E3's new DiamondFIRE 6CDI Digital Capacitive Discharge Ignition Box features high performance digital microprocessor-controlled circuitry contained in a lightweight extruded housing. Boasting a highly efficient design, the DiamondFIRE 6CDI outperforms other 6 series boxes on the market today.

The ultra-durable DiamondFIRE 6CDI comes complete with wiring harness, hardware and mounting kits. It is compatible with even-fire 4, 6, and 8 cylinder engines and 12-volt negative ground electrical systems. It will accept input trigger signals from break points, breakerless electronic modules as well as magnetic distributor or crank trigger pickups. The box is not designed for systems with Hall Effect pickups.
