Single Outlet Single Fire 5 Ohm Coils Black Pair

Description

NOTE: Not for Twin Cam applications.

• The “industry standard” with 35,000V spark energies second to none
• Designed to work with any Dyna ignition system
• All the features of the famous Dyna “S”, plus the special feature of firing the front and rear cylinders independent of each other, allowing a much more accurate timing of each cylinder
• The stock ignition system fires both cylinders at the same time, which works fine for the front cylinder but the rear receives the “wasted” spark when the cylinder has started its intake stroke; this can result in harder starting, increased engine vibration, backfire and raw fuel being spit back into the carb, all creating a power loss
• Dyno and top-speed testing have shown a dramatic improvement in power in all areas; bikes with hotter cams show the greatest improvement
• If you truly want to get the most out of your stock, slightly modified or all-out customized Harley-Davidson, you need a Dyna “S” single-fire ignition system
