Compatibility Notes:
- Automotive retail fitment consistently lists 2003–2007 5.9L Ram coverage for 3949692.
- Mopar cross-ref 5086857AA appears in dealer catalogs for 2003–2012 applications with engine/transmission caveats (e.g., manual trans, not for certain 2010+ autos). Always confirm by VIN/ESN and build data.
- Cummins’ catalog labels 3949692 as an Oil Suction Connection and notes primary use on some EPA13 ISB/QSB 6.7 engines in industrial contexts; this reinforces the need for ESN validation outside 2003–2007 Ram 5.9L.
