Stock OEM LT4 Camaro ZL1 injector P/N
Any idea what our car comes with stock, looking to replace one.
Or is there another P/N I'm missing, there are a million of them Thanks

I hate to say it, but I wonder if you have to pull one of yours and get the number off it. I thought I remember reading about them being matched sets by part number?

I can see 12668396 on the black portion of the body of the injector using borescope, looks like a valid part #. Doesn't look like they are available any longer.
Following what I can tell it was replaced by 12703611, and then 12710478. At least all 3 indicate they are nominal flow.

If you replace one, it has to match the other 7 injectors as far as flow rate is concerned.
If you do all 8 then just make sure they are all of the same flow rate / part#. The part numbers have been replaced a bunch of times over that past few years. There is already a thread on this but you gotta search to find it. |

you have to pull one or you may be able to use a scope. if its high, low, or nominal just get the same flowing injector even if the part number had changed. But remember the LT1 has the same option so hi, low, and nominal I've seen some people get burned because they have high flow lt1 thinking there LT4 because they just see Hi-flow!
I got lucky and after I researched every possible LT4 injectors i called classic parts internet division gave them all the numbers and found that they had some of the LT4 older part numbers for 60 each vs the 85 plus that you will see once you start researching. I made a thread about 8 mos ago and listed all the numbers. It didn't matter to me on the flow since I was tuned I just put all new 8 injectors and matt retuned for no N/C i didn't feel like pulling the blower again its not hard just time consuming and messy with the IC coolant so if you can find a good deal do all 8 especially if your paying a shop the labor could be close to 400.
