The M548A3 engine air system allows air to enter the engine. The air cleaner cleans air that enters the engine. Air is filtered
through a reusable filter element before delivery to the engine. An air filter indicator shows when the element is clogged and
needs cleaning or replacing. After being filtered, the air moves through the turbocharger to the engine blower and into the
engine cylinders.
