The "Inferno 2" coil was designed to be used with the Duraspark distributor to provide a reliable, yet "seat of the pants" performance up to a maximum of 10,000 rpms!. When used with the Dyna-Module, spark plug gaps can be opened up to .055". 

For street applications, a 1 ohm resistor (included) must be used. which limits maximum rpm's to 7000. The resistor is used as a precautionary measure to protect the coil and module from premature failure on long periods of running time. Even with the resistors in the system, the firepower from this kit is still much hotter than the stock Ford coils and modules.

For all out racing applications, a ½ ohm resistor will be required, which allows the system to produce an intense spark up to 10,000 rpm's. 

Price includes the "Inferno 2" coil, an ultra conductive coil wire, all necessary hardware. wiring. and easy to follow instructions.

Note: The photo below shows a conventional round style coil being used, but the wiring and installation would be the same.
