Baldwin Filters B37 Spin-on Oil Filter 2.56in Od

Product Description

The BALDWIN FILTERS B37 is a spin-on automotive oil filter designed to remove contaminants from engine oil during normal operation. With an outside diameter of 2.56 inches and an overall length of 3.5 inches, this filter fits a range of light-duty automotive applications. The spin-on design allows for straightforward removal and installation without special tooling. An included gasket ensures a leak-free seal at the mounting surface. The B37 is suited for installation by automotive technicians and experienced DIYers performing routine oil service.

The B37 is used in passenger vehicle and light truck applications requiring a compact spin-on oil filter. Its high-capacity filtration media targets wear particles and other contaminants that accelerate premature parts failure. The 3/4-inch thread size is common across a wide range of domestic and imported engine platforms. This filter is a direct replacement for several cross-reference part numbers from major filter brands, making it a practical choice for shops sourcing across multiple supplier lines.

Installation Notes

Oil filter replacement is performed by automotive technicians or qualified DIYers as part of routine engine oil service. Always drain and dispose of old engine oil before removing the filter. Hand-tighten the new filter until the gasket contacts the mounting surface, then follow the filter manufacturer's final tightening guidance rather than relying on torque values not specified for this unit. Verify there are no leaks after startup before returning the vehicle to service.
