Cummins Engine Filters: ISX, ISB, X15 & QSX
One stop for ISB6.7, L9, ISX/X15, ISM, and QSX filtration.
A Cummins ISX or X15 in a long-haul tractor is designed to run a million miles before its first overhaul. To do that, the engine has to be fed clean fuel, clean oil, and clean air across every one of those miles. Cummins designed the engine. The filters are what make the design hold.
Steinberg stocks 13 filter SKUs across the Cummins families that run most of America's freight: ISB6.7 and QSB; ISL9 and L9; ISM; ISX, ISX15, and X15; ISX12; and QSX. Fuel filters, water separators, lube filters, and engine intake air, paired by engine generation and EPA regulation set. Each is cross-referenced to Fleetguard FF, FS, and LF series part numbers and ships same-day from Hodgkins, IL. NET-30 terms for qualified fleet accounts.
For engine-specific catalogs see our Cummins ISX 15 / X15 Filters collection (the long-haul flagship) and our Cummins ISB 6.7 / B6.7 Filters collection (medium-duty programs). To browse by part type instead of engine, see our Fuel Filters, Lube Oil Filters, and Heavy-Duty Air Filters collections.
