Cummins® ISX / X15 Engines

We’ve been recommending our full-flow lube filters for ISX / X15 engines for decades. The fact is, our family of ISX / X15 lube filters still perform better where it counts – whether comparing to older stacked disk or the current OEM stacked filter arrangement.

Donaldson filters provide superior contaminant holding capacity (longer filter life) and filtration efficiency (contaminant removal). No matter how you stack it – Donaldson filters deliver better engine protection and provide better protection for your ISX / X15 engines than Fleetguard® LF14000NN filters.
