Part Number: AF27879
The AF27879 is a primary engine air filter engineered for Freightliner heavy-duty trucks. Its panel-style design and high-density filtration media deliver superior particulate capture while maintaining the low airflow restriction that modern turbocharged diesel engines demand for optimal combustion and fuel efficiency.
Airborne contaminants are the leading cause of premature internal engine wear. Replacing the AF27879 at recommended intervals keeps combustion efficiency high, turbocharger performance consistent, and helps avoid the cascading damage that occurs when abrasive particles bypass a saturated filter element.
Direct fit for Freightliner Cascadia, Columbia, and Century trucks. Cross-references to Baldwin CA5790, WIX 49478, Donaldson P610260, and FRAM CA11249.
