I use Nissan stock 65FOC on The P11 and used them on the VE'd B15 as well. I've never had an issue with these Chinese made filters. I figure if Nissan was confident enough to use them on a brand new VQ35 engine and give it the same full warranty, the filters can't be all that bad. Yes, I have seen the inside of the filters. Having said that, I have never personally known somebody that had a 65F filter collapse or fail. I am not saying it hasn't happened, just that I haven't seen or heard of any specific failures of these filters (when used within the regular set conditions/mileage intervals). The one time I put an aftermarket filter on the B15 (in a pinch), I had an oil pressure issue. In the future, I
might run a premium aftermarket filter on the VE.
On a side note, here is a link to an oil filter comparison study. The study was for oil filters for a truck with a 5.7 Vortec engine, so they are certainly the larger style filters and not the filters we would normally put on our SR20's. With that being said, the filters being tested are within the same series/size range (all for the same truck), so the findings should be accurate enough to compare the different manufacturers.
Oil filter comparison Study.
Study final results and filter ratings.
Here are the top ten and bottom five filters, as rated by this study. The commonly referred to as
better filters are mostly at the top of the heap with a couple of surprises mixed in.

I don't think that any one particular oil filter study can definitively answer the question of which filter is the best. When comparing different factors and while under different test conditions, the variables will always change the final results. Having said that, the usual suspects more often than not are at the top of the pile.
