I feel like every time I open my hood my filter minder is set to the "replace filter" and I have to reset it. Recently cleaned my filter. Noticed I have the old part number (already put it back on truck) and saw a few threads on the web referencing a new part number (8C3Z9N622A). Does this minder do anything other than visually tell you that your filter needs replacing or will it effect performance. 2008 6.4 - Early model as it seems they changed to a new filter minder according to the Google. I am tuned and deleted running an S&B intake.
When it gets "bad" enough you'll get a light on the dash. For whatever reason when I run a Wix filter it trips the light in a few thousand miles, can reset and it trips almost immediately. Is also an early '08.
My filter minder was tripping easily as well. Tested it with a Mityvac and it only needed 5 in Hg vacuum. Too sensitive. Just unhooked and plugged hole. Been meaning to put a mechanical type that registers restriction.
