Dorman 674-2002 Diesel Particulate Filter (DPF)

Dorman 674-2002 Diesel Particulate Filter

The Dorman 674-2002 diesel particulate filter is built as a specific-fit replacement for the original DPF on selected diesel vehicles. It is engineered to match OE fit and function while using a stainless steel body and silicon carbide substrate for durable exhaust filtration.

Key Features

• Specific-fit diesel particulate filter for direct replacement applications
• Stainless steel body construction for exhaust system durability
• Silicon carbide substrate material for particulate filtration performance
• Flanged inlet and outlet connections for OE-style installation
• Designed to match the fit and function of the original filter
• Compatible with applications that use 13-inch inlet and outlet outside diameters
• Part number 674-2002 for catalog and service reference

Detailed Description

Dorman 674-2002 is a diesel particulate filter replacement for vehicles that require a specific-fit DPF with flanged inlet and outlet connections. The stainless steel housing and silicon carbide substrate are selected for exhaust-system durability and consistent filtration performance. For buyers searching for a diesel particulate filter for Dorman 674-2002, or a direct replacement DPF for diesel exhaust service, this part is built to align with the original filter’s fit and function on the specified vehicle application. It is also a relevant option for diesel truck and commercial-duty service where OE-style exhaust fitment matters. This part cross-references Monroe Shocks & Struts (e.g., 20863859, C0021) for the same application.

What It Helps Address

• Restricted exhaust flow caused by a loaded or failing DPF
• Diesel particulate filter warning lights tied to filtration efficiency issues
• Exhaust service needs on vehicles requiring a specific-fit replacement
• Fitment problems from worn or damaged OE filter assemblies
• Noise, odor, or drivability concerns related to exhaust aftertreatment faults

Installation Notes and Tips

Verify the vehicle’s exhaust configuration before ordering, including flanged inlet and outlet connections and the listed diameter requirements. This DPF does not include inlet or outlet gaskets or mounting hardware, so confirm the existing service parts are reusable or source the correct replacements separately. Because fitment is specific, compare the original unit to the Dorman 674-2002 before installation. Fits the listed diesel vehicle application only; use the OE part number and exhaust measurements to confirm compatibility.

Quality Assurance

Dorman designs this diesel particulate filter to match the original part’s fit and function on specified vehicles. The stainless steel construction and silicon carbide substrate support reliable service in heavy-duty exhaust applications. Part number 674-2002 is intended for direct replacement use where the original DPF specification is required.
