description: Fleetguard FF5971NN NanoNet Fuel Filter 6-Pack — Genuine OEM 4-Micron Extended-Life Filter for 2020+ Cummins X15 & X12 Engines The Fleetguard FF5971NN 6-Pack is a case of six genuine Cummins Filtration NanoNet spin-on fuel filters designed for 2020 and newer Cummins X15 and X12 engines with EPA 2017 and EPA 2021 emission ratings. This is the MOST ADVANCED fuel filter in the Fleetguard lineup — featuring proprietary NanoNet synthetic media that delivers 4-micron filtration at 99.2% primary particle efficiency, providing the finest fuel filtration available for Cummins heavy-duty diesel engines. The FF5971NN's headline feature is its 75,000-mile service interval — three times longer than the standard FF5776 (25,000 miles). This extended service life means fewer filter changes, less maintenance downtime, and lower total cost of ownership for fleet operators. The NanoNet media holds significantly more contaminant at consistent differential pressure compared to the older StrataPore (FF5776) and first-generation NanoNet (FF5825NN), delivering sustained protection throughout the entire extended interval. The FF5971NN is the direct replacement for Cummins OEM 5575143 and is backwards-compatible with FF5825NN — meaning it fits the same M90 x 2-7H mount. However, it is 2.6 inches TALLER than the FF5776 (11.5" vs 8.9"). Verify clearance before upgrading from FF5776. Trusted by fleet managers, owner-operators, and diesel shops running 2020+ Freightliner, Kenworth, Peterbilt, International, and Volvo trucks with Cummins X-Series engines.
