What a DPF Filter Does

A diesel particulate filter captures soot particles from the exhaust stream before they exit the tailpipe. The filter stores these particles until they are burned off during a regeneration cycle. This process helps reduce particulate emissions and keeps diesel engines compliant with modern emissions regulations.

Common Engines Using DPF Systems

DPF filters are used across many heavy-duty diesel engines including:

• Cummins ISX, X15 and ISB 6.7 engines
• Detroit Diesel DD13, DD15 and DD16 engines
• Paccar MX-13 and MX-11 engines
• Volvo D11, D13 and D16 engines
• Mack MP7, MP8 and MP10 engines
• International A26 and MaxxForce engines
• Hino J08 and A09 engines

Common Signs of DPF Filter Problems

• Frequent regeneration cycles
• DPF restriction or soot load fault codes
• Loss of engine power
• Engine derate conditions
• Excessive exhaust backpressure
• Check engine or emissions warning lights

When a DPF filter becomes restricted or damaged, the exhaust system cannot properly manage soot buildup. This can lead to engine derate conditions and reduced vehicle performance.

Importance of Correct DPF Fitment

DPF filters are engine-specific and emissions-system specific. Installing the wrong filter can cause exhaust flow restrictions or emissions system faults. To confirm compatibility quickly provide:

• Engine serial number
• Current DPF part number
• Truck VIN number
• Year / Make / Model of truck
• Photos of the DPF tag if available
