Fleetguard LF14009NN spin-on lube filter for Cummins ISL9 / L9 and other Cummins applications spec'd for premium-efficiency oil filtration. Combines 2-in-1 NanoNet® and StrataPore® media to deliver substantially higher particle-removal efficiency and contaminant-holding capacity than the LF9009 it supersedes — meaningful protection under cold-start and high-soot duty cycles. Replaces Cummins 5444774.
