Enhance the performance of your computer controlled vehicle by replacing the stock coil with our high voltage Coil. The Performance Distributors coils are designed to produce an exceptional spark throughout the entire RPM range with virtually no drop off in power. Stock coils are notorious for spark falling off as the RPMs increase. The higher spark output of our coils has been dyno tested to provide more horsepower and torque over the stock coil.
The coil pack was easily installed in about 5 mins. and I ended up buying the Live wires too. So if you're gonna do this get the wires and the coil together for the best deal.

Lower Gas Milage - Lost 4-5 MPG
I've installed a K&N air intake and Cat-Back Exhaust and both improved my performance and MPG. The Screamin' Deamon performance coil lowered my MPG by 4 to 5 MPG, also installed live wires and reset my spark plug gap to .065...
There's no doubt this product improves performance in over 5 years of use. I installed live wires and auto lite plugs gapped to Davis own recomendations.. Fuel mileage normal on highway usage around 16-17 Mpg. On city driving or stop and go mileage is around 10 Mpg. Before screaming demon ,mileage never went below 15 Mpg. Any idea why, and how may I improve my mileage. Thaks, Al

Sounds like the quality of fuel you are using has less octane. I'd suggest upgrading fuel to a 91 octane.
