Injector Question!
I have a 2000 xj 4.0 and the injectors are all cracked, have no idea how theyre not leaking, anyway i was reading that most of the chrysler 2.4L injectors will work the greenish ones 789s. well i found a set of injectors at my work but theyre blue colored kind of and out of an 03 or 04 dodge caravan with dohc thats a 2.4 will those work if i find 6? If they wont work, does anyone have any part numbers of the 789 or 784 injectors? Because we have boxes of random injectors but im not sure which ones i can use. All i know is there were no stock cherokee ones for my year, and i need to change mine asap, so if i have them id like to upgrade. Thanks guys.

Complete Bosch part number for the Neons is 0280 155 784 or you can run ones out of a liberty for a better flow match. Bosch # on metal sleeve is 8021x. On mine, the x is a 3. I have a set for sale $90 shipped.

When you run the stock injectors, they develop leaks and smell like gas
When you smell gas under your hood, you buy a fire extinguisher for your Jeep.

Don't let people think you are a psycho, ditch the stock injectors and avoid fuel leaks and car fires. :-)

I'm curious about this. Is there a difference in the pulse length or intervals? It seems if one was putting out 50% more per pulse then after a minute you'd have the stock ones at say 225 cc/min and the Neons at 340 cc/min.

PM me for more details since I can not follow up on all the threads I reply to.
