WIX 51810 vs Baldwin B105: Oil Filter Compatibility

Compare WIX 51810 and Baldwin B105 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 11/2-12 thread.

Quick verdict

COMPATIBLEMatch score: 87.5

Closest known dimensional difference: gasket ID +3 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.
