Air boxes, found within the Engine Parts > Engine Miscellaneous section, are essential components of a vehicle's intake system for both passenger cars and commercial vehicles. These housings enclose the air filter and serve to provide clean, filtered air to the engine for optimal combustion. Typically located near the engine's intake manifold, air boxes protect the filter from debris, moisture, and engine heat. They are constructed from durable plastics or composites designed to withstand under-hood temperatures and vibrations. Examples in this category include the Febi FEBI30443 and Bosch 1457429942 air boxes, offering reliable protection and airflow for various engine types. Ensuring a properly sealed and functional air box is critical for maintaining engine performance and fuel efficiency.
