Baldwin B309 oil filter matches
Compare Baldwin B309 against compatible oil filters from other brands. Review thread size, gasket dimensions, height, valve behavior, and fitment notes before substituting. This is a research tool, not an automatic guarantee of fitment.
Before substituting: verify filter style, thread size or cartridge dimensions, gasket dimensions, height and clearance, bypass behavior, and your engine or equipment requirements.
