Spark plug gap is a critical ignition specification that controls combustion efficiency by regulating the distance an electrical arc jumps across plug electrodes, ensuring proper flame kernel growth, fuel burn stability, and long-term engine reliability. In 15 years of dealership and independent shop work, over 70% of misfires diagnosed on OBD-II vehicles traced back to … Read more
Spark plug wires is an ignition system component that transfers high-voltage current from the ignition coil or distributor to the spark plugs by insulated conductive cores, ensuring reliable combustion, reduced misfires, and stable engine performance. In 15 years, over 70% of misfire complaints traced back to aged wires exceeding 12,000 ohms per foot. What are … Read more
