AIR FILTER

The WIX 49478 is a heavy-duty panel air filter designed for diesel engines in Freightliner trucks such as the Cascadia, Coronado, and 122SD. It uses cellulose filtration media to trap dirt, dust, and debris, protecting the engine from premature wear and ensuring proper airflow. Replacing a clogged filter at recommended service intervals helps maintain fuel efficiency and engine performance. The filter features durable construction with pleat stabilization and corrosion-resistant components to meet OEM standards.
