Comparing the numbers
Figures come from each manufacturer as published, and equivalents rarely match to the millimetre. Thread pitch and gasket diameter have to match for the filter to seal at all. For height, diameter and bypass pressure, check the difference against what your engine manufacturer allows before fitting.
