nice.
So where does the stock air filter fall in on this chart?

I unfortunately do not have access to any data surrounding the stock filter

Would my logic be correct in that an air filter that has the lowest DPMO also is more air restrictive (therefore not providing the typical gains seen from dropin filters (k&N filters since they are most common on this forum)

generally. There could be a filter with a very low DPMO but also has a high flow... but then again things like that would probably cost more than people are willing to pay and so no one bothers to make one. Its all possible..

P.S i would assume the stock filter has a low DPMO and also doesn't flow very well... because as much as we want to believe otherwise, Nissan won't put a filter in there that could cause engine damage and thus have them to pay out on a warranty fix. They will be overly cautious to protect their money.

often but not always

things get even trickier when you start comparing "real world" loaded flow numbers for the filters. That's a topic for someone with more schooling than me.
