ATRACYPART LF14000NN Oil Filter for Cummins ISX ISM X15 M11 QSX QSM QST — Heavy-Duty Metal Housing, High-Efficiency Media

The ATRACYPART LF14000NN is a heavy-duty oil/lube filter engineered to trap fine contaminants while maintaining steady oil flow for Cummins ISX, ISM, X12, X15, M11, QSX, QSM and QST diesel engines.

Built to meet the demands of commercial diesel applications, this replacement filter combines high-efficiency media with a corrosion-resistant metal housing and precision seals. It replaces common OEM numbers including LF9080, LF9001, 4367100, BD7154, and 57746XD, making it a practical choice for fleet maintenance, over-the-road trucks, vocational vehicles and coaches using Cummins platforms.

How does the LF14000NN protect engine components?

The LF14000NN uses multi-layer filtration media designed to capture microscopic particles that can accelerate wear. By reducing abrasive contaminants in the oil, it helps preserve bearings, camshafts, and other critical parts without creating excessive restriction to oil flow.

• High-performance media captures fine particulates while permitting consistent oil circulation.
• Metal housing resists deformation under pressure, keeping the filter element stable.
• Quality seals prevent bypass and minimize the chance of leakage during operation.

Will this filter fit my Cummins-powered truck or coach?

This filter is compatible with a wide range of Cummins engines—ISX, ISM, X12, X15, M11, QSX, QSM and QST—found in many heavy-duty and commercial vehicles. Use the listed replacement numbers to verify fitment against your vehicle’s service manual or parts lookup before purchasing.

• Replaces LF14000NN, LF9080, LF9001, 4367100, BD7154, 57746XD.
• Commonly used in Freightliner, International, Peterbilt, Kenworth, Volvo, Western Star and similar chassis.
• Check OEM cross-reference or vehicle parts guide for exact application match.

What makes the LF14000NN durable for heavy-duty service?

Durability comes from a rugged metal canister treated against corrosion and engineered to withstand high temperatures and pressures typical in diesel service. Combined with robust internal media and reinforced endcaps, the filter resists collapse and maintains performance over its service interval.

• Corrosion-resistant metal housing for long-term structural integrity.
• Heat- and pressure-resistant construction suited to heavy-duty cycles.
• Precision seals to maintain a leak-free installation under stress.

How should I install and maintain this filter?

Installation follows standard oil filter replacement procedures—drain, remove old filter, inspect mounting surface, lubricate gasket, and hand-tighten the new unit to spec. Regular oil and filter change intervals should follow engine manufacturer recommendations and operating conditions to ensure ongoing protection.

• Inspect gasket and mating surface for debris before installing new filter.
• Lubricate the gasket with clean oil and tighten according to torque or turn-count specs.
• Use matched oil grade and service intervals from the engine manufacturer for best results.

Who is this for: The ATRACYPART LF14000NN is aimed at fleet managers, service technicians, owner-operators and maintenance shops that run Cummins-powered heavy-duty vehicles and need a reliable, cross-referenced replacement oil filter. If you maintain long-haul trucks, vocational rigs, buses or coach fleets and require a robust filter that matches common OEM part numbers, this filter provides an efficient, durable option.
