Where is the cabin air filter located in relation to the engine?

The cabin air filter is located on the passenger side, specifically to the left of the engine compartment in the Joint Light Tactical Vehicle (JLTV). This placement allows the filter to effectively clean air being drawn into the cabin from the outside before it circulates throughout the interior. Located near the engine, it benefits from the airflow created by the vehicle's operation, which helps to draw in air through the filter and into the passenger compartment.

In contrast, options suggesting locations like in front of the radiator or under the vehicle do not represent the typical installation of cabin air filters, which are specifically designed to filter air entering the cabin, rather than serving any purpose related to cooling systems or being exposed to the ground. The option indicating the driver's side is also not correct as the design of the JLTV places the cabin air filter in this designated area on the passenger side, ensuring accessibility for maintenance while effectively serving its purpose.
