Oil filters
Mahle OC 574
A spin-on oil filter published with a complete dimensional specification — M20×1.0 thread, 68 mm diameter, 65 mm height — and a stated bypass valve, for Aprilia, Sachs and Suzuki among others.
What the seller commits to paper
Spin-on filter. Height 65.0 mm. Diameter Ø 68.0 mm. Thread M20×1.0. Bypass valve: yes.
One bullet, four specifications and an answer to a design question.
The thread is the line to read twice
The MANN-FILTER listing in this same family publishes M20×1.5 at 66 mm diameter and 65 mm height.
Compare: 68 against 66 millimetres of diameter. 65 against 65 millimetres of height. And M20×1.0 against M20×1.5.
Two filters that look the same on a shelf, measure almost the same in a hand, and do not thread onto the same engine. It is the single most useful comparison in this family and it exists only because both makers published their threads.
The bypass valve
Oil has to keep moving. If the element blocks — or if cold oil is too thick to pass — something has to let it through unfiltered rather than starve the engine. Some engines carry that valve; some filters do. This listing says this filter does, and nothing else on this shelf addresses it either way.
The rest of the bullets
“A broad portfolio in original-equipment quality”, “durable and reliable”, “easy to clean and maintain”, “quick and straightforward to fit”. Those are filler around the one bullet that does the work.
