Cummins 5579357 EPA13 DPF kit for ISC 8.3 and ISL 9 engines

Cummins DPF Filters

Cummins 5579357 DPF Kit

Cummins 5579357 is a diesel particulate filter (DPF) for Cummins ISC 8.3 and ISL 9 medium-duty engines, EPA13. It is emissions aftertreatment hardware, not a service element like a fuel or oil filter — and it is not interchangeable with the EPA07 or EPA10 DPF for the same engine block.

Part number: 5579357
Type: EPA13 diesel particulate filter (aftertreatment)
Engine reference: Cummins ISC 8.3 L / ISL 9 (PACCAR PX-8 / PX-9)

What 5579357 Is, and the Era That Defines It

The 5579357 DPF traps soot from the exhaust stream of a Cummins ISC 8.3 or ISL 9 engine. These medium-duty engines appear in vocational trucks, school buses, delivery vehicles and motorcoaches, and the same base design is carried under the PACCAR PX-8 and PX-9 designations.

The era is not a detail. EPA07, EPA10 and EPA13 engines carry different aftertreatment architectures and calibrations, so their DPFs are not interchangeable even where they look alike. Cummins’ own aftertreatment identification guidance treats the emissions build as part of the identity of the part, alongside the engine serial.

Emissions era

EPA13 must be confirmed before 5579357 is quoted. EPA07 and EPA10 units for the same block will not interchange.
Engine family

ISC 8.3 L and ISL 9, also sold as PACCAR PX-8 and PX-9. The model name alone does not confirm the part.
Part identity

Engine serial plus the number stamped on the removed unit. Where the records disagree, the discrepancy is the useful information.

Confirming the Part Before You Order

Work the confirmation in this order. A VIN model year alone can mislead during transition years. If the records point to a different number, the discrepancy is the useful information — it usually means a different emissions era or a supersession.

Four checks to confirm 5579357 and the method for each
Check	What to use	How to confirm
1. Engine serial (ESN)	Most reliable key	Read the engine plate and build record
2. Number off the removed DPF	Seven-digit Cummins number, including any suffix	Read the stamp on the removed unit
3. Aftertreatment serial (ATSN) or CES number	11-digit ATSN, or CES number in AxxxBxxx form	Convert through the Cummins Emissions Catalog
4. EPA emissions era	Confirm EPA13 before ordering 5579357	Check the build record

Reference numbers to review, not proof of fitment. A cross-reference gets you to a candidate filter; it does not confirm the media, the cell density or the calibration.

Genuine Original or Alternative — Declared Up Front

Cummins 5579357 genuine original or declared alternative supply — Declared on the quotation, never substituted quietly.

Declared up front, on every line.

Manufacturer-side supplier — no OEM or authorised-dealer claim

Declare it up front and we quote a genuine original reference. Where an alternative is proposed, it is labelled as one — never substituted quietly. We are a manufacturer-side supplier, not Cummins, and we make no authorised-dealer or OEM claim.

We supply legitimate replacement. We do not supply DPF-delete or emulator devices. DPF removal is illegal in most regions and voids emissions compliance.

Why the maker matters.

Cummins’ own documentation on genuine versus “will-fit” DPFs sets out why cell density, backpressure and precious-metal content matter to an aftertreatment system — that is a reason to confirm the maker, not a claim we make about our own stock.

Frequently Asked Questions

Are Cummins 5579357 and 5295606 DPFs interchangeable?

They belong to the same ISC and ISL aftertreatment family but correspond to different emissions eras and calibrations. Confirm the engine serial and the number off the removed unit rather than assuming a direct interchange.

What does the 5579357 DPF kit include?

The kit is commonly listed with gaskets 2871452 and V-band clamps 2871862. Confirm the exact contents per quotation, as composition varies by supplier.

How do I confirm I need 5579357 and not another ISC/ISL DPF?

Match the engine serial and the number stamped on the removed unit against the emissions era. EPA07, EPA10 and EPA13 DPFs are not interchangeable.

Is a DPF a filter I replace like an oil filter?

No. A DPF is long-life aftertreatment hardware, and a DPF fault is often a symptom of an upstream service problem rather than a part to swap.

Can I get a genuine Cummins DPF instead of an alternative?

Declare it before quoting. We quote genuine original references as such, and label any alternative clearly.

Confirm the era. Then confirm the number.
