What are the effects of a small amount of water in the car's air filter after wading?

[AliceLynn]

When a small amount of water enters the car's air filter after wading, it can block the pores of the filter paper, affecting the air intake. In severe cases, it may even cause difficulty in starting the vehicle or prevent it from starting altogether. Below are the related details: 1. Risk of breakage: Generally, the air intake of passenger cars is relatively low, meaning the vehicle's wading depth is not very deep. After wading, the first thing to check is the air filter and intake pipe to assess their dry or wet condition. If the air filter used is made of inferior semi-glued paper, the wet stiffness of the filter paper will decrease upon contact with water, making it highly susceptible to damage and breakage. There is even a risk of it being sucked into the engine. Moreover, dried filter paper tends to stick together, which can also affect the overall filtration performance and air intake. 2. Moisture entering the engine: If the engine continues to operate after the air filter has been exposed to water, there is a high possibility of moisture entering the engine. A small amount of moisture entering the engine will burn along with the gasoline, which has minimal impact on the engine.
