Re: M11 slight overheating and oil loss? Reply #20 – September 20, 2019, 09:13:22 pm Yup.After first drive with some WOT at higher RPM AFTER replacing filter element, make a note of the air filter minder reading.This is now the "base line" from which the filter will start to clog/increase restriction.But, be aware that there are ways that a filter can fail that will not be indicated by a filter minder. A tear in a pleat (particularly likely if one tries to "clean the filter" by banging it on a hard surface), break down from water, etc will actually reduce restriction (yes, and allow lots of dirt into the engine resulting in what is known as "dusting").Installing the incorrect filter element can cause the filter to collapse, resulting in dusting/low filter minder readings. Though two filters could have exactly the same dimensions, they may not be interchangeable. Support for the filter media depends on direction of air flow-- from outside to inside or inside to outside. Neither direction is better/worse, but if the structure supporting the filter media is not correct, the filter element can indeed collapse. Quote Selected
