Dynatek Dyna Single Tower Ignition Coils | 12V | 3 OHM | Green

Dynatek Dyna Single Tower Ignition Coils are designed to be utilized in unique applications where two of these coils are used for motorcycles with single-plugged heads (a total of two spark plugs) that are powered by a single fire point.

Specifications:

• Colour: Green
• 3 Ohm primary resistance

Note: For points / Dyna-S ignition, (excluding Twin Cam and other single fire applications) in custom applications. (Custom single-fire, carbureted versions)

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: 65-99 B.T. and 65-03 XL

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