When we talk about the importance of any automotive filter, it’s usually in the context of the physical protection that the filter provides, whether it be for the occupants of the vehicle or the engine. And make no mistake, the level of physical engine protection that the air filter provides is very important as the primary function of the filter, but it’s not all that matters anymore.
For an engine to run at its maximum performance with maximum efficiency, it needs to get as much oxygen into the engine as possible. Air filters for cars are designed to ensure a consistent and clean flow of air into the engine, which aids in the combustion process.
