Finally got around to putting in the four hole injectors. Jeep runs much better no more long cranks when the engines hot. Thanks for a good product at a reasonable price.
I just put a set of your 12 port injectors in my 91 XJ and I can't believe the difference! Way more power, much better and smoother running motor. I'm honestly shocked at the difference!
Thanks for the high quality vid and your KSuspension products in general. Just a side note-- there's a Schrader valve (like the ones on tires) on the fuel rail; any time I'm working on fuel line, etc. I like to take the cap off and push the valve stem in to alleviate fuel line pressure. This coupled with gas cap removal will ensure there's absolutely no pressure in the fuel line.
I seen many videos. This is by far the best one for this job sir. Good job man. I always try n make videos but I have add. So I can't focus enough to make a point in my videos.
This is an amazing video. I bought a set of 4 ports from you for my 1992 about a year ago and am finally getting around to installing them, as we were sorting out a transmission issue. Thanks you for all of the wonderful information.
I agree with others to the excellent quality of the video. I received a set that had a bad injector, called and KSuspension was very apolgetic and got a new set immediately to me. As others have stated service and follow-up are outstanding. No reservations in rcommending KSuspension to others.
My jeep doesn't even necessarily need new fuel injectors, but now I want to replace them 😆 Sweet dipped cylinder head cover too! Thanks for the easy, comprehensible video!
Just make sure you have the correct injectors for your pigtail or you will be splicing each one. I have a 97 Cherokee sport with a 95 engine and got a bunch of parts off an 01. The 01 injectors are a different connector. Also there are some differences in the fuel rail itself. Mine only has 1 line on it. I’ve had to piece together this engine with parts from 3 different models lol !! Just something to look for before you dive in and remove everything! Love the video and subscribed!
I just changed my injectors to the 4 port ksuspension ones. This video definitely helped to get the job done. Seems like I have a brand new XJ now. Thanks.
Thanks for the video, and especially for discussing the difference between the pre and post '98 models. I've done this a couple times on my 1990, but now I'm about to tackle it on my 2001 and noticed the different-looking injector plugs.
these guys are awesome! customer service is on point. there was a problem when I ordered my injectors and they personally called me to get it resolved.
This video just helped me do my own fuel injectors myself saving me tons of money taking it to a shop thank you so much!!! Was easy to follow step by step
Just did my 96 ZJ with the 5.2, under 2 hours including going back and forth for the right tools, does run SMOOTHER, Bosch 4 hole for 70.00 on ebay, will check any cold start advantages tomorrow. I used some top quality waterproof grease on the O-rings for the fuel rail and intake side as well, does help a lot
jim dandy I'm glad the eBay set actually worked for you. eBay sellers are a hit and miss most of the time. Sorry we couldn't be your supplier for your injectors this time, maybe next time!
sorry you're having issues, not something we normally run into. Feel free to shoot us an email or phone call and we can help resolve the issue for you. Always here for you.
Just got my injectors in the mail. Kind of a small world. I won them on a facebook group and was looking for a how to video. They happen to be from k suspension. Great video. Will be doing this tomorrow. Thanks for the help and the injectors
2000 4.0 wj IL6. What if you don't reset your pcm? Will it just relarn your new injectors, from 1 hole to 4 hole. I did this and got po172 and po175 oxygen sensors running rich. Cleared codes and ended up replacing my fuel pressure regulator/ filter. So far so good.
HEEP_LIFE the cylinder 3 misfire is caused by heat soak which creates a vapor lock in the fuel injector. Without proper heat dissipation, the fuel vaporizes, causing the misfire. Years ago a TSB was sent out. Search on EBay, Mopar Ignition Cable part No. 56028371AA. sold by AvondaleAutomotive who has a 99.8% positive feedback. The TSB instructs to cut the part in half, installing one piece with the slit facing up and the second piece with the slit down. I also removed the factory heat shield, I purchased mine from Summit racing for less than $25. Part No. 53013669AA , Shield Exhaust Manifold. Pull the throttle cables and fuel injector wire harness. Simple install. I forgot the guys name, search UA-cam for Jeep in-line six, rough idle. Dude will walk you through the install of both parts. This fixed my misfire issue over night. Although sooner or later I will run an auxiliary fan over ride switch because I live in hot and humid South Florida, as well as replace my fuel injectors with the 4-hole remans from K Suspension because some of my stock injectors have cracks. Anyway follow the video and you should solve your misfire issue.
