your injectors. Injectors don't usually crap out all at once, but they can get clogged
up with dirt or old fuel if they have sat for a while.
And if you are running a stock blacktop with a factory ECU, you don't want to be
changing to a different capacity injector from the stock (OEM) injectors.

You will need to save the nose insulators from your existing injectors (rubber rings)
that seal the tip of the injector to the inlet manifold. Refurbished items from China
but don't let that put you off, they will work fine.
If your engine is stock with stock ignition and your ECU is a plain aluminum box with
four screws holding the cover on, that will be a factory unit.

I think that pic you posted is incorrect. There is no need for an o-ring
on the top as they are side feed injectors. And the ring at the bottom
is actually the top seal from a top feed injector !! There should be a nose
insulator there which is a sturdy square section ring. The nose insulator
is probably quite a common thing and may even be the same as the one
used on a stock bluetop injector. You should already have them.

bad information
On side feed injectors the two O-rings marked in red stop the fuel leaking
top and bottom. The insulator marked in green looks to actually be a fat O-ring
and it seals the injector against the manifold to stop vacuum leakage and also
insulates the nozzle against heat transfer. On top feed injectors the insulator
is usually a fat square-section O-ring.
This diagram indicates a second O-ring insulator at the top of the injector, and
this does not actually seem to happen on side feed injectors. On top feed injectors
there is always an O-ring close to the top to seal the injector to the fuel rail. On
the AE111 some injectors have a flat rubber "washer" on the top but others don't
have this ring. It does not actually seal but probably provides a bit of a cushion
for the steel injector retaining clamp to press down on.
You will have got this all figured out by now so just tidying up loose ends

Top & Bottom Insulators - 23291-75010
Upper O-Ring - 90301-17007
Lower O-Ring - 90301-14006
OR look for a set for the 1J injectors at the local parts store.
