Can I trust that little gauge?????
Our 07 Dodge - 5.9 Cummins - has a gauge like this on the air filter The owner's manual says to depend on this gauge to tell you when to change the filter. In fact, on page 391 it says never...

Much like women, with filters, you just can't tell by looks whether they are good or not. :B
Yes the gauge is a good way to tell you whether the filter is good or not. They will tell you the exact restriction in the filter system.
