Baldwin B495-SS vs WIX 51971MP: Oil Filter Compatibility
Compare Baldwin B495-SS and WIX 51971MP oil filters by compatibility, dimensions, thread size, gasket fit, bypass valve, anti-drainback valve status, and match confidence. Use this comparison as a fitment review, not as an automatic substitution guarantee. Both use a 15/8-12 thread.
Quick verdict
Closest known dimensional difference: height +10.4 mm. Verify application-specific requirements before substituting.
- Thread size is the first hard-fit check for any comparison of spin-on filters.
- Gasket OD and gasket ID are the most important seal-related dimensions.
- Height differences can matter for clearance even when thread and gasket fit appear close.
- Bypass and anti-drainback differences may be important, depending on the application.
