SAKES Auto Parts (Shanghai) Co., Ltd. conducts rigorous ignition coil testing to ensure the quality and reliability of its products. The testing process begins with electrical tests to measure the coil's resistance, inductance, and capacitance. These electrical measurements help to determine if the ignition coil is within the specified performance range. SAKES also performs high - voltage testing to simulate the operating conditions of the ignition coil and verify its ability to generate a strong, consistent spark. In addition to electrical tests, the brand subjects its ignition coils to environmental testing, including exposure to high and low temperatures, humidity, and vibration. This helps to ensure that the ignition coils can withstand the harsh conditions of the engine bay. SAKES also conducts long - term durability testing, running the ignition coils for extended periods to assess their lifespan and performance over time. By performing these comprehensive tests, SAKES can identify and address any potential issues before the ignition coils reach the market, ensuring that customers receive products that are reliable, efficient, and built to last.
