Detailed Product Description

The Baldwin B281 engine oil filter is engineered to provide effective filtration and protection for a range of heavy-duty equipment and generators.

With a height of 5 3/8 inches (136.5 mm) and an outside diameter of 3 11/16 inches (93.7 mm), this filter fits applications requiring an M22 x 1.5 thread size.
