First, if you are aware of a particularly good oil filter of any make, I am sure we would all like to know about it and your reasons for recommending it.
Second, I've heard that some Mazda owners use Mazda brand oil filters. Mazda parts suppliers show two oil filters for the CX-5, but provide no other information than that shown below. So, which should we use?

CARTRIDGE, OIL FILTER
Part Number:
PY8W-14-302
Alternate Part Number(s):
1WPY-14-302, PY8W14302
or
CARTRIDGE, OIL FILTER
Part Number:
PE01-14-302B
Alternate Part Number(s):
1WPE-14-302, PE01-14-302, PE0114302B

Third, in the past I found an oil filter that was not specified for, but did fit my Toyota, and I used it because it was larger than the specified filter. My logic was that more filter surface was better. Could that approach be used by the Mazda owner looking for a high-flow oil filter that is not Mazda branded?

 

I use the Mazda 1WPY-14-302 oil filter in my 2021 CX-5 Turbo. N/A models use the 1WPE-14-302. The primary reason that I use OEM filters is because the aftermarket filters do not specify a different filter for turbo and N/A models which seems wrong to me. I order the filters online for about $9 a piece.

 

Oil type and oil filter has been hashed out and the topic is already well expressed on server threads. So, to make it is....All the filters below have shown to ALL work equally well and not one outstandingly better and this is through OIL analysis changing the filter between 3-5 k miles.
If you are a die-hard GOTTA USE OEM ONLY then go to MAZDA online and using your exact vehicle information find the MAZDA oil filter to use on your engine.

Oberg
Mazda
Castrol
Mobil 1
FRAM
K&N
AMZOIL



Mazda often does not give its specification or and in many cases the use of different part numbers on the same engine has always been a MAZDA mystery? The filter I posted ALL have had Mazda filters and independently taken them apart and inspected them before adding their application guide update or in very rare cases an oil filter unique from the OEM.
As for going off reservation so to say and use an oil filter choice that fits the thread but not listed for the engine, it can be done as long as you can find all the important information about the engine and the type internal designs about the oil filter. Most what type of bypass (if any) they have.

The other to mention is IMHO all the claimed high mileage, better performing etc. in any oil filter line has also shown to be more or less a HYP even with the brands I use and have tested the filtration via oil analysis. While some may have the ability to go a couple of 10k miles before changes one would ask why would you do that in the first place? And as for the "who has the smallest micron filtration rate" while there is merit to this in the real world of normal engine use even in high performance engine use there has never been any evidence that it will increase the engine life past 300,000 + miles. It's all about advertising. This is the same regarding spark plugs. Don't get me started on them.

 

Most brands of oil filters will work fine as an alternative to Mazda filters, which are made my Denso.
I use Fram Ultra 7317.That the gold colored filter. That's the oversize for most Asian brand engines.
One of, if not the, best filtering filters available.
I have a magnetic drain plug for mine. **** maybe but they are cheap and cheap insurance.

My 2¢

 

Whipcitywrencher on YouTube has dissected all three or four Mazda filters, except for the media itself,
they are identical inside.

 

youtube is your supporting information. lol that video shows the very basic and only what a DIY can measure with the wrong tool. A veneer caliper to measure really and compare soft material ….lol this guy did a single measurement which is the incorrect way. You take several and average them out. see ultrasonic measuring gauges.
You should have just ended with your first response. At least that one I could at least support most of your info. Not the large filter which unless you are operating in an extremely dust air environment serves no logical reason to use.

on the magnet comment did you mean drain plug magnet or do u use a ring magnet on the bottom of you oil filter?


If you or any one would like to know the engineering way oil filter companies confirm their product line application to meet or exceed specification contact them.

And NO Mazda does not make available their engineering specifications for public access.
lastly no all Mazda oil filters are manufactured by Denso either

I wish members would verify before posting some information.

 

I have magnetic drain plug for my CX-5. I have small bar magnets but haven't
added them to any of my filters so far.

Of the 3 Mazda filters I'm familiar with, they are Denso made. IF there is one that isn't, I've
seen nothing about that filter.

 

if you are useing it on the oil filter it should be attached to the bottom. So bar shape are not the best .

just curious but did you filter box actually state denso?
mine only state the country or original Mazda Oil filter and I have several Mazda oil filters 4 different part numbers ?

 

The construction of the filter with the plastic(?) ring holding the media together is
fairly standard for Denso. Their filters for other Asian MFG's is similar except for ADBV on
some applications.
The PY8W-14-302A-MV is, it seems, the odd duck in Mazda filters. Metal end caps and uses
the nylon cage like Champ Labs filters.

 

Once again NOT sure where you are getting your information.
Please post where you obtained this information?
I know DENSO and Champ products very well and what you are posting is not accurate.
In a nutshell Denso manufactures and Champ in different countries and as such they like many manufactures of auto parts in the world DO NOT all use the same raw materials.

Maybe you should get a subscription to COUNTERMAN MAGAZINE and read it more often to get better information then the one you are using?
I read most every article way back when it uses to actually coma as a newspaper in the early 80's.
