Mallory Hyfire VI-A (Hyfire 6-A) CDI Ignition Box (Capacitive Discharge Ignition), Basic Unit, Digital Ignition, 6852M is basically a device that charges your coil with 400V instead of the measly 12 it normally gets. This results in a bigger spark!
With this Capacitive Discharge (CD) system, you will have a stable, uniform spark throughout your engine's rpm range, with no high rpm drop-off like other boxes, or with a standard Kettering Ignition (Points and Condenser, or Points Replacement Device charging the coil with 12 Volts.
These Extruded Aluminum Cherry Red Anodized CDI Box is super lightweight, and gives maximum heat transfer via the finned housing.
This is the basic box, with no programmable rev limiters or 2-step devices, but the spark is identical to Mallory's other 3 CDI boxes, which have things like Adjustable Rev Limits, RPM Switches, etc etc. But the spark on all 4 Hyfire's is the SAME, the differences are all the gadgets. If you just want a big reliable spark, this box will do that without the extra cost of the other features.
This is compatible with most electronic and magnetic trigger systems.
You must have good quality plug wires, the high energy spark will push them to the limit! We have one customer that went from 2000PPM of HCs to almost 0 after installing one of these on his car. We do not promise that you'll experience similar results, but the hot spark will fire off almost anything! Obviously that guy had a very weak ignition system before installing the Hyfire-6!
During installation, we recommend you install a 20A fuse between the battery and the Hyfire unit, and wire the Hyfire Ground directly to the battery for best results.
This is the latest in Mallory's line of HyFire ignitions, the HyFire VI-A digital ignitions use the newest digital circuitry to deliver more power and quicker acceleration with less current draw. These highly efficient ignitions deliver multiple sparks per combustion event, so you get consistent, reliable performance throughout the rpm range. They have a state-of-the-art microprocessor and a durable, lightweight, extruded aluminum housing for maximum heat transfer. They're designed to work with points, OEM, or aftermarket electronic ignitions, or magnetic crank triggers. ALL CDI's exhibit the Multiple Spark event, whether it's a genuine MSD or other CDI system.
