Weight was a factor taken into consideration. While I have yet to weigh these two filters on a scale, the -20004 is heavier.
Glenn, I sent you an E-mail.

Regarding filter measurements. One very simple suggestion is simply weighing the filters, complete. Then weighing the filter media once the filters have been opened up. I have found through the years some amazing differences in filter construction, quality, just by comparing weight..

Michael,
What things are you planning onlooking at regarding filters? I was thinking along these lines for a project when I finshed my air filter study.

I posted this earlier in the Tundra Solutions forum in reply to "Toyota Oil Filter Part Number". I thought that I'd give this post it's own thread here in the I-force V8 section as I plan to expand this oil filter study. Anyways here's what I came up with so far:

There are two Toyota brand filters available for the 4.7 liter engine.
My engine still has the filter from the factory and it is a 90915-20004.
Also available for it is the 90915-YZZB5.
I bought both of these filters because I plan to do a unofficial oil filter construction study for the Tundra application. So far I can only offer external observations on these two filters. They are as follows:

The -20004 is about a 1/4 inch taller than the -YZZB5 and appears to have a metal end cap (looking thru the bottom hole.) The gasket and backflow valve are made of a orange rubber material. The filter media is high quality with it's pleats reinforced by plastic. Made in Japan. It cost $9.65 from a local dealer.

The -YZZB5 is shorter and appears to have a plastic grid reinforced paper end cap. It seems to have the same high quality media as the -20004. The gasket and backflow valve are made of a black rubber material. Made in Japan. This filter costs $4.91 from the local dealer.

Both of these filters backflow valves held pressure well when forced back onto their seats. However, when pressure was applied in the proper direction of flow, the -20004 valve opened with noticably less effort. Meaning that oil should flow easier in this filter. Nothing is really conclusive of this particular flow test as the filter was tested with compressed air and vacuum pump while screwed on a pipe nipple.
I plan to have our machine shop cut these filters open as soon as I acquire other brands for the Tundra application
