FAQs
Are all Kohler oil filters the same size?
No, Kohler oil filters are not all the same size; different Kohler engines use different filter lengths, diameters, and thread types, so it’s important to match your engine model or OEM part number with the correct replacement.
What oil filter does a Kohler engine take?
A Kohler engine typically uses OEM filters such as 12-050-01-S, 12-050-08-S, 12-050-16-S, or 52-050-02-S, but the exact filter depends on the engine family, Command, Courage, 7000 Series, or Aegis, so always check the conversion chart or engine manual.
How to check oil filter compatibility?
To check oil filter compatibility, match the OEM Kohler filter number with a cross-reference chart, verify thread size and gasket diameter, ensure similar micron rating and overall length, and confirm it fits properly without leaking during installation.

Can you use a Briggs & Stratton oil filter on a Kohler engine?
Yes, some Briggs & Stratton oil filters can fit Kohler engines because they share common threads and sizes, but only certain models are interchangeable, so you must verify the OEM number and cross-reference before using one.
What oil filter fits the Kohler 7000 series?
Most Kohler 7000 Series engines use the Kohler 12-050-01-S or 52-050-02-S oil filter, which cross-reference with common aftermarket filters such as Fram PH3614, Wix 51348, and Napa Gold 1348.
What is the difference between 492392 and 492392s?
The difference between 492392 and 492392S is mainly the suffix, “S” indicates an updated or superseded part from the manufacturer, meaning 492392S replaces 492392 with the same fit and performance but improved design or packaging.
