Important to know

The Intelligent Spark Technology Ignition Module requires an installation kit (sold separately). An optional high-output, single-fire coil (3 ohm per coil) designed for the S&S Variable Fuel Injection System is also available separately.

This sensor is not intended for fuel-injected models. It is not recommended for kick-start applications unless a cam position sensor is used. Engines using crankshaft position sensors will be difficult to kick start.

S&S IST ignition modules manufactured after 10-1-03 (serial number begins with "E" or higher letter) already contain software to support the Guardian Diagnostic System and will work in all applications except 2004-05. Modules manufactured after 10-1-05 (serial number begins with "G" or higher letter) are compatible with 04-05 models in addition to the other specified applications.
