When these signals are issued, replace the spark plugs in time

Usually, if the quality of the spark plug is relatively high, then the mileage of her replacement may be longer. The life of the specific copper core spark plug is generally 30,000 kilometers, while the life of the platinum spark plug is 80,000 kilometers. The best titanium spark plug It can reach 100,000 kilometers. However, many car owners choose copper-core spark plugs in their cars. Copper-core spark plugs can also meet our needs, and its price is relatively low, so some car owners think that such spark plugs are also good. There is no problem, so is the attachment mentioned above the correct value? Let us tell you something.
In fact, these values are just a reference value and cannot be used as a complete basis for judgment. This is mainly related to the road conditions we drive and the quality of gasoline, as well as the carbon deposits in our vehicles, etc. affect the life of the spark plug. So under what circumstances is it time to replace the spark plugs? First of all, our car feels very limp and weak when accelerating. In this case, it means that there is a problem with our spark plugs, and it must be replaced in time. If it is not replaced in time, it will cause difficulty in ignition, weak acceleration, and even cause certain damage to our engine.
The second is that the exhaust gas exceeds the standard. When the spark plug fails, the ignition system will not work normally, resulting in insufficient combustion of the mixture, and some harmful substances will be discharged without sufficient combustion. So when our exhaust gas exceeds the standard, we must check whether the spark plug needs to be replaced.
Finally, the engine has a "shocking" phenomenon. When we are driving normally in a certain speed range, the engine suddenly has a phenomenon of shaking the car. If we accelerate rapidly at this time, the power of the engine will appear moldy. When driving normally, the power of the engine is obviously insufficient. With the increase of fuel consumption, even the exhaust blast sometimes emits black smoke, which shows that the performance of our spark plugs has seriously declined, and the spark plugs must be replaced in time.
