Description
Fleetguard LF14001NN extended-service spin-on lube oil filter for 2020+ Cummins X12 and X15 engines, replacing Cummins 5575298. It pairs StrataPore primary media with second-stage NanoNet to deliver 99% efficiency at 10 microns and 95% at 5 microns at 10 GPM. Same physical envelope as the LF14000NN, but built for the longer drain intervals of post-2020 X-platform engines.
