【Long Service Life】Iridium Spark Plugs are engineered for original equipment and replacement applications. Every component either matches or improves on the OE design to ensure fast and easy installation with superior performance and reliability and provide long service life.
【Replacement spark plugs】Whether the spark plug needs to be replaced, take it out to check the color of the burn, the gap between the electrodes, whether the gap between the porcelain body and the metal shell is leaking, etc. If you find that the car is difficult to start in a cool state, there is obvious driving frustration, idling jitter, or engine acceleration performance declines, you should check the spark plugs in time. May be caused by aging spark plugs.
