Our popular standard 12V/3.0 Ohm Coil puts out 28K volts for a little more "fire" in the ignition system over a stock OEM Coil. This coil is used in all of our 12V conversion kits, and is a nice addition to our kits. Can be used with stock points/condenser or can be used with Pertronix E.I.'s. Also check out our even hotter Coil as an option. 40,000 volts of power! Our P/N- 1510-10.
