I've used the little Nissan Gonher filters for my VQ35DE and they looked just fine. What interest would an OEM have in spec'ing an undersize filter that is used for virtually their whole line?
Don't tell me it's due to a cost savings conspiracy, that won't fly. I suspect the reason for use of a small filter is based on substantial research by engine designers and tribologists.
With all the customer complaints about winter engine noise and knocking on Nissan boards - which ALL GOES AWAY with a different somewhat larger filter in MY uses this spec was a mistake. There is such a thing as TOO SMALL. This is a hamster sized filter that fits well within the palm of your hand. Ruined my New Versa Note 2014 engine the first cold run. 14 Rogue was clanking in sub zero starts and warmup - went to the big Honda filter and all was well. Proof is in the pudding.
No disrespect to your observations, however...I very much doubt Nissan's issue with engine knock on some (very small %) of their VQ35DE's would be completely solved by a larger oil filter, if that were the case Nissan would not pay out for long block and short block warranty replacement repairs for these engines.
With modern engines, using the new oils, and adquate air filtering the small oil filter is well supported.
