What do the drains in the air box remove?

The drains in the air box are specifically designed to remove accumulated liquid. The primary function of these drains is to prevent water and any other liquids from accumulating within the air box, which could interfere with the performance of the engine by disrupting normal airflow or leading to potential operational issues. Keeping the air box clear of liquid is crucial for maintaining the integrity of the air intake system, ensuring that the engine receives the correct flow of air for combustion. This process helps to enhance engine efficiency and prevent damage caused by the presence of unwanted liquids.

In contrast, draining excess air, debris, or excess fuel does not align with the purpose of air box drains, as these issues are typically addressed through different systems or mechanisms within the engine structure.
