RYCO OIL FILTER Z436
In some instances, (Mazda Cx-5/7) this filter is superseded by the Z926.
This earlier filter has enough media to withstand a 10,000k service and matches the early factory oil filter design.
This superseding filter (Z926) has 50% more filtering media, to match the newer Mazda Filter design, and 15,000k service interval.
The Z926 does not have the anti-drain back valve of the earlier Z436 as it was deemed unnecessary.
