yeah, use dodge neon injectors. Not sure the flow rating I just know 5.0 mustang injectors have the closest flow rate to stock cherokee and have a wetter better nozzle set-up.

So mustang 5.0L injectors have the same electrical connector as the Renix (H.O.) engines, correct? Cause I bought some, and of course they wouldnt work in my 99XJ. Nobody seems to give good details about things like that on forums. I would have switched the electrical connectors, but I think the depth of the part that goes inside the engine makes it impossible to use them?

Oh well, guess I will buy some of the neon injectors, unless someone knows something about using the 5.0L injectors in the newer XJ's. Thanks!

both thread mentioned... tell you this... they will work in renix and ever up to like 97ish or so... youll need a connector you can pick up that fits the plug and then the injector on te other end... i didnt have this problem but it has been covered so im sure if u find who talked about it and PM them then they will help you out little more...

I was in the same boat as you... No one had any real info on 99+ injectors. If I asked and was told to search, which yielded crap. Sorry but all the injector threads lack concrete 99+ information. Buying EV6 to EV1 connectors is stupid and expensive.

I used ford part #0280155917. 19#, 4 hole all Orange. There is a sets on ebay all the time. Hope this helps...

99-01 Cherokee
Stock Jeep injector:
22.5lb/hr@49psi (236cc/min@337KPa)
or 21.4#=225cc @ 43.5PSI
Owners have used Ford 19# XF2E-C4B=204cc@43.5PSI injectors with success, they have the same specification as the #19 ford 280155710 (i.e. 4 hole ev6 style with a nominal working pressure of 39PSI) just with a UScar electrical connector and take clipnuts.



More flow (much closer to the stock injector flow rate than the ford XF2E-C4B) is provided by Bosch #0280155784 (22.5#=238cc@43.5psi), which are the same as the older Neon injectors 0280155703, but with a uscar electrical connector.

Chrysler part # 4669938 from;
DODGE CARAVAN (1998 - 2000)
DODGE NEON (1998 - 1999)
DODGE STRATUS (1998 - 2000)

Another alternative for the stock 99-up 4.0L is the (22.8#=240cc @ 43.5psi) Ford XR3Z 9F593 A4B / XR3E 9F593 A4B (MOTORCRAFT #CM-4956 )which is the newest design and offer even better performance.

This injector has a single hole and looks disappointingly similar to the stock 99-'01 injector .
The main method for increasing atomization in the ev6 injectors was by increasing holes number and reducing each hole size. One can't add holes and reduce size indefinitely, so a new approach was needed when regulations became more strict.

The newer design is not relaying on number of holes, it's a completely different approach with the difference in the internal orifice which allows far better atomization. This allows even better ability to work on variable pressure, as with most newer cars the pressure is computer controlled.
This, in turn, gives more accurate fuel mixture at any given pressure.

You can check the two in your fuel rail, when out, and compare the spray pattern, with the newer the fuel is like a mist.


if even more flow is required the “1999 only” Taurus/Sable injectors, 0280155849 can be used.


This EV6 injector will flow 265cc/min @ 43.5 PSI, same as the FMS M9593-A302(24 lb) but with USCAR connector so the original injector clips on the loom will plug straight on..
