Dynatek Dyna Miniature Coil Set | Dual Tower | 12V | 3 OHM | Black

Dynatek Dyna Miniature Coil Set two plugs per coil with a dual tower. For use in two plugged heads with a total of four spark plugs operating in a single fire. The majority of electronic ignition systems, such as Dyna 2000i, that use dwell control have a primary resistance of 3 ohm (not for Dyna-S modules). ideal for customs applications where coils need to be hidden.

Note: For custom applications utilizing electronic ignition (excluding Twin Cam and other single fire applications). (Personalized 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, Dyna 2000i

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