Remember though that even though the Mazda B6Y114302A and B6Y114302B oil filters are small, they have almost twice the internal filter element and is a better quality element that a Fram or Wix that is double the size has.
Plus the anti-drain back works right (again unlike some other brands out there).
From the Team Miata site (which the Miata uses the same filter as the FB/FC/FD uses):

When it comes to oil filers you have a lot of choices.
The Mazda Stock Filter
Purolator - L14622
FRAM - PH6607
AC Delco - PF1237
A while back we asked ourselves - "What filter is best filter for our Miatas?"
We decided to check out some of the filters the old fashion way - by cutting them open.
Here is what we found.
In the group, the Mazda filer was the smallest - so we figured that is would have the least amount of surface filtering area. Boy were we wrong.
The Mazda filer had almost three times the amount of filtering area as compared to the biggest filter - the FRAM.
The Mazda filter had about twice as much as the Purolator and the AC Delco.
At the time the Mazda and the FRAM were the only two to have check valves (none of the others available now - including the Fram - have check valves of any sort).
So - who needs a check valve anyway? Well what the check valve does it force the filter to work as a filter. It also keeps the filter from back flushing which can happen with any sudden drop in oil pressure. The others, if they get a little clogged, or with a sudden drop in oil pressure, the filter stops filtering and is bypassed. The check valve in the Mazda filter prevents this from happening.
So - if you are out looking for a better filter - it probably hasn't been made yet. Someone would have to work pretty had to make a better filter then the Mazda filter - and they would have to make a hell of a lot of them to even come close to the price Mazda sells theirs for.
So instead of worry about filters - go for a drive.

btw there are three different types of mazda filters out there for FCs.
JDM model (best according to some, mazdatrix sells them)
US spec, it is black... ithink that is the one the miata article is testing.
Canadian spec, it is blue, made in canada. I'm sometimes skeptical about it... but at 5 bucks a filter and me changing it every 1000 miles who cares.

hmmm filters
From a quote in this thread:
When it comes to oil filers you have a lot of choices.
The Mazda Stock Filter
Purolator - L14622
FRAM - PH6607
AC Delco - PF1237
The AC Delco I use has a different number
PF1127C
And as far I can tell the ones sold by Mazda Canada are made for them by Fram...
Here is a link to an interesting article that helps flush out the information and differences about various filters, no RX7 type filter was tested but by reading this you can see that all filters are not created equal! From this test I found that the AC Delco had a relatively large filter area, especially considering the size of the cannister.

This is sort of hersay, but along the lines of what Cheers was saying - Mazda screws us for money for every single part. What are the chances they are selling something equivilant or better than everyone else at a lower price?
It would seem to me that as long as you're not plugging up the filter, the single pass filtering would be the most important number.
