5418486 | Genuine Cummins® Outlet Catalyst Module EPA17 6.7L ISB/QSB

Description: Outlet Catalyst Module Condition: New Brand: Cummins® Part Number: 5418486 Vehicle Fitment Freightliner M2 106 — 2022–2024, B6.7 EPA21 FCCC (Freightliner Custom Chassis) — 2022–2024 B6.7, approximately 280–325 HP, EPA21. Navistar/International — 2022–2024 B6.7/L9 The Outlet Catalyst Module is an OEM exhaust aftertreatment component engineered for heavy-duty commercial diesel engines to eliminate nitrogen oxides (NOx) and regulate tailpipe emissions. Reduce Harmful Pollutants Converts carbon monoxide (CO), unburned hydrocarbons (HC), and sometimes nitrogen oxides (NOx) into less harmful substances like carbon dioxide, nitrogen, and water vapor. Assist Diesel Particulate Filter (DPF) Regeneration In some designs, it helps raise exhaust temperature to burn off trapped soot in the DPF, keeping the filter clean and efficient. Meet Emissions Regulations Helps vehicles comply with strict emission standards like EPA, Euro 5, Euro 6, or similar local regulations. Protect the Environment and Health By reducing pollutants, it limits air pollution, smog, and health risks associated with diesel exhaust. Improve Engine Efficiency and Longevity Proper emission control prevents soot buildup downstream, reducing stress on other components like the turbocharger or muffler Signs of Faulty Check Engine or DPF Warning Light Dashboard lights may illuminate, indicating an aftertreatment problem or inefficient catalyst performance. Reduced Engine Performance The engine may lose power or accelerate sluggishly because a blocked or damaged catalyst restricts exhaust flow. Increased Fuel Consumption The engine may work harder to maintain performance, consuming more fuel than usual. Excessive Smoke or Unusual Exhaust Color Black or dark smoke may appear if the catalyst isn’t properly converting hydrocarbons or assisting DPF regeneration. Frequent Regeneration Cycles If the Outlet Catalyst Module isn’t functioning, the system may attempt DPF regeneration more often, sometimes unsuccessfully. Strange Smells A burning or chemical odor from the exhaust may indicate the catalyst is overheating or failing. Limp Mode Activation Many modern diesel vehicles will reduce engine power to protect the engine if the module is severely blocked or malfunctioning. Failed Emissions Test A malfunctioning outlet catalyst will often cause the vehicle to fail emissions inspections due to higher pollutants in the exhaust.
