What This Page Covers
A category hub for Cummins engine-service filters, service kits and aftertreatment filters used across industrial equipment, generator sets, plant and marine installations. The installed arrangement determines which categories apply.
Engine-Service Filtration
- Fuel filtration
- Lube oil filtration
- Air filtration
- Fuel/water separation
- Coolant filtration
- Crankcase ventilation, where specified
Aftertreatment & Service Scope
DEF filters and diesel particulate filters are included as separate aftertreatment categories. Check the installed system and complete part reference. Hydraulic, transmission and cab filters remain outside this directory.
Availability is confirmed in the quotation. This page is not a live stock list; the offered item also needs confirmation.

Engine Build
Engine Build
The engine model narrows the search. The serial or build number, installed position and full reference determine what needs to be checked.
Cummins Filters by Installed Position
Engine and aftertreatment systems can use several filter positions. Identify the role of the removed element before reviewing a replacement.
| Filter Position | What to Confirm |
|---|---|
| Fuel/water separator | Complete reference, bowl arrangement, connections and any water-in-fuel sensor. |
| Primary fuel element | The installed stage and its specified reference, rather than appearance alone. |
| Final-stage fuel element | The correct final-stage reference for the engine build. |
| Lube oil filter | The full-flow reference and whether a separate bypass element is specified. |
| Main and safety air elements | Housing reference and the distinct part number for each element. |
| Coolant filter | Whether one is specified, together with coolant and treatment requirements. |
| Crankcase ventilation filter | The engine record and the installed ventilation service arrangement. |
| DEF filter | Installed DEF supply-module arrangement and complete filter or kit reference. |
| Diesel particulate filter (DPF) | Aftertreatment assembly reference, emissions configuration and required kit contents. |
A cross-reference is a candidate to review. A similar number, thread or external dimension does not by itself confirm media, seals, valves or application suitability.
Find Filters by Engine Series
Start with the engine family, then confirm the serial or build number. Production, emissions and installation arrangements can change the required filter references.
4BTA / 6BTA
Identify the B Series model, then include the serial or build number and the complete references from the installed filters.
Request B Series Filters →QSB6.7
Keep the full engine designation with its serial number. Identify each installed filter position before reviewing a replacement reference.
Request QSB6.7 Filters →QSL9
Prepare the filter list against the QSL9 engine record. Include the existing references so each requested service item can be reviewed.
Request QSL9 Filters →QSX15
For a QSX15 service enquiry, list the required filter positions and quantities together with the complete engine identification.

Five Records to Confirm Before Ordering
Have these details ready when you request a quote, whether you need a single filter or a complete service set.
Include These Five Details
Engine identification
Provide the engine model and full serial or build number. The model badge alone does not identify every filter arrangement.
Installed filter position
Identify separator, primary fuel, final-stage fuel, oil, air, coolant, crankcase ventilation, DEF or DPF as applicable.
Complete filter part number
Copy the full reference from the removed element, including every prefix and suffix.
Quantity and service scope
State whether you need one filter or a service set, with the quantity required for each item.
Original or alternative requirement
Specify whether a genuine original item is required or a labelled alternative is acceptable. Include any procurement, compliance or warranty requirements.
Where Filter Fitment Goes Wrong
Similar appearance and familiar references can hide a different application. Review these common mix-ups before confirming an order.
Primary or Final-Stage?
Similar-looking fuel elements may serve different stages. Appearance alone does not establish which position an element belongs in.
Check the positionKeep the installed stage with the complete filter reference.
Main or Safety Air Element?
Identify each element separately. The main and safety elements occupy distinct positions within the installed air-filter arrangement.
Check each elementConfirm the housing and separate part reference for each position.
Cross-Reference or Confirmed Match?
A reference list narrows the search. It does not by itself establish media, seals, valves or the full application specification.
Check the applicationReview the offered item against the engine build and installed arrangement.
Complete or Superseded Number?
An omitted prefix, suffix or changed reference can lead the search in the wrong direction. Keep the complete identification from the removed element.
Check both referencesWhere a number has changed, retain the old and current references for review.
Frequently Asked Questions
What filters does a Cummins engine have?
The arrangement depends on the engine build and installation. Review fuel/water separation, fuel, oil and air positions, together with coolant or crankcase ventilation filters where specified. DEF and DPF filters belong to the aftertreatment system and should be identified separately.
How do I find the right Cummins filter for my engine?
Start with the full serial or build number, installed position and complete number on the removed element. The model name alone is not enough to confirm a match.
Can I request an alternative filter?
State whether your specification permits an alternative or requires a genuine original item. Review the offered maker and complete reference before accepting a replacement.
Why does my cross-reference show a different number?
Possible reasons include different numbering systems, a superseded reference or an application variation. Keep both numbers and review them against the engine build and installed arrangement.
Which filter kit fits my engine?
Confirm the engine identification, service scope and required positions first. Review each item and quantity in the proposed kit rather than assuming one set covers every engine with the same model name.
