Mini single fire ignition coil. 12v, 3 ohm. Black

Black. Primary resistance 3.0 Ohm, secondary resistance 15,000 Ohm. Primary inductance 16 MHY, secondary inductance 42 HY, capable of generating +40,000V output on each side. Brass terminals for primary and high voltage. The housing fins facilitate additional core cooling.
Note: Difference between Dual and Single Fire ignition:
- Dual Fire - This is how earlier, pre-Twin Cam engines operate. A single coil is used and both spark plugs fire simultaneously. This is the simplest system. The "wasted" spark is said to slightly reduce power.
- Single Fire - This is the operating system of stock Twin Cam engines (00-up models). Two independent coils fire the spark plugs individually, with only the spark plug of the cylinder on the compression stroke being activated. These engines are said to vibrate less and can improve power. The effects will be more noticeable with more aggressive camshafts and at higher RPMs.
