Looking for fuel injector upgrade for 99 XJ I6

XJ gurus,

Please tell me which after market fuel injector I can swap in directly in my 99 XJ I6. Where I can find it at reasonable price?

Not sure which one on a 99 but try http://www.fiveomotorsport.com/

I'm actually wondering the same thing. I am more curious which vehicles at the junk years would have the correct injectors? I would prefer to do this upgrade for $5 from the local junkyard, and take my chances with the injectors working.

I pulled some from a 2000 Ford Taurus, P/N YF1E-G4B, but it looks as though they may be too big.

Anyone know which vehicles to look for?

5.0 mustang... should be ford orange tops rated at 19lbs.

they are in my stroker, should be sufficient enough.

Yes.. orange or yellow top 5.0L injectors.

I just got a set of orange tops from Performance Auto Injectors for less than $100 deliverd to my door, rebuilt and flow matched. O-rings were included and installed on the injectors. www.painjection.com. Great tech support , too.

Thanks for the input, but I don't think orange/yellow top will work on 99+ XJs. 99+ XJ's injector operates at 49 PSI.

Actually, deisenba presents my question more concisely, I am also interested in pulling injectors from junnkyard by myself or get a parts number to look at ebays.

No matter which injectors you scrounge, run a can of BG44K through the tank. It will clean them like new. Don't even bother with the cheap injector cleaners, they just don't stack up.

You want 19# EV6, solid orange. Pn# 0280155917. It will flow over 23# @ 49psi.

Maybe we can add that to the "list"

Best response! One of the most important points often overlooked is the flow matched.

This is exactly what we were looking for. Not just an opinion, but also an actual part number. After a quick internet search, some of the junk yard vehicles these can be found on are...00-04 Super Duty 6.8L 00-04 Econoline 00-04 Excursion. Sell online at misc places for $400/set. Just bought 10 for $20 shipped on ebay. Out of those 10, I am sure there are 6 good ones. Will report back my findings in a few weeks.

I don't know my fuel injector cleaners, but I do know from reading many of your posts that you know your Jeeps quite well. I will be running a bottle of BG44K through the Jeep once the injectors are in.

I will keep you posted. I might even make a junk yard run and pick up 2 more and sell you a set of six for $10. I know on my 89 XJ this was by far the best mod I did. It totally restored all the low end power, made the idle very smooth and even bumped up the mileage a little.

I installed them 2 days ago. They run great after a few start cycles. Looky here:

They are on ebay all the time... for $50/set or less shipped. One guy puts in new pintle caps and o-rings.

second on the bg44k injector cleaner
stuff works wonders

Doubt it would have done anything on 4xSanta's problem back a year or two ago in Moab. He had rusty crap packed in the #5 and #6 injectors. Surprisingly we managed to clean it all out and still runs fine.

I installed mine about 3 weeks or so ago. Not nearly the difference that I saw on the renix when I did it, but still a noticeable change. The idle is smoother, and low end is also smoother. I wouldn't say that it feels like there is any power gain, but $20 for it was definitely worth it.

It did take much longer to start than I thought it would take. Once it started, it ran like c r a p. Once running I had to turn it on and off about 3-4 times before the computer figured it out, then it ran very smooth. Took about .25 miles of driving to get the check engine light to turn off.

I can't comment on fuel economy yet. Only driven about 100 miles or so. It might take another couple months to burn through the rest of this tank and to make it through another. Once I have some fuel economy readings I'll comment here again.

So, if I have these: '96-'99 53030778 Grey 49psi 23.2lb/hr
I shouldn't worry about upgrading to the 19#EV6? It sounds like they run about the same.
