Text excerpt from the catalog:
Eco Line High Power Dual Fire ignition coils in a compact housing that bolts straight into the stock location. These ignition coils are economically priced but offer 30.000 Volts that typically increases peak spark voltage by 20% or more. Improves starting, eliminates high speed miss fires and increases mileage and overall performance. Note: Dual Fire ignitions have one set of breaker points or one pick up. Single Fire ignitions have two set of breaker points or two pick ups. A Dual Fire coil will not work with a Single Fire ignition and a Single Fire coil will not work with a Dual Fire ignition.
