Paccar MX13, X12 DPF Filter 2018-2024: OEM 4394764
Advanced Filtration for Heavy-Duty Duty Cycles: PACCAR MX13, X12 DPF Filter (2018–2024, OEM 4394764)
What is it?
The PACCAR MX13, X12 DPF Filter (OEM 4394764) is a Diesel Particulate Filter engineered for the MX13 and X12 engine architectures used in heavy-duty trucks from roughly 2018 through 2024. Its role is to capture soot and fine particulate matter from the exhaust gas before it exits the after-treatment system, helping ensure emissions compliance and protecting downstream components.
Why Choose the PACCAR MX13, X12 DPF Filter (OEM 4394764)?
This DPF is made to PACCAR’s original equipment standards—matching mounting flanges, sensor ports, substrate design and flow dynamics specified by the engine manufacturer. Choosing an OEM-specified filter like part 4394764 ensures correct installation, reliable exhaust behaviour, minimal installation complications and long-term system integrity.
Key Benefits
✅ OEM Match Fitment: Designed to align directly with factory exhaust mounts, sensor interfaces, and flow paths.
✅ Heavy-Duty Construction: Built to withstand high temperatures, vibration, heavy soot loads and long service intervals.
✅ Effective Particulate Capture: Traps soot and fine particles to support emissions compliance and system health.
✅ Stable Regeneration Behaviour: Designed for consistent performance during regeneration cycles, reducing risk of fault codes or regeneration failures.
✅ System Longevity: Cleaner exhaust flow entering SCR, catalysts and sensors leads to extended downstream component life.
Applications
This filter is suitable for heavy-duty trucks equipped with the PACCAR MX13 or X12 engines from the model years 2018–2024. It's ideal for long-haul, regional-haul or vocational platforms where emission performance, durability and uptime are critical.
Installation Notes
As a direct-replacement component, this DPF should be installed by a qualified technician. Before installation, verify compatibility with your engine model year and verify the part number OEM 4394764. Remove the old unit carefully, inspect clamps and gaskets for corrosion or wear, clean mating surfaces thoroughly and ensure no debris enters the system. Install the new DPF, torque bolts to manufacturer specification, reconnect sensors and wiring harnesses. After installation, clear any diagnostic codes and run the engine through a monitored operating cycle—observing back-pressure, exhaust temperature, and regeneration behaviour—to confirm the system is functioning properly and without leaks.
Final Thoughts
Reliable DPF performance is essential for modern heavy-duty engines. The PACCAR MX13, X12 DPF Filter (2018–2024, OEM 4394764) delivers OEM-level precision, durability and compatibility—helping your vehicle maintain emission compliance, protect after-treatment components and stay productive mile after mile.
