Realwing, didn't you post these on another Acura/Honda forum also?? I could swear I've seen these identical pictures on an Acura MDX forum. -Joe
I have to admit that the Toyota design looks strange and restrictive! I have five 90915-YZZA1 filters sitting in my pole barn and one on the car right now. You can tell that someone went to an awful lot of trouble to design this oil filter. You have to wounder why they deviated so far from industry accepted filter designs? It is not like Toyota to reinvent the wheel. Toyota normaly sticks to what has been proven to work unless they have good reason to redesign. I have to admit that I am not happy with the use of cardboard. I wanted the ones made in Japn with the steel ends and verticle sloted plastic center tube. I can say that I have no start up noise not even after an oil change. I also do not get the idiot light warning.It will be interesting to see UOA before winter comes!
You guys MADE me do it,
so I figured this was the best place.
Internal views of the Toyota filter for their new V8's:
I think you will agree this is a unique filter.
Nice back plate with a unique seal. This thing is hard to get off the engine once it's on.
A side view of the combination ADBV and bypass, partially removed from the nylon support:
End view of the media:
Filter media in the can. I propped it up with a rock. Plenty of room for flow.
Back plate and media/valve assembly. You can see where the seal seats on the plate. The combination valve makes for a very short oil bypass path, prevents the media from being exposed to bypass pressures and makes for a less expensive manufacture.
The filter media is 1/8 inch thick, yet I can easily blow through it. It seems to be some tough stuff, and hard to pull off the nylon cage. I had to cut & scrape to get to the cage for these pics. The top of the cage is also filter media.
The dark stripe across the media is the ruler shadow.
I hope you guys like these. When I told the parts guy that I was going to cut the filter open, he told me he would give me another if I brought the open one back.
I might do the V6 filter next, and if I do I'll post those as well.

can u please do the 20004 filter...i been wondering about that for my friends tacoma. i would like to see. interesting he said bring the open one back...maybe u can get another one as well =). thank you for ur effort and time for these pictures.
that toyota filter looks aewsome. to me it seems like a multipule stage filter.
the shallow area provide good oil flow and is what do most of the filtering. the thicker areas slow the oil speed down and filter it better(as it goes through more physical filter media), so it is sort of a built in bypass filter inside the filter.
(kind of like a trasko works)
thats what i make of it anyways. what do you guys think?

Denso . You can see it on the side in the first picture.
do they make the new style for a 94 camry 4 cyl?
aww man, i meant i needed the ****** 20003 filter for the toyota tacoma 2003.
Very interesting and I am shamed that I was not aware of this design ! I will really enjoy seeing used oil analysis and feedback from users of this filter. Somebody at TOYOTA wants oil moving uninterrupted and filtering simultaneously.
Thanks smoothflyer for contributing !
Thanks RussellA for waking me up !!

Do both the Toyota 20004 and the Lexus V-8 filter shown have 3/4"x16 threads? If so, they'd fit my Neon, which takes the same filter as a 95 Camry V-6. Both look very interesting, especially the Lexus version with the "missing ribs".
Can anyone direct me to a reliable, relatively low cost online source for these filters? I'd be willing to try a few, along with my (so far) untouched stock of AC Ultraguard Golds.
*Thanks* for your first-class work done here. Excellent close-up photography, great information, and a real sacrifice of $$ on your part.

The 90915-YZZB5 filter as shown has the same mounting threads and gasket base size as the Fram PH-8A, Motorcraft FL1-A, etc. I didn't measure the size 'cause I already knew it fit my Toyota truck V6.
I get these filters from the local stealership, without a discount, for about $6.50 each, including tax.

