There should be a very small part number on them on the side (might have 2 different numbers on each side). Try googling them and see what turns up. Aftermarket injectors might come in different colors. But from what I saw when checking into it, many try to stick to ford colors. The colors might change based on model (ev*), but we should be EV6.
So likely they are 24 lb injectors that were replaced with aftermarket. I believe Bosche was the original maker.
Here is a good link on mustang injectors.
