M&W Pro-Drag 1 S3 CDI Ignition Box

This unit is designed to be triggered via an ECU or a Hall effect sensor, offering precise timing control for high-performance racing applications.

Yes, it features selectable power levels, allowing you to switch between 160mJ for standard operation and 250mJ for maximum race output.

No, this is a single-channel CDI intended for distributed spark setups or specific single-coil applications, rather than multi-coil direct fire configurations.

The Pro-Drag series provides significantly higher spark energy (up to 250mJ) compared to standard units, which is essential for igniting alcohol or high-boost mixtures.

Continuous operation at 250mJ generates significant heat; the selectable switch lets you lower energy to 160mJ during staging or cruising to prolong coil life.
