I have a 92 as well did you use. Specialty tool to disconnect the hoses from your fuel rail or were you able to manage without it I just got 4 injectors for free I just need 2 more and I could throw them in my xj..

 

My 92 only had a clip holding the electrical plugs on the injectors, and then another clip holding the injector to the fuel rail, it was pretty easy, but when you reinstall the square clips(ones that hold the electrical plugs onto the injectors) put them on the electrical clip before you plug everything back into your engine, or it's a horrible pain getting the last 3 on there

 

I wanted to post my results from doing the injector mod so future members could see my results.

In my test - I drove around 1000 miles before to test my mpg and 1000 after the install to see if anything changed. I used the 702 model which is the European equivalent to the popular 703's most use here. My XJ has 265/65/17's with 3" lift. Sidebar - I used the difference in tire size calculation to adjust my mpg since the tire diameter difference throws off the speedo and the trip meter.

My results - I lost about a 1/2 mpg going from the factory injectors to the 702's. This is totally the opposite of what I thought would happen. The stock injectors seem to be more efficient then the 702 injectors.

 

Uh oh. The only accurate part of that is that the 702s come in European cars! A lot of people make this mistake because there is a misprint on the Bosch injector data sheet that has the 702 and 703 injector being exactly the same. Someone who sells upgrade Jeep injectors made an upgrade sheet which is now spread all over Cherokee/Jeep forums and thus this info gets seen a lot. The 702s actually are the same as the Ford "yellow stick" ones and put out a lot less fuel per minute than the 703 or stock XJ injectors. If anyone doubts this just grab an ohm meter and test a 702 and a 703. You will see the difference and that the 702 is reading the same as the Fords. If you go to a website like WitchHunter you will see the actual data for them.

 

I'm sorry about this. But I have a 2001 4.0L from what I'm reading I need injectors from a ford? 5.0? I read a couple different threds and I just want to make sure before I buy

 

Back on the first page or two, there's a table that shows what you need.

Ah, found it. This should do it for ya!

Has anyone tried these? They appear to be the newer style connectors w/ adapters. Seems like a pretty good deal compared to the other reman injectors available.

http://www.ebay.com/itm/251223462199?

 

Bosch makes a lot of injectors. The seller appears to have turned all of the bodies so that the part number is not visible, and has not mentioned the real part number in the ad. Would not buy for that reason.

The "784" injectors are Bosch 0280155784 and identical to the 0280155703s, just with a USCAR (99+) connector instead of JETRONIC (98-).

 

Thanks Salad, i sent the seller a message asking the Bosch part number.

 

Programbo on here can likely give you a deal than that by the way (probably better). Drop him a line!

 

eBay vendor said that the injectors are: XF2E
He also gave a link: http://www.fiveomotorsport.com/bosch...injectors-xf2e

 

I run those. XF2E-C4B. Only ones I could find in my local JY that would fit my '99. That's because I was cheap. If you're buying off of eBay or another vendor there's absolutely no reason to not buy the correct injectors in the first place that have the appropriate connector.

 

As far as I know the 703's are amongst the good "Plug-&-play" options for 91 to 99. Not sure weather the later have Ev1 connectors or not. Here's some Bosch stuff> http://www.polog40.co.uk/article_injector_table.php

The 280 155 746 are **** for 87-89 Renix jeeps. (not the 91 on, HO/OBD Jeeps). The 703's will work fine, just they will run rich while in "default" before it warms up, and running rich won't help it warm up.

 

Those are a lower poundage injector than stock XJ ones just with a 4 hole spray. They are basically the same poundage as the Ford "yellow stick" ones. If you want to go with a slightly lower # one but get a 4 hole spray this is my favorite substitution:

What are these? I tried running ford 19s on my 88' and they gave me a smooth idle but bad mpg
