Double iridium spark plugs are better among all spark plugs.
Because iridium material has the characteristics of high hardness, high corrosion resistance and high melting point, the service life of spark plug is long. In addition, iridium is the most corrosion-resistant and wear-resistant precious metal, which makes the spark plug meet the needs of high-power engines. However, when selecting spark plugs, we need to pay attention to the matching relationship between spark plugs and engine models. Each series of engines has its own working temperature, and the spark plug should also have the corresponding "calorific value".
Therefore, although the performance of Copco double iridium spark plug is excellent, whether it is suitable for your vehicle needs to consider the specific situation of your vehicle.
Generally speaking, choosing a suitable spark plug is more important than choosing an expensive spark plug.
