    The ignition system is designed to create a spark that will ignite the fuel/air mixture in the engine's cylinder. It must create a spark strong enough to burn the air/fuel mixture for easy engine starting and optimum fuel mileage as well as control the timing of the spark so it occurs at the exact right time. The performance ignition system creates a more powerful spark which ensures complete combustion, thus boosting the engine's horsepower. Upgrade the ignition system of your vehicle to get full combustion and maximum horsepower from your Cadillac STS.
