These injector's will fit our M156 but will require an EV6 to EV14 harness in order to make them work with our cars. The injectors come in different flow rates as well.
I will be running Injector dynamics id1050x when I get to the point of e85, FIC is also a well known brand. And changing connector types is inevitable.
our injectors have a long nose. although the posted injectors may retain the same o-ring to o-ring length, you may not have enough penetration without the long nozzle which may have a chance of having your injector spray the walls of your intake runners versus running inline with intake charge. not something i'd chance on without test fitting and measuring depth. additionally different injector brands retain differing spray patterns. some shoot a mist, V pattern, or multiple spray patterns. with that in mind you will need to pair that with placement, and direction of spray to ensure the spray targets the correct area.
as far as the injector design you've posted, those are very common and you can find many injectors of that style very easily and for affordable prices. i've put together a few M156 to EV1 and EV6 adapter harness's that i'll make available in the near future for those who are interested.

I called and talked injector dynamics to get sizing and info on injectors. I noted ours were extended nozzle, I was told they found no noticeable difference when running standard nozzle injectors vs extended nozzle.
it's not just about that...its about spray pattern. injector dynamics only use ONE spray pattern so what they say may be true for their injectors. hence why i own a set of 1000cc ID injectors and they're revered as being the best on the market.
in regards to other injectors you cannot simply state the same without knowing what spray pattern your injector gives.
While I do agree about different spray patterns, I doubt the 1/4-3/8 extension is enough to make a difference. The final goal is fuel atomization and although it is possible to spray the walls, i doubt there will be any negligible difference when the fuel is spraying out at 45 psi+. Now there may be certain instances but id be willing to bet they are few and far between.
i disagree...sure maybe at 9000rpm when your aircharge is at X velocity, but what you run into is excess fuel usage at idle rpm. if you ever wonder why you have a idle stumble with your aftermarket injectors, it could be the spray pattern doesn't fit your intake runner design or length.
I have voiced this question with AFD and received the following response
According to Gary at AFD. The length of the nose does not matter. See below.
As it turns out FIC has done extensive research on this subject. They informed me that the Bosch injectors are long nose due to the design from Bosch, not that our manifolds require it (as some manifolds are built to require long nose injectors).
Other than the nose issue, the spray pattern remains the same as Mercedes as well as the length of the o ring and placement. I did mention to FIC that I would be supercharging the car. And my goal of 630WHP. They confirmed the 775cc to be the appropriate match. They do have long nose applications but those come in at 1200cc.
Based off of this information, I am going to go with the 775cc short nosed FIC injectors.
