Hi Michael, I'm glad to assist you. The output voltage of an ignition coil in most modern vehicles typically ranges from 30,000 to 50,000 volts, with high-performance coils capable of producing even higher voltages. This high voltage is crucial for generating a strong spark to ignite the air-fuel mixture in the combustion chamber, ensuring efficient engine operation. This set is currently out of stock. For us to check carefully and be accurate on the part you need, please provide the complete details of your vehicle (year, make, model, submodel, 2WD/4WD, and engine size).
