yj 4.0 fuel injector upgrade

If you are gonna add more fuel, you will need more air. Larger injectors are usually added when boost is added or head work is done. I honestly don't know what kind of injector is in a YJ but if it doesn't have it already a 4 hole injector would help atomize the fuel better. I doubt this would make much of a real difference.

I forge the model but they are in dodge neons, there larger and fit
