Question About 2006 LX470 Injector O rings kit. (1 Viewer)

[Kamran Khan]

I have searched partsouq given the VIN number of my car, part number for the injector is 2320950080, but when I try to buy the O rings set for the injectors, it only shows two type of O rings available from Toyota, while Mahle kit has three O rings going on one injector.
OEM kit has only vibration Insulator, part number 2329141010 and O ring that goes on the top of the injector, part number 9030107037. Couple years ago I used this third 0 ring that pointed the arrow to in the picture from Mahle, few days ago when I removed the intake manifold and inspected the injectors, that third O ring that comes in Mahle kit was completely cracked and was about to disintegrate.
I am confused if that third O in Mahle kit is necessary then how come the factory catalogue doesn't show this?

Answering my own question in case it helps someone in the future: After checking the factory service manual on TIS, reviewing the Partsouq catalog, and comparing it to older model Cruisers, I found that these grommets are not needed for fuel injectors with part number 23209-50080. So, if your car is a 2006 or 2007, you don’t need those grommets—nor does the parts catalog show them.
In short, if your car’s fuel injector part number is 23209-50080, you don’t need the grommets I pointed to with the arrow in the picture above.
By the way, the part number for the grommet is 90480-13005. These grommets are only required for injectors with part number 23209-50040.

When I did mine on my 06 a few years back I kept a photo of the items for the injectors, and don’t remember doing any grommets.

Picked this up from the local Toyota dealer.
