Oil Filters
OMG I have sold likely thousand of oil filters, used them in a few products I have engineered and designed, several remote oil and oil cooling both for engine and transmission and every engine I built in my Performance engine machine shop the customer was given a quality oil filter most of the time was FRAM. And in some HIGH dollar race built engine assembled in a clean room and then run up for a break-in on and engine Dyno I never recorded any difference in oil pressure values base on oil filter size. LOL
As for capacity if you go so long or drive in the Arbian desert in a sand storm you are still likely to pop the oil by-pass in that large oil filter. LOL
You did get the pricing sort of accurate. Its all about a thrifty shopper. As I said I purchased a case or OEM Mazda filters by chance on line Ebay for as I recall 20 bucks shipped from Florida to my house here in California. Other wise and actually still do alternate between MAZD and a few different aftermarket oil filters on my Mazda. Oil analysis verifies NO oil filter was better then the other.

You can go find several of my Blackstone Oil lab analysis that confirms this and detailed pictures what brand and viscosity oil I use posted on this very forum LOL
Dude, you want to use the BIG oil filter fine but every time you claim its better a couple of us that know better are going to call you on that BS!

Oh and better go check the information about who ALL manufacture Mazda oil filters. The company actual name and where they are located.

While you are there check out who else they make oil filter for.

There are several sites that have extensively tested flow rates and holding capacity.
There are also sites that dissect different filters and compared the inner workings.
Center tubes with 'holes' flow better than louvers on average. The 'nylon' cage used by Champ Labs flows better still. Tribologists have also done testing on different types of construction.

Your assumption is incorrect, simple physics will tell you an oil pump will only move the amount of oil it was designed for.
Increasing or decreasing the size of the oil filter (volume or filtration material) will only affect the oil pressure and nothing more.
On Turbo will work. technically speaking if you have a Turbo and use the filter for none turbo which was the filter recommendation before a bean counter had their say in introducing a Turbo specific filter. LOL
Personally, finding and getting top brand no OEM oil filters is really a better choice overall. Castrol Fram, K&N to name a few.
DO NOT USE OVER SIZE FILTERS ON A MAZDA SKYACTIV 2.5 gasoline engine. We now know it can cause hidden issues. But that publication has not yet been released. watch for it in the near future

All three Mazda filters are the same size. Only real difference is filter media inside.
And even that is marginal. The efficiency of the media 'may' be better on the one for the Turbo engine. Two of the filters are made in different countries.

At least three oil filter companies Fram , K&N and Mobil one specifically tested the two filter from Mazda and found No difference that would nessitate needing a different oil filter for the Turbo engine. There is no technical information except a TSB to dealers to use specific part numbers but no empirical technical reason why .
Also depending on where the country the filter were made can also have varying filter media as long as they met the specific specifications set by Mazda or the filter company .
Actually the Prince engine in the BMW/MINI Turbo engine as well the early MCS Supercharged engines is smaller then the common on more then just Mazda engine oil filter.
I am new to the forum...last Mazda that I purchased was a new 626 in 1990 - but wife left in neutral and it rolled out of driveway across the street and hit a tree totaling the car
I bought a WIX filter planning to change oil after first 1000-miles in new Mazda 3 turbo but read some who said should only use Mazda turbo filter. From the comments (Callisto) I am hearing that my original plan was good and the WIX is just fine f/ the turbo and probably a better filter vs the Mazda OEM. Am I correct?
Ive always used Castrol synthetic and never change cars before 200K-miles so plan to do the same f/ the new Mazda.
Thanks!

Welcome to the forums.
Is your NEW Mazda a brand new car with a factory warranty in place on it? If so, I think that I would use the Mazda oil filter......that way, it is one less situation that the manufacturer could point to and say that the oil filter that you replaced the factory oil filter with......was inferior.......if you were to have an engine failure while the vehicle is still under warranty. When I change the oil and filter on a car that is still under a factory warranty, I always order the factory recommended oil filter to do the job. It is just a good idea to do so.

The Magnuson-Moss Warranty Act
Passed by Congress in 1975 - Section 102(c), 15 U.S.C. 2302(c), the Magnuson-Moss Warranty Act (MMWA) prevents manufacturers from using disclaimers on warranties in an unfair or misleading manner and allows an owner of a vehicle to choose what brand parts but protects them from any auto manufacturers disallowing an actual warranty claim based on the use of non OEM parts.
The none OEM parts must at least meet the specifications minimum . So most all nam brand oil and air filters all meet. And many exceed factory OEL specifications, and even quality.
