Things To Note When Replacing Spark Plugs Yourself

Because the car's fuel consumption increased, I decided to change the spark plugs. I heard from a friend that it was difficult to pull out the spark plug when changing it for the first time, so I searched for a spark plug puller. I didn't expect that it is actually not that difficult to pull out. You have to lean forward, but the result is the same: it doesn't move at all.
Therefore, if you want to change the spark plug of your car for the first time, you should prepare a long lever like me, put one end on the air filter box, and support the puller in the middle. Lift it hard, and the engine will shake a few times and it will almost come out.
The spark plug gap has reached 1.1 after more than 60,000 kilometers. After replacing it with a new one, the feeling is obviously different. The refueling is much more sensitive. The fuel consumption has to be checked and it is expected to be reduced. Therefore, I personally think it is better to replace the original spark plugs for around 50,000 yuan. suitable.
After the car's spark plug was replaced, the actual measurement showed that on the same road section, the computer's average fuel consumption showed 4.7. Therefore, timely replacement of spark plugs will help control fuel consumption.
