Part Number: 03-42776-010
The 03-42776-010 is an OEM-specification engine air filter designed for Freightliner Cascadia trucks (2018–2025 model years) equipped with Cummins ISX/X15 or Detroit Diesel DD13, DD15, and DD16 engines. It provides the primary barrier between airborne contaminants and your engine's intake system.
A restricted or clogged air filter forces the engine to work harder to draw in air, leading to incomplete combustion, increased fuel consumption, and accelerated turbocharger wear. Regular replacement at 10,000–15,000 mile intervals ensures optimal airflow, peak horsepower, and the best possible fuel economy for your Cascadia.
Direct fit for all Freightliner Cascadia trucks from 2018 through 2025. Cross-references to Donaldson P628541 and alternate Freightliner part number 03-42086-010.
