Cummins ISB 6.7L / B6.7 Filters

Cross-references span the 2017 ISB-to-B6.7 naming change.

The 6.7-liter Cummins is the engine that shows up where the Class 8 highway trucks do not. School buses on rural routes in the early morning. Garbage trucks in city traffic, where the cycle is start, brake, idle, start. Regional Freightliner M2 box trucks. Bluebird and Thomas Built buses. The duty cycle on each of those is harder on filters than the open highway is, because dust and water and stop-and-go run shorter intervals than steady RPM.

Steinberg stocks 7 filter SKUs covering the ISB6.7 / B6.7 program from the 2013 EPA refresh through Stage V (2020+). Three fuel filters (FF001, FF005, FF015), two water separators (FF021, FF022), one lube filter (FO001), and one engine intake air filter (FA005) for the Freightliner M2 platform that runs much of the medium-duty fleet service. Each is cross-referenced to Fleetguard FF-, FS-, LF-, and AF-series part numbers and ships same-day from Hodgkins, IL. NET-30 terms for qualified fleet accounts.
