Blue Streak Ignition Coil. Single Fire, 12 V, 3 Ohm for Harley-Davidson

Smaller and lighter than the original.
Fits on original mounting bracket and brackets under original covers.
It has an output of more than 45,000 volts.
Fast rise times for easier starts and elimination of spark decay, even at high RPM.
Fully encapsulated for long life, vibration resistance and rapid heat dissipation.
More spark energy than the OEM coil.
Compatible with original and aftermarket ignitions.
Note: Difference between Single Fire and Dual Fire: - Dual Fire: This is how pre-Twin Cam engines work.
A single coil is used and both spark plugs fire simultaneously.
This is the simplest system.
It is sometimes said that "wasted" spark steals horsepower.
- Single Fire: This is how the original Twin Cam engines from 00 onwards worked.
Two separate coils will fire the spark plugs independently, and only the spark plug of the cylinder that is on the compression stroke will fire.
These engines are said to vibrate less and can improve power.
The effects will be more pronounced with hotter chambers and higher RPMs.

Fits: > 65-99 BT; 65-03XL. For models with Custom Single Fire electronic ignition carburetor (except Twin Cam and other Single Fire applications)