Bought mine from KSus last year, and just installed them today. Idle is very much smoother! We will see what fuel mileage does- from really bad to just disappointing will be a win LOL. I was hoping they would take care of a slight pinging I have, but they didn't. Probably carbon build up...
So originally when I learned about this I figured I would save some money and order some supposed Bosch ones off of ebay... Yea, bad mistake. My Jeep ran like crap and I ended up sending them back. So I just ordered some from you guys yesterday, cant wait to install them now that I know they will be right.
Thanks for the great video. I agree with another post below, you have a talent for this. Well done. My question: do these four hole injectors work with the ‘97 TJ, 2.5? If you also don’t mind, what’s your opinion on this situation my 18 year old son and I dealing with right now. Driving down road, loss of power. Stalls out. Restarts a few times and then won’t at all. Went through a series of things and wound up deciding to replace EVERYTHING we could think of and reach as PM. Started with replacing the fuel pump since there was no pressure. Still won’t start. Good fuel pressure now at fuel rail. Also would not start with starting fluid at this point. Tomorrow morning we are replacing the injectors and the local store has these as an option, which is why I asked your opinion. We are also replacing the plugs, wires, and distributor tomorrow because we have everything torn apart. That, plus the Jeep sat in a field for many years in Idaho and since it’s my sons college daily driver (which he wants to own forever) I figured I would do as much PM as possible while we can. I’d appreciate any thoughts you might have about where to look next if tomorrow’s changes don’t fix the problem. Thank you and happy new year!
First off, Thank You for your comment. Secondly and further, yes, these amongst some other injectors will work for your rig, as for the work you’re doing, no sense in throwing a parts canon at the rig to find the issue. Most problems can be diagnosed easily with a meter and power probe. If you’re in the southwest side of Idaho, feel free to swing by our shop in Nampa. Be happy to help you figure this out. If you’d like some deeper help via messaging, shoot us an email. Be happy to help if we can. Suspensionlifts@gmail.com
I just bought a set from you for my dads 1994 4.0 ZJ, excited to see the difference everyone experiences. I specified it was for a 1994 zj, im assuming that ill receive EV1 injectors right?
It's been 8 years. It hasn't leaked gasoline or anything since you install those injectors right even though you used petroleum jelly? Is it okay if I use viscosity 525 mineral oil to install my fuel pressure regulator?
I'm assuming the injectors on your website would work for a WJ as well, correct? And the 96 dollar price on your website, is that for all six or just one? Great videos man keep it up, you really deserve more subs :)
Tengo cherokee xj un injector no cerraba tiraba gasolina lo cambie e hiso lo mismo es por eso que se apaga cuando agarra temperatura por que se aoga de exceso de gasolina???
thank you for the expert explanation of steps necessary. Just got a 98 4.0 with 114k on it. looking to do some upgrades. I have a question... What is the black plastic rail looking thing next to the fuel rail? mine seems broken.
it's just a cover for the ignition wires, it also acts as a hold down onto the head bolts so that it doesn't move around. they crack/break all the time. You're not alone
Petroleum based lubricants will cause "O" Ring seals to deteriorate and fail. Use teflon or preferably silicone which help keep rubber products supple.😜👍
Very helpful video.I did the swap on my 96 xj.Now my check engine light is on and it idles really rough.did everything like in the video.Is there some other problem that can happen with the swap?
could be a few things, easiest thing to check is first, the code. from there, you can diagnose down each cylinder to figure out what is causing the issue. Feel free to email us for additional support.
Do you have any videos concerning what mods are required to swap the later model curved runner 4.0 manifold onto an earlier model straight runner manifold engine? It seems that I am going to need to weld up a new mount for my PS pump.but I suspect there is a lot more, as it seems that I need to remove a flange off of the newer manifold.
The PO of my 99 4.0 XJ has installed injectors with a blue stripe at the end that's goes into the intake manifold. Any idea what they are? I was going to replace them with a new set of single hole injectors that came with the jeep but wasn't sure if the blue stripe injectors was an upgrade.
