i dont mean to jack the thread...but does anybody know if the #703 injector from the 95-97 2.4L is a plug and play for a 97 xj? or should i be taking the connectors from the 2.4 as well as the injector?

side note...has anyone run into the issue of the ECU having to relearn the timing/duration of injection because of the differences in the two injectors? or are they rated the same, just the neon has more orifices?

I have a 98 and they are direct plug and play for me. Should be for you as well.

The 2.4 and Neon 2.0 injectors are the same.

Not sure....at some point 99 or 00 Jeep switched the injector connector from square plug to round plug. The 703's are square.

Ok, the last tank of fuel averaged out to 17.8 MPG. Before the swap I averaged 15MPG, so a 2.8MPG gain is huge for a simple injector swap!

i did the 703 swap to find out that on my 2000 xj they r to short so i got 784 out of mid 90's stratus and they give better fuel mileage and response, revs up alot faster with no hesitation. they are direct plug and play with 4 hole instead of 1

ok good to know.. i figured it would work fine. since the 2.5 is pretty much the same as the 4.0 just with 2 less cylinders.. so i figured the bore and stroke / injectors would be the same.. correct me if im wrong but isnt the reason why they injectors increase mpg / throttle response etc is due to the spray pattern right? cause ive read that our stock injectors have a one hole spray vs the neon 4 hole spray? thanxs for all the great input guys

ps i was born in manassas va too so good to see a fellow virginian... except now im a west virginian lol
