Does a 2007 Dodge Cummins have a DPF?
Whether a 2007 Dodge Cummins has a diesel particulate filter (DPF) depends on the engine option. The 6.7-liter Cummins introduced in 2007 uses a DPF, while the older 5.9-liter Cummins used in 2003–2007 generally did not.
This article explains the differences, how to identify which engine your truck has, and what that means for maintenance and emissions equipment.
Engine options in 2007 and DPF status
The following summarizes the Cummins engine options Dodge offered in the 2007 Ram lineup and whether they included a DPF as part of the exhaust aftertreatment.
- 5.9L Cummins Turbo Diesel (2003–2007 Ram 2500/3500) — DPF: Not fitted as standard; relied on older emissions controls such as EGR and a diesel oxidation catalyst (DOC).
- 6.7L Cummins Turbo Diesel (introduced in the 2007 model year) — DPF: Yes; includes a diesel particulate filter as part of the aftertreatment. Later years added DEF/SCR to meet evolving standards.
Bottom line: If your 2007 Ram has the 6.7L Cummins, it's equipped with a DPF. If it uses the 5.9L Cummins, it likely does not have a DPF.
How to verify on your truck
To confirm whether a specific 2007 Cummins has a DPF, use these checks:
- Inspect the exhaust system for a large post-treament canister labeled "DPF" or visually resembling a diesel particulate filter near the exhaust manifold or downstream piping.
- Check the engine code and documentation: a 6.7L engine designation indicates a DPF-equipped truck; a 5.9L means no DPF.
- Look for aftertreatment hardware: presence of a DEF (urea) dosing system suggests SCR-equipped later models; absence doesn't prove anything by itself, as early 6.7L setups used different configurations.
If you’re unsure after these checks, consult the VIN-specific build sheet or a Dodge/RAM dealership or a trusted diesel mechanic for confirmation.
Summary
The 2007 Dodge Ram Cummins lineup included two engines with different emissions equipment. The 5.9L Cummins did not use a DPF, while the 6.7L Cummins did, from its introduction in 2007 onward. Verification through engine badge, VIN, or physical inspection of the exhaust system will confirm the presence of a DPF on a specific truck.
What year did Dodge Cummins start using DEF?
Dodge/Ram Cummins engines started using Diesel Exhaust Fluid (DEF) around the 2013 model year for their heavy-duty pickup trucks to meet new emissions standards. While some models, such as the 2010 Chassis Cab trucks, had already begun using DEF, 2013 marked the year it was introduced on a wider scale for the main pickup truck lineup, replacing the older NOx absorption catalyst (NAC) system.
- 2010: The EPA implemented stricter emissions standards, and some 2010 models, such as the Chassis Cab trucks, began using DEF.
- 2013: Dodge/Ram introduced DEF on its heavy-duty pickup trucks (like the 2500 and 3500) as the standard for meeting emission regulations.
- 2007.5-2012: These model years do not use DEF but still had other emissions equipment like the Diesel Particulate Filter (DPF).
Does the 2007 6.7 Cummins have emissions?
The 6.7L Cummins debuted in 2007.5 with added emissions technology and a few upgrades to meet modern regulations.
Does a 2008 Cummins have a DPF?
Yes, a 2008 Cummins engine has a Diesel Particulate Filter (DPF) as part of its emissions system to meet federal regulations. This is particularly true for the 6.7L Cummins in Dodge Rams, which uses a DPF to capture soot and requires regeneration to stay clean.
- Purpose: The DPF traps soot and other particulate matter from the exhaust.
- Regeneration: To prevent clogging, the DPF needs to undergo regeneration, which is a process that burns off the accumulated soot.
- Regeneration types:
- Passive: Occurs automatically during highway driving.
- Active: Can be triggered when the truck is idling for too long, but older models may need to be driven to complete the process.
- Performance impact: A clogged DPF can lead to reduced engine performance, warning lights, and power loss. Avoid frequent short trips to help prevent excessive soot buildup.
