That filter is a Japan filter. It is WAY better in quality and construction. I observed the same with my Highlander. Yu are observant. Not even the dealer understood my concern.
I had an issue with my 06 H/l initially and was given a case of "D1's" USA replacements for free on the house. I used one initially, because the -20003 Japan filter is nowhere to be found except in Japan. I
I saved and cut open the "20003" filter and compared it to the "D1" and the D1 is way inferior in construction AND design. It is slightly taller as well(20003) with slightly more capacity. The two filters have different filter media. A COMPLETLY different filter all together.
I searched for the "20003" till I dropped.
Result: The "20003 JDM" Japan version crosses over to a TRD (Toyota racing Developement Filter).
It is available only through TRD sites and some Dealers will order it. Any dealer can get it if yu just supply the Part Number.
It is very expensive. I seen $ 25.00 as the average price. It is colored Red/TRD labled. It is a high pressure/high flow with stronger can to resist rupturing during hard engine use.
I say this filter was appropriate for the initial break-in oil but why can't we continue using it as a standard replacement? Not fair to Toyota owners!!!!
FYI, I am currently using a K&N #HP-1002.
Mobil 1 filter is my second choice, followed by the PURE One.
I would ONLY use these three types in any of my Toyota vehicles.
Bosch filter is not a great filter...just on par with a FRAM ....also not great.
But, I really would like the "20003" Japan Filter or TRD equivilent if I could get it for under $ 14.00. Then I would get a case of 10 and just stock up.
I've been unable to though. I use only MOBIL 1 Oil 5w30 and only want a premium quality filter as well!
There have been numerous studies on all the oil filters out there.
Google this and yu will see what I mean.
I don't like the anti-drainback valve and pressure relief design of the Taiwan D1 replacements. These are $3.00 filters if purchased by case at dealer.
I addressed my concern over this issue with Toyota. All they say is that the D1 filter meets specs. I say it is subpar to the Factory Installed "20003" filter!
Yu are very observant, and never figured anyone else knew what I was taking about.
Bosch is not a great filter and I would use the O/E (D1) instead if yu don't have a choice.
