Every California smog check term and question, plainly defined
What should I know about Dodge smog checks in California?
Dodge vehicles pass California smog reliably when stock and maintained, but the Charger, Challenger, and Durango with HEMI V8 engines are popular modification targets — aftermarket exhaust and intake components without CARB EO numbers cause visual inspection failures.
5.7L and 6.4L HEMI V8 (Charger, Challenger, Durango 2006+): Multi-Displacement System (MDS) cylinder deactivation carries lifter wear risk similar to GM AFM — misfire codes on high-mileage examples
6.2L Supercharged HEMI (Hellcat, Redeye, Jailbreak 2015+): heavily modified examples are extremely common; all emission-related aftermarket parts must have CARB EO numbers
Dodge Charger/Challenger SRT Hellcat: cold-air intakes, catback exhausts, and headers are popular — each component must have a CARB EO number to pass visual inspection
Dodge Durango 3.0L EcoDiesel (2014-2015): subject to diesel emissions recall; verify recall completion before testing
Dodge Challenger 3.6L Pentastar V6: reliable emissions record; rare failures typically EVAP-related on older models
Dodge Ram and Charger pursuit vehicles (fleet): fleet smog accounts available with consolidated billing
Per BAR inspection data, CARB EO certification database, and Chrysler/Dodge TSB documentation.
