By replacing standard inductive setups with the m&w ignition pro drag 4, racers can eliminate spark blowout and maximize power delivery at the highest RPMs.

Frequently Asked Questions About M&W Ignition Pro Drag 4

What is the spark energy output of the m&w ignition pro drag 4?

The m&w ignition pro drag 4 offers switchable spark energy settings, allowing you to choose between 320mJ and 500mJ depending on your engine's specific requirements and boost levels.

Is this CDI system compatible with aftermarket ECUs?

Yes, this 4-channel CDI is designed to be triggered by most major aftermarket ECUs, including MoTeC, Haltech, FuelTech, and Link, ensuring seamless integration into your race car's electronics.

Why should I choose the m&w ignition pro drag 4 for my build?

If you are running high boost pressures or fuels like methanol, standard ignition coils often fail to fire. The m&w ignition pro drag 4 provides the massive energy needed to jump the spark gap under these extreme conditions.

Does this unit require special ignition coils?

Yes, for optimal performance and safety, you must use ignition coils specifically designed for CDI systems (low primary resistance) rather than standard inductive coils which can overheat or fail.

Can this system be used for street driving?

While it is technically possible, the Pro Drag 4 is engineered primarily for drag racing. Its high energy output accelerates electrode wear on spark plugs, making it less ideal for high-mileage street use.
