Fresh-air Duct

Purpose, function

• Brings in fresh air from outside the engine compartment.

• Increases air density by taking fresh air, which is cooler than the engine compartment, to enhance the charging efficiency, ensuring combustion stability.

Construction

• The fresh-air duct is installed to the air cleaner.
