Paccar DPF Filters for Diesel Aftertreatment Systems

Diesel particulate filters trap soot produced during combustion before it exits the exhaust system. During regeneration cycles, the engine management system burns off accumulated soot to maintain proper exhaust flow and emissions performance.

Common Paccar Engine Applications

Paccar DPF filters are widely used on modern diesel engines operating in Kenworth and Peterbilt trucks.

• Paccar MX-11 diesel engines
• Paccar MX-13 diesel engines
• Kenworth T680 and T880 trucks
• Peterbilt 579 and 567 truck platforms

Each DPF filter is engineered to meet the exhaust flow and emissions requirements of the Paccar aftertreatment system.

Common DPF Filter Failure Symptoms

• DPF or emissions warning lights
• Frequent regeneration cycles
• Excessive exhaust backpressure
• Engine derate conditions
• Reduced engine performance

DPF filters may become restricted due to soot overload, ash accumulation, or internal damage. Replacing a clogged or damaged filter helps restore proper exhaust flow and aftertreatment system operation.

Verify Fitment Before You Buy

DPF filters vary depending on engine configuration, emissions system setup, and truck model year. To confirm compatibility before ordering, provide:

• Engine serial number
• Truck year / make / model
• Current DPF part number
• Photos of the filter or identification tag if available

This information helps ensure the correct Paccar DPF filter is selected for your truck.
