The Screamin' Demon Coils are designed to produce an exceptional spark throughout the entire RPM range with no drop in power. Stock coils are notorious for falling off as RPM goes up. The Screamin' Demon Coil dyno tests show a 3 horsepower gain at 5000 rpm over stock coils.
'98 and newer will need adapter.
The Screamin' Demon features a brass coil wire terminal that is more conductive than the stock aluminum terminal and resists corrosion. Plug gaps can be increased to .065 due to the energy of this coil.

The wider spark plug gap will allow more spark energy into the combustion chambers providing more power and improved mileage. The Screamin' Demon is too hot for stock plug wires. 8 mm spiral core wires are highly recommended. The Screamin' Demon is an externally mounted coil.The Screamin' Demon features a brass coil wire terminal that is more conductive than the stock aluminum terminal and resists corrosion.
