Note: Difference between Single & Dual Fire: Dual Fire This is the way the earlier, pre Twin Cam, engines work. A single coil is used and both spark plugs fire simultaneously. This is the simplest system. The 'wasted' spark is sometimes said to be horsepower robbing. Single Fire This is the way the stock 00 up Twin Cam M8 engines work.
