Ed, the wix racing filter does filter more dirt by means of a glass-enhanced media.Also the can structure is stronger. Yes I know napa filters are made by wix to napa specs. Good filter.But I don't mind spending a couple bucks more to help protect a 15k motor.

I switched from Wix Racing filters that have a 60 micron rating,to Moroso,that are rated at 27.I like a bit better filtration.Just my thinking,probably worried over nothing.

There are no free rides....

If you want more filtration you end up with less flow (pressure)...

If flow cannot keep up with the internal engine leakage the motor will seize up no matter what your oil pressure is......unless the pressure is monitored at the last location of oil flow....

A tight clearance engine needs less oil flow than a loose clearance engine...

If you monitor oil pressure in the area of the filter it is the highest in the system....

We should be concerned about the lowest oil pressure within the system....

Just something to think about and most of all never forget "The law of unintended consequences"

PS:

I almost forgot the MOST important thing to remember about oil filters is to get the metallic debris out before it gets to the oil pump and filter..

We have been doing this stuff for so long that we take a lot of the things we do for granted..

Go out and buy a bunch of 1/2" square magnets and position them inside the engine so that the oil draining back to the pan has to flow over and around the magnets.

You can place them in the heads, the valley or even in the pan....

The pan part also works for transmissions, both stick & automatic..

Put a couple in see how much metallic debris sticks to the magnets....

I've been to the wix factory and can assure you,
Napa and Wix filters are the same filters, different
packaging. I even got to make my own. The filters
made to some other one's specs are for the OE.

Valvoline Packages NAPA Motor Oil as well

I use K&N filters because of contingency and Steve Williams.

I was concerned about flow. Before I made the switch,I consulted with my engine builder and Moroso.I change the oil and filter every 35 runs and cut the filter open.After one year,no issues.
