Stock air box on our 2007 fjcruiser. I've tried wix,Napa, stp,champion, Purolator, super tech( only one made in USA btw) and a few others.
The element is too loose/ short and does not seal. This allows dirt to completely bypass the filter.
Napa is ordering me a denso. If that does not fit what next? Can the plastic housing " grow" over time.

I had a problem like this on my wife's Hyundai. Pretty much got told I was stupid and didn't know what I was doing. This looks a bit worse than air filter letting dirt by problem.
I tried every filter I could get, a Bosch seems to fit pretty good.
Yeah if the filter just jams in there to make a tight seal, it seems to get loose over time. As in 4 years or so time.
Might be time to get an k&n aftermarket intake, in theory it should let less dirt though.