Thanks, smoothflyer. I've since cross-ref'd the #'s at the Wix site, & they gave me the rec'd Wix for my Neon, #51348.
Looks like If I want to try them, best bet is just to go to the Toyota stealership. The YZZB5 looks especially interesting, with the 3 "missing" filtration ribs.
S. Hughes,
Check in the favorite links section for an online discount dealer that I posted. Best prices I've found so far.
This info was posted by "Pappy" on a Toyota 4x4 board I frequent. It gives some history on Toyota filters for trucks:
"There have been several filters used on the R-series motors over the years. The original filter, 15601-44011, was available up until the late 80's. It was a rather large filter, similar in size to the Fram PH8A. In the fall of 1988 a compact filter was introduced, 90915-03002. This, like the previous, was a Denso/Japan filter and later superseded the 15601-44011 filter (though a website sent to me today suggests it's still available, need to check). Sometime in the 90's 90915-03002 was superseded by the Puralator/USA filter we find available today, 08922-02011, at least in the USA. I say that because outside the USA another filter is used, 90915-YZZB9, another Denso/Japan filter. Unlike the USA filter which has a pleated paper element the YZZB9 filter has a resin element. Also used on the RET motors in 1986-87 was filter 15600-25010. This filter was the same diameter as the 15601-44011 filter, but shorter. Why? Because the RET motors have an oil cooler that sits under the filter and apparently the additional height caused a problem. I believe this filter is still available.
Ok, lets play in the mud. The original Land Cruiser filter used on F-series motors, which is still available, is 15600-41010. This is a huge filter that happens to fit 20/22R-series motors (NOT 2RZ or 3RZ Taco motors). This filter was somewhat superseded by a compact filter with, I believe, the introduction of the Tundra/LC V8 motors, 90915-YZZB5 (though every LC owner I know refuses to run this puny filter on their trucks). This filter is just a tad larger than the YZZB9 Taco filter. Both of these are Denso/Japan resin filters. Recently another filter has hit the USA. As best as I can tell it's used, again, overseas. It's 90915-20004. I don't feel rich enough right now to cut this filter open and compare to my YZZB5, but I can tell you some differences.
First, it's about the same diameter as the YZZB5, but .15" taller. Looking inside I saw something I didn't see in the YZZB5 filter. That's a pressure bypass valve! This valve opens in the event that the filter becomes too clogged to pass oil through the element. It's also used when cold oil has a problem passing through the element. Not really a problem in the USA where most folks are anal about changing oil, drive mostly on pavement, and run thinner oils. But always a nice thing to have for those of us that get dirty occasionally. I know Wix filters have it, but need to check the USA mini-truck filter. According to Toyota propaganda, all of their filters have the bypass valve, yet I can tell you without doubt the YZZB5 does not and have the pics to prove it. Note that I haven't checked the YZZB9 Taco filter.
So, what is the debate? The question is, should we all be happy with the paper element, made in the USA, filter? Or should we look for better options within the Toyota family? And then, which size? Obviously, running a larger filter will allow us to run more oil in the motor. That's good. It also would give us more filter media to protect our motors. That's good too. But is it really necessary when we run synthetic oils with 5K oil changes (or dino on 3K). Is there really an advantage? I really can't answer that, but frankly I would rather give my motors the best possibly protection I can. Over kill? Over engineering? Ya, probably, but so what!
I've been running the YZZB9 Taco filter for some time now, largely because I feel the USA filter is adequate. I just ran out so I can't check for the bypass valve, so I need to do that.
My personal feeling right now is the 90915-20004 LC filter is the best all-round option. Between this filter's slightly larger size, the resin element, and the bypass valve, I think it's the best on the Toyota shelf. But you are going to pay dearly as it lists at $9.62. The YZZB5 filter lists at $5.41. The USA mini-truck filter lists at $4.91 while the Denso mini is $7.34. For comparison the giant LC filter is $12.33 (ouch). Obviously, if you buy from a discount dealer like many of us do you can do better, but it still can sting. All prices are the "last I checked.""
Hope its helpful.

I use a hacksaw, which as others have pointed out leaves it contaminated with metal shavings. I have seen references to a lathe and filter cutters. I am thinking of trying unrolling the crimp at the base with wire cutters. There was a thread back in March, "Best oil filter for under $6" that I think had several posts on this.
The more time I spend here, the more I see suggesting that any cheap filter or even a Fram is good enough for short change intervals. At Wally's I get about 3 times as much filter area per dollar in the ST for my truck as the Fram.
