Yeah! You can replace your stock injectors with one from a mid 90's dodge neon and will get a small increase in gas mileage. Supposedly it gives you more power as well but i cant tell you for sure since i haven't done this yet.
i did it a while ago and i feel it was well worth it, i havent measured the milage, but im sure it helped a bit. I noticed it had way better throttle response and it never stutters now. You want the injectors with 0280155703 on them. I believe they are in the 2.4L from 95-97.
I have a set of injectors from a neon numbers 703's for sale. I just swapped mine you can check my build thread in my sig to see. Super easy to do and while I didn't notice any gas mileage gain I have noticed better acceleration. Well worth it imo.
