The automobile air inlet hose is broken. Is it necessary to return it?

Hello! Whether the air inlet hose needs to be replaced depends on whether it is in front of or behind the air cleaner. If it is in front of the air filter, it can be considered, but if it is behind the air filter, it must be replaced. Because if the hose is in front of the air cleaner, no matter how big the dust and dirt are, it will be filtered out by the air cleaner. If the hose is behind the air filter, the dust and dirt in the air will directly enter the engine without filtration, which will accelerate the wear of the engine, so it must be replaced.
