Why NanoNet® + StrataPore® Technology Matters

Modern Cummins X15 engines operate with tighter internal tolerances and higher operating pressures than previous generations. Fleetguard's exclusive NanoNet® and StrataPore® dual-layer filtration media captures extremely fine contaminants while reducing oil flow restriction, helping maintain optimal lubrication under heavy loads and during cold starts.

Compared to conventional oil filters, the LF14001NN provides greater contaminant capacity, improved filtration efficiency, and supports longer service intervals, making it an excellent choice for fleets and owner-operators focused on reducing maintenance costs and maximizing uptime.
