Nothing wrong with the YZZD1 and YZZD3. Both well made oil filters.

I've cut a ton of toyota filters sayjac. You are right they are almost exactly the same in terms of size. Very smart design. The center tube on the thai filters easily slides out and you have a nice cartridge filter.
This is not an attempt to hijack this thread:
Gebo, can you take a picture of seam area of the YZZG2?
The reason for my question is that I speculate that Toyota completely specs this filter for Purolator to build. I believe this because about six years ago my Toyota dealers ceased carrying my beloved YZZG2s and wanted me to switch to the YZZD1s/D3s for my four cylinder Tacoma. As a result of my inability to locally source the G2s, I reached out to Purolator tech support and ultimately spoke to a real technical type.....yep, I know that probably doesn't happen today - but this was before the tearing issues. My question to them at the time was .. If I run your PureOne, am I exceeding the specs of the G2 as I know you manufacture that for Toyota as well. The rep went off as he said he didn't really know... And ultimately came back and responded in an affirmative.. At the time yellow speckled PureOne would exceed the Specs laid out by Toyota for the G2s. He went on to say that the filter material of the G2 exceeded that of the PurePlus L10241 but that the material of the PL10241 exceed both so it would be an excellent choice if I could find it... So I made the change for about a year as I could find the PureOne locally easily.
Based upon the above, I speculate that Toyota completely specs the G2 for Purolator and assuming that it is still built to the spec, I'd guess it probably doesn't tear if they are still using the Toyota spec'd filter material.
So, if all this is the case, I bet the G2 is still a good filter to use for the Toyota applications....
In the spirit of complete disclosure, I switched to WIX 51348 when the tearing issues started and have been happy.
Thoughts?
I am wondering if Purolator is still building that G2 to Toyota's standard .... Because if they are, they still should KNOW how to build a good filter... I just don't know that they are.

So, Gebo...
Being the BITOG person you are, did you look at the construction of the G2 in the seam area?
Did it have the wide spacing we have seen in the Purolators that are having issues?
If the concern is ultimately efficiency, the material color from your pics looks different than the D1/D3s and therefore may stIll be the original spec'd media from my discussion with Purolator years ago and NOT be the media from their recent Tearolator filters.
Sounds to me like you are struggling with the efficiency vs D1/D3 thing I did then too ... I suspect the G2s are not the low efficiency levels everyone points at today..... But there is no way to prove it, just speculation.
I ultimately made the WIX 51348 decision for exactly the reasons here and in your other thread...
(I wanted to stay Toyota filter. But there were just too many unknowns for my 2004 Tacoma with 206K miles... I felt comfortable with the WIX quality decision before they were bought... And continue to read every WIX thread today )
But, the wife's 4Runner still is using the rest of the 20004s I have

Do you know what the micron rating on that filter is?

Depending on just how irritated you are, you should take it up with Toyota. They are the one who authorize the contractors/makers of the all the topic filters. Like the Thai Denso made filters, the Puro made filter is made to Toyotas specifications, not M&H Puro.
As for their efficiency, there is one published data point that has been out there for the Thai filter. 'Fwiw', relatively speaking showed them not to be very efficient. Seen nothing for the Puro made Toyota, though I'd assume similar. As the OEM's generally make habit of keeping efficiency proprietary, unlikely you'll get any efficiency information from Toyota.

The 20004's were those Japan made Denso's that had the spongy media, correct?

Gebo,
Thanks for the trash dive.. I really do appreciate... And this is some good stuff.
So let's talk about what we are seeing and might know:
1) G2 media was and still might be better than the original PurePlus from Purolator. This is based upon my conversation with them a few years ago.
2) At least in my opinion, the seam area of the G2 and the presence of the metal crimp imply to me that this filter is not likely going to be a Tearolator - I also think the probable different media that Toyota spec'd at the time works in the favor of this.
3) I know we are both NOT happy to see the large center tube in the G2 that leads to less actual filter media. It seems based upon the pics that the depth of the pleats on the G2s might be half of the Thai filters.
4) Hard to tell but there seems to me to be 45 or so pleats on the D1/D3s... Can't really tell on the G2s. It appears that there might be more but I doubt that there are twice as many.
With all of this, a lot of my perspective is going to come down to the great unknown : How good is the media in the G2. My gut says the overall filter efficiency of the G2 still might be better than the quoted numbers we see in the Amsoil docs for the F1 family (and by association we place on the D1/D3). But I don't think there is any way to prove it.
Not trying to give advice, but if you really wanted to stay with a Toyota filter would it be a G2? Personally, I don't know. If I had to stay Toyota, I'd probably go G2.
I wanted a moderate level of efficiency - above the Amsoil claim - with some level of confidence, hence my decision to go WIX. Based upon what I see, I am still feeling ok with where I have ended up.
