Hello all. I am selling sets of 6 4-port "upgrade" fuel injectors for '99+ XJs. Part number is 0 280 155 784. This is the most popular upgrade injector for a Jeep Cherokee 4.0. These are typically called the "Neon injectors" but they come from a wide range of Dodge/Chrysler cars and mini-vans.
The advantages of upgrading to these injectors is they use a 4-port fuel delivery as opposed to the single port of stock XJ injectors and this provides a more atomized fuel delivery which results in quicker starts, a smoother idle and better throttle response and acceleration.
I have completely disassembled, soaked, flushed and electronically tested these injectors. I have installed new micro-filters in the tops and put on new o-rings. I reuse the plastic pintle caps on the tips but clean then completely and make sure they have no cracks or chips.
I am asking $70 shipped per set. I can accept PayPal or a money order by mail. I am located in Maryland. If you have any questions about the upgrade or about injectors in general please do not hesitate to send me a PM. Although this is my first ad on this forum I have been selling them actively for years online.
Its a pretty simple swap out if you have even the most basic home mechanic skills and tools. I can do it in 15 minutes if I want but I've done it 50 times. There are a number of step-by-step threads online about it and 100's of threads on the injector upgrade in general. Here's a pretty long detailed thread off the Aussie OffRoad site..
hey buddy pm me your address..as of last time we spoke on the other site I was in a struggle now i caught up on the b.s. lol ill be able to send you some thing on or after the 17th is this ok?
Hello all. Just got back to this and found that for some reason I wasn't getting e-mail notifications when someone replied to my post or sent me a private message. I have some sets of 784's ready to go at this time if anyone is interested. Completely cleaned, reverse flushed, tested 2 ways and rebuilt with new o-rings and micro-filters in the tops. $70 shipped. I am in central Maryland.
Let me know when you are ready. I looked on Ebay and thought fuel rails would be cheap but they were all like $50+. I could probably dig up a good used one at the junkyard next weekend.
They are for a 4.0 I6 yes. The main reason for the fuel injector upgrade is that the Neon injectors are a 4 port or 4 hole design instead of the single port of stock injectors. This allows the fuel to be delivered in a more atomized manner which gives you a smoother burn. You get a smoother idle. Quicker starts and a better throttle response and acceleration.
I have a 95 with 4.0l. If I purchase these, when they arrive it's a direct swap? No cutting wires or anything? Just disconnect pull and then plug in and connect?
This thread is for 784 injectors which have the EV-6 electrical connection and will only be a direct swap for '99+ XJs. For earlier models you either need to use the 703 injectors or use the 784s with adapters. But no wires need be cut.

I have a 95 with a 02 ZJ motor. I have both wiring harnesses what injectors should I do? Are the pre or post 99 injectors better?
