Increased Spark Energy! Bolt In Replacement!

Finally, a coil design that gives your ignition system real power. Real ignition power that provides more complete combustion for easier starts, better idle, snappier acceleration, and more horsepower. Real ignition power that eliminates the "6000 RPM barrier" inherent with stock systems.
We've combined low oxygen, high-conductivity, magnet wire, high-silicon core material, and non-porous epoxy impregnation to produce extremely high current and extended duration for increased spark energy. And our expert workmanship gives you the reliability needed for hard-core racing or daily street use.
