Dtomi Diesel Fuel & Engine Oil Filter Set for Freightliner Cascadia DD13/DD15/DD16 — PF9908 & P551005 Compatible, Heavy-Duty

Dtomi diesel fuel filter and engine oil filter set replaces common OEM part numbers for Freightliner Cascadia DD13/DD15/DD16 engines to restore clean fuel and oil flow quickly and reliably.

This two-piece filtration kit bundles a fuel filter (PF9908 compatible) and an oil filter (P551005 compatible) designed for heavy-duty use on most Freightliner Cascadia trucks with DD13, DD15, or DD16 engines. Each unit is new, factory-tested, and manufactured to deliver high flow with effective particle capture and durable service life. The set ships complete and is intended as a direct-replacement option for many OEM references—check the listed part numbers against your vehicle before ordering.

How do these filters protect my Freightliner engine?

Clean fuel and oil reduce wear and help maintain engine efficiency. The fuel filter traps particulate contaminants before they reach injectors, while the oil filter captures debris and combustion byproducts circulating in the lubrication system.

• Fuel filtration targets particles 10 microns and larger for injector protection.
• Oil filtration removes metal shavings, soot, and sludge to protect bearings and rings.
• High dirt-holding capacity extends service intervals when used with proper maintenance.

Will this kit fit my vehicle and replace OEM parts?

The set is made to be compatible with many OEM part numbers and Freightliner Cascadia models. It lists numerous replacement references for both the fuel and oil filters, but fitment depends on your engine variant and year—verify compatibility with your existing part numbers.

• Fuel filter replaces PF9908 and a range of A47x/PF/KX/FF series numbers.
• Oil filter replaces P551005 and several LF, A47x, and E5xx references.
• Designed primarily for most DD13, DD15, and DD16 engine installations.

How easy is installation and what performance can I expect?

Both filters install using standard service procedures for heavy-duty trucks and are intended as direct-replacement components for straightforward swap-outs. They are engineered to maintain proper flow rates while providing effective contamination capture so your engine continues operating smoothly between scheduled services.

• 100% new, pre-tested parts for simple replacement during routine maintenance.
• Premium filtration media and increased filter surface area for improved dirt capacity.
• No special tools required beyond typical service equipment for fuel and oil filter changes.
