Fleetguard LF3970 full‑flow spin‑on oil filter is a high‑quality lube filter for Cummins diesel engines. Cross reference numbers: 3937736, 5404947, 14406393, B7177, P550428. Adopting StrataPore filter media with 30 micron efficiency (TWA 98.7%), it specially captures soot, metal particles and other harmful contaminants produced during engine combustion.
Lube oil acts as the life‑blood of diesel engines for friction reduction, component cooling and debris carrying. This spin‑on oil filter effectively removes abrasive impurities from circulating oil. Without proper filtration, accumulated contaminants will cause accelerated wear on engine moving parts and shorten overall engine service life.
With precise dimension and standard thread size 1 1/8‑16 UN‑2B, this LF3970 oil filter is easy for direct replacement. It is widely applied for heavy‑duty trucks, loaders and various construction machinery powered by Cummins engines.
