How long does it take to clean the automobile intake manifold?

The air intake system can be cleaned by purchasing a special cleaning agent, and the price ranges from tens to one hundred and two hundred yuan, but the self-cleaning effect is limited. It is recommended to go to a professional repair shop or a 4s shop for cleaning. When you go to a 4S shop for cleaning, you will generally clean the oil circuit, air intake, throttle valve, three-way catalytic converter and engine interior. The total cleaning cost is generally around 2000 yuan. If you just want to clean the air inlet and throttle separately, you can go to a professional repair shop outside, and the price is generally around 200-300 yuan.

There is no fixed period for cleaning the air intake system, which is determined by many aspects:

Personal driving habits, vehicle driving environment, EFI engine control mode, etc. If the vehicle is driving in the urban area for a long time, it is recommended to clean it every 20,000 kilometers or so. If the car often runs in an environment with poor air quality, the air intake system is more likely to get dirty, which will affect the intake of the engine for a long time and make it difficult to start the car. It should be cleaned in advance.
