Dynatek Dyna Miniature Coil | Dual Tower | 12V | 0.5 OHM | Black

Dynatek Dyna Miniature Coil (Single) two plugs per coil with a dual tower are designed for Twin Cam ignition systems that are designed to be used with Twin Cam style low resistance coils. It is for use in two plugged heads with a total of four spark plugs operating in a single fire. Standard Twin Cam ignition is a single fire system. Ideal for custom applications where coils need to be hidden.

The distinction between Single and Dual Fire is as follows:

Dual Fire: This refers to the operation of the older, non-Twin Cam engines. There is only one coil used, and both spark plugs burn at the same time. The most basic system is this one. It's sometimes said that the 'wasted' spark represents horsepower robbing.

Single Fire: The factory 00-up Twin Cam engines operate in a single-fire mode. The only spark plug of the cylinder that is on the compression stroke will be the only one to light thanks to two independent coils. These engines are supposed to tremble less and have more power. The effects increase in intensity with greater RPM and hotter cams.

Compatibility: 99-17 Twin Cam models in custom applications. (0.5 Ohm, carbureted or fuel injected) (NU)

Note: It is recommended to use ignition modules & coils of the same manufacturer. Intermixing different brands may cause premature failure.
