Custom-fit sets increase horsepower up to 5%!
Built-in capacitor delivers a shorter, hotter spark thats 300 times greater than stock Produce the most powerful spark possible; are the only wires that deliver more horsepower!
They create a super-powerful discharge that ignites every fuel mixture; rich or lean; much better than a conventional spark.
Combustion is faster and more complete, resulting in easier starts, improved acceleration, increased torque, a cleaner burn (less pollution) and no plug fouling.
And they make engine timing more precise to increase power.
Ultra-short spark duration (a million times shorter than conventional systems!) dramatically reduces spark plug wear.
Black color.
Plugs are custom tailored; connector ends are like original equipment.
