Which is better, the throttle or the glass door?

Air conditioning cleaning and throttle cleaning, the other two are not necessary, except for tire repair or tire change, which requires four-wheel positioning and dynamic balance.

It is necessary to clean the air conditioner, because the car air conditioner will gather a lot of dust and dirt that we can't see with the naked eye after being used for a long time. The production of these things will not only reduce the refrigeration capacity of air conditioners, but also produce unpleasant smells in cars. And if we stay in such an environment every day, it will harm our health.

Secondly, if the air conditioner is not cleaned for a long time, it will increase fuel consumption and even affect normal use. Therefore, for everyone's health and the life of the car, everyone must develop the habit of cleaning the air conditioner.

Throttle cleaning is also necessary. The dirty throttle causes the throttle to be inflexible, and the air entering the engine carries a lot of impurities, which affects the normal combustion of gasoline and reduces the working power of the engine. In severe cases, there will be failures such as unstable idle speed, difficult start-up and power reduction.
