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...

91K on that sucker. I think the difference is that GM uses a equipment style air box where as the others do not. I know the 7.3 I had at work ran through air filters like crazy and they came out looking just like the one posted above. That had a direct intake of air off the front. My Duramax has the dust cone things on the bottom and also draws air from the fender well as a posed to the front. Thats why at the track you see missing headlights on the Duramax's, to suck in more air. Oddly enough these intakes are rated at 500RWHP.
