PRODUCT DESCRIPTION

Multi OE LF3349 Lube Oil Filter for Cummins Engine

This OEM standard lube oil filter carries cross reference part numbers LF3349,1012N-010 and 3937743, professional DCEC and Cummins engine accessory. High efficiency filter paper intercepts fine impurities effectively, preventing abrasive particles from circulating inside engine lubrication circuits. The reinforced metal canister and nitrile rubber seal deliver stable sealing performance under extreme temperature changes. Direct spin-on installation supports quick replacement without complicated modification, perfectly matching the original oil filter mounting structure of Cummins diesel engines for heavy trucks.

Reduce Engine Wear & Avoid Lubrication System Faults

Dirty engine oil mixed with metal powder and carbon sludge will scratch crankshaft, bearings and cylinder walls, shortening the service life of Cummins power assemblies. Our LF3349 oil filter solves this common failure for DCEC engine users. It continuously purifies circulating lubricating oil during equipment operation, lowering the risk of premature engine wear and unexpected breakdown. Suitable for fleets and construction sites with long continuous working hours, this lube filter helps users cut expensive engine overhaul costs.

OEM Spec Production & Strict Factory Quality Inspection

LF3349 lube oil filter is manufactured strictly according to original drawing specifications as genuine Cummins spare parts. Every finished filter passes bubble tightness test, flow resistance inspection and filtration efficiency testing before warehousing. Widely adopted for DCEC powered heavy trucks, generator sets and construction machinery, this oil filter has accumulated massive practical verification in global heavy-duty working scenarios. Thickened shell structure resists vibration and pressure impact during long-distance vehicle driving.
