What is the effect of air leakage in Lefeng air filter hose?

The air leakage of Lefeng air filter hose has an impact on the engine, which is easy to be contaminated with impurities, blocking the intake passage and affecting the engine work.

The filter is installed in an empty filter housing. The air cleaner housing is the housing and carrier of the air cleaner. If it is broken, the impact is that some air directly passes through the throttle or idle valve without filtering and enters the mixed combustion of engine and gasoline. Therefore, the hole in the air cleaner housing has no effect on idle speed. Even if the air filter is not installed, it is still a fairly large hole, which has no effect on the idle speed, because it will not increase the air intake of the engine, and the air intake is controlled by the throttle or idle valve. Unless there is air that is not controlled by the engine computer, throttle or idle valve, the idle speed will be unstable. If the pipe behind the throttle leaks.
