Cascadia filtration depends on the build
Freightliner Cascadia filtration packages vary by engine (Detroit DD13, DD15, DD16, or Cummins ISX/X15) and fuel-processor housing.
Air filtration
Common Cascadia air elements include 03-42776-010 (2018+) and AF27879 on earlier or alternate airboxes. Match the OEM air filter chart for your model year.
Fuel and water separation
Detroit-powered Cascadias may use cartridge separators (R61709), spin-on style elements (FS19915), DAVCO Fuel Pro elements (FS20083), or Detroit service kits (A4700903151 / A4720921705). Confirm the fuel processor housing before ordering.
Oil service
Gen 5 Detroit engines often use cartridge kits such as A4711800209. Confirm the engine vintage before ordering.

Frequently Asked Questions
Do all Cascadias use the same air filter?
No. Model year and airbox design matter. Confirm OEM numbers such as 03-42776-010 or AF27879 against your truck.
Which fuel filter does a DD15 Cascadia use?
It depends on the fuel processor. Common elements include FS19915, R61709, FS20083, and Detroit kits like A4720921705. Match the housing identification.
