How Often Do The spark plug china Need To Be Changed?
The spark plug is the heart of a car engine. In order to output power from the car engine, the spark must ignite the fuel-air mixture in the car engine cylinder, so that there will be power output. The bigger the spark, the more stable the fuel-air mixture is and the easier it is to ignite. After the spark plug is used for a long time, it is difficult to generate sparks and needs to be replaced in time. Generally speaking, different grades of spark plugs have different replacement times. How Often Do The Spark Plugs Need To Be Changed?

1. The low-end car spark plug should be replaced once every 20,000 kilometers.

The low-end spark plugs are all nickel alloys. Due to its low price, this metal is generally used on low-end spark plugs, and its service life is generally designed to be 20,000 kilometers. Many car owners run out of it in about a year. Although low-end spark plugs are cheap, it's better not to choose low-end spark plugs to be on the safe side.

2. The mid-level car plug is replaced once every 60,000 kilometers.

Mid-level spark plugs last longer. These spark plugs are generally made by platinum, which is more expensive. Moreover, the possibility of ablation of platinum spark plugs is very small, and there are usually deposits, which is why platinum spark plugs can run 60,000 kilometers. Generally speaking, it is recommended to buy platinum spark plugs because they are economical and cost-effective.

3. High-end spark plugs are replaced once every 100,000 kilometers.
There is also one of the most expensive spark plugs, which are high-end spark plugs made of iridium. Iridium is a very corrosion-resistant and wear-resistant material, so iridium are chosen to make high-end spark plugs, but iridium spark plugs are expensive and are basically only used in large-displacement models, so not many people use iridium spark plugs.


Although it is said that replacing the spark plugs can save fuel and increase power, the improvement is not much. It is estimated that 1,000 liters can save about 1 liter. After all, the main function of spark plugs is to ignite, and many car engines do not match high-end spark plugs. Be sure to keep this in mind when replacing spark plugs. It is best to replace the spark plugs of the same grade as before, so that the performance is the best.
