M&W S4 series CDI boxes are specifically built for use with 2-stroke and high rev 4-stroke engines.
The M&W Pro-16 B is a six channel, ECU triggered, CDI ignition box. Typically used on six-cylinder, direct-fire, coil per plug engines. Includes connector plug and pin set.
The 16 B is a single box CDI. This unit will not operate a Mazda 3-rotor rotary engine. If you need a CDI for the 3-rotor engine you will need the M&W Pro-16 (no B) twin-box unit. Click HERE for more information.
