Genuine Fleetguard LF14000NN Oil Filter (Pack of 6) | OEM NanoNet® Synthetic Media for Cummins ISX & X15 Engines

Genuine Fleetguard LF14000NN Lube Filter (Pack of 6 Bulk Savings Set) – Fleetguard Filtration by Cummins

Protect your heavy-duty diesel engine with the ultimate in lubrication technology. This 6-pack bundle of genuine Fleetguard LF14000NN lube filters features patented NanoNet® 100% synthetic filtration media, delivering unmatched cold-start protection, superior contaminant trapping, and extended oil drain interval capability.

Designed specifically for Cummins ISX and X15 diesel engines (as well as select Detroit Diesel, Caterpillar, and PACCAR platforms), the LF14000NN upgrades previous-generation LF9009 / LF14000 filters by reducing oil flow restriction while trapping micro-particles that cause wear on bearings and cylinder liners.

Buying in a Pack of 6 gives fleet operators, owner-operators, and service shops bulk discount pricing with convenient stock on hand for scheduled maintenance overhauls.

Frequently Asked Questions (FAQ / Q&A)

Q: Is the LF14000NN an upgrade over the older LF9009 filter?

A: Yes! The LF14000NN features Fleetguard's proprietary NanoNet® synthetic media, replacing the older cellulose/synthetic blend media found in the LF9009. It provides much higher dirt-holding capacity, better cold-flow performance, and finer particle trapping without restricting oil flow.

Q: Are these genuine Fleetguard / Cummins OEM products?

A: Absolutely. At Valtrix Powertrain, every item in this 6-pack is 100% authentic Fleetguard product directly from authorized distribution channels. We never sell counterfeit, remanufactured, or second-rate knockoffs.

Q: What is the benefit of NanoNet® synthetic filtration media?

A: NanoNet® media is composed of polymer fibers thousands of times thinner than a human hair. Unlike traditional cellulose paper filters that can degrade or allow small abrasive dust particles through, NanoNet maintains structural integrity under extreme heat/pressure and traps microscopic soot and debris before it damages bearings.

Q: What size engine oil threads does the LF14000NN use?

A: The LF14000NN utilizes standard M95 x 2.5-7H metric threads with a heavy-duty rubber gasket engineered for high-pressure diesel oil systems.
