rotor (OEM 32402-83) and mounting bolt (2611B) must be ordered separately or reused. The rotor and bolt kit is available as 902268 (S&S) or 920402 (import).
Note: The module may not fit 00-03 XL models due to the slightly smaller diameter ignition cone used on 00-03 Sportsters.
Note: The difference between single and dual fire explained:
- Double fire - This is how 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 subtract horsepower.
- Single fire - This is how stock 00-up Twin Cam engines operate. Two separate coils fire the spark plugs independently and only the spark plug of the cylinder on the compression stroke is fired. These engines are said to vibrate less and can improve power. The effects become more noticeable with more aggressive camshafts and higher RPMs.
