M&W Pro Drag 4R Rotary 250mJ CDI

This high-performance unit provides selectable spark energy options, allowing you to choose between 160mJ and a massive 250mJ output.

This unit is labeled 'Pro Drag' because it is engineered specifically for high-horsepower drag racing applications requiring extreme ignition energy.

No, the Pro Drag 4R is specifically configured as a direct fire solution for Mazda two-rotor engines only.

While the Pro 14R offers 115mJ, the Pro Drag 4R more than doubles that potential with up to 250mJ to ignite fuel in extremely high-boost setups.

It utilizes a direct fire configuration, ensuring that the full 250mJ of energy is delivered directly to the specific coil without sharing channels.
