SummaryOn Cummins diesel applications that are for 2019 and newer the bpro part 1BP00507AB can on occasions create a check engine light. In these situations, it is recommended to use the appropriate Mopar air filter (57008652AA). The "AC" level of the part is in development to resolve this issue. 1BP00507AB should still be usable for 2018 and older Model year Cummins engines.
