The MC-3 Pro Stock Motorcycle Ignition is specifically designed for drag racing motorcycle engines equipped with dual plugs per cylinder.

Like the standard MC-3, the new MC-3 Pro Stock Ignition is a capacitive discharge multi-spark design that produces a series of extremely hot sparks.

The sparks of t he Pro Stock ked with 185mj of spark energy with 500 primary volts! The efficient CD circuits ensure that every spark, even each multiple spark, is at full power.
Below 3,000 rpm, the ignition produces a series of multiple sparks that burn in the cylinder for up to 35° of crankshaft rotation. This proven technology keeps the spark plugs clean at low rpm and improves the throttle response while reducing any chance of hesitation for off-idle acceleration.
The MC-3 Pro Stock Ignition is designed for racing applications with two spark plugs per cylinder. Since it is a race only ignition, MSD engineers included a Two Step Rev Control and Shift Interrupt feature into the ignition. The Two Step lets you set two rev limits; one to use for consistent holeshots and another for top end over rev protection. The Shift Interrupt can be connected to the air shifter so when it is activated, the ignition output is momentarily disabled to unload the transmission. This produces incredibly smooth and f ast shifts!

ring chores can be handled with MSD Hall Effect Pick-ups or the stock amplifier system. It is supplied with 11,000, 12,000 and 13,000 RPM Modules. From NHRA to Prostar, the MC-3 Pro Stock Ignition is a proven winner.

The MC-3 makes it convenient to time your engine with a built-in LED on the side. When a triggering event occurs, the LED lights up - perfect for timing your engine on the bench! It's also great for trouble-shooting ignition problems.

MSD popular 2-Step Module Selector is now built-in on the MC-3 Digital Ignition. The 2-step allows the rev control to be switched between two different RPM Modules. The low RPM slot could be used for staging at the start line, while the high RPM slot could be used for top end rpm rev limiting.
