The BALDWIN FILTERS B109 is a spin-on automotive oil filter designed for engine lubrication system maintenance. It filters contaminants from engine oil to protect internal engine components during operation. With an outside diameter of 3.75 inches, an overall length of 5.3125 inches, and an M20x1.5 thread size, it installs directly onto compatible engine oil filter mounts. This filter is typically serviced by automotive technicians and fleet maintenance professionals during routine oil change intervals.
The B109 is suited for automotive and light-duty commercial applications where a spin-on oil filter with M20x1.5 thread fitment is specified. It is appropriate for use in scheduled preventive maintenance programs and is sold in minimum order quantities of 12 units, making it practical for shop stock or fleet service operations.
Designed as an OEM-style replacement spin-on oil filter for automotive engines requiring an M20x1.5 thread mount with a 3.75-inch outside diameter and 5.3125-inch overall length.
Installation is performed by automotive or fleet maintenance technicians. Before replacing the filter, shut off the engine and allow it to cool to reduce hot oil exposure risk. Use an appropriate filter wrench for removal and hand-tighten the new filter according to the filter and vehicle manufacturer guidelines. Dispose of used oil and the spent filter in accordance with local environmental regulations.
