Designed for dual fire applications with single or dual spark plug heads
Designed with built-in mechanical spark advance unit. Using Mallory's time tested breakerless ignition circuit, combined with modern surface mount Thermal-Clad^® construction, the kit can drive any ignition coil or combination of ignition coils with a total primary resistance of at least 2.0 OHMs
We recommend ignition coils with 2.3-3.0 OHMs for racing applications and ignition coils with 3.0-4.0 OHMs for street and highway use
Incorporates an infrared light beam and an optical interrupter to trigger the ignition. This type of trigger is extremely accurate and much more effective than hall effect (magnetic) type ignitions
Use with spiral core or carbon core suppression type spark plug wires