Is the PCM restart the same for a 98 Gr Cherokee 4.0? The 30+ seconds of touching the terminal cables together and System on, lights on, lights off, system off?
buenas amigo mi camioneta grande cherokee limite 8cilindros motor 5.2l limpie y los inyectores bien trabajo bien por um mes luego le cambie la bomba de agua, resulta que la prendo y la sorpresa los injectores me empezaron a botar gasolina por la parte de arriba de los injectores le cambio los gomitas por tres veses y sigue igual tiene buena presion de gasolina gracias de venezuela
new problem. Did everything according to the instructions. I reset the PCM, started the car and it's running super rough. is it supposed to do this? not sure what to do.
m medrano after a pcm reset its normal for the engine to rough a bit rough. The idle should clear out after a few minutes. If you're still having issues, send us an email or give us a call tomorrow and we'll take care of any issues if an injector is the problem. They're all remanufactured so sometimes I do see issues arise. I'll warranty out an injector if it happens to be the problem.
m medrano as stated, the injectors are remanufactured and we stand by our work 100%, sometimes issues may arise, and I do apologize about the issue. If you happen to have a faulty injector, once found, we will replace it for you immediately. Send us an email or give us a call tomorrow so that we can narrow down the issue and get it fixed.
KSuspension it says I have an open circuit on injector number 4 but that code was already there with the old injectors and it didn't run this bad. Not sure what to think or do. I may have to put my old ones back in and send you yours back. I would email now but I know nobody's at work on a Sunday at this hour so that's why I'm communicating with you here. sorry if it's bad PR.
m medrano I'm ok with an open service system. Weather we speak here or on the phone, I would tell you the same things :-) Shoot me an email, I'll send you some tips to narrow down the issue and get you fixed up asap! Please include your year in the subject line. I'll be waiting for your email Thank you
Great video, I am about to order a set. But I need some help on a couple of questions....... 1: I also need to replace my fuel rail any suggestions? 2:, I keep getting an evap cope and can’t seem to find the problem. It’s cold starts rough, sometime it will stumble on and a small pop out the tail pipe. Then levels out and idles great after a few seconds. And never does this when starting warm, Not sure if it’s the same issue as the evap code (small leak or no flow) I have changed the fuel lines near the tank and also the evap purge valve near the front P firewall, what should I check next? Thanks.
Hello, I've had times the 97 Jeep TJ 4.0 fuel rail with new injectors "pops" back into the intake ports and times it feels snug but no "pop" with no leaks but damaged a couple injectors. Should you feel or hear a convincing "pop" or not, what do you think?
could be a multitude of issues, either an injector solenoid is sticking open too long, you didn't reset the PCM, the PCM is having a hard time adjusting to the new flow rate, bad MAP sensor, bad O2's, vacuum leak, would have to do some troubleshooting to find the root cause and get it fixed. Feel free to email us for troubleshooting help.
The injector upgrade works for all 2.5, 4.0, 4.7, 5.2, & 5.9 engines If you’re having trouble starting though, I’d find the issue before changing other components. Unless you know it’s your injectors that are holding you up
So i have a 2.3l ford ranger and im wanting to put 15 lb fuel injectors which isnt a huge upgrade but it is an upgrade . do i need to turbo charge my ranger in order to put bigger injectors in it?
Clears PCM memory to remap itself to the new pulse rate of the replacement injectors for optimum performance. Same concept for anything you replace, you should make it a practice to reset the PCM
I am trying to find new seals for mine. I have the exact same yellow ones you sell in your store. My question is what o ring kit do you use? I am struggling to fine the right one with the fiber o ring retainer.
Wayne Harper the Bosch or ford Gen III bodied injectors will work perfectly for your model. Let us know if you'd like to order through us, we do offer a lifetime warranty as well!
Finally got around to putting in the four hole injectors. Jeep runs much better no more long cranks when the engines hot. Thanks for a good product at a reasonable price.

Just installed my four hole injectors this weekend. Can't speak to power or mileage increase but the Jeep runs great.
Was the only improvement just a better running jeep when you put in the 4 hole injectors?

You should really use a silicone based lubricant for injector O-rings to reduce the risk of degradation of the material.
I guess so. Lithium grease is compatible with everything as far as I know.
Is wd40 ok to use??
you’re a natural at speaking and explaining through the camera. good stuff 👍
Thanks you guys for all the help. Your one of the few that actually replied to my comments. THANKS. Keep up the self help videos.
Extremely pleased with the set of injectors for my WJ 4.0 liter.
love the way you explain everything great job, i sub.
Just installed my injectors, runs perfect. Super easy swap! Thank You
These injectors are great. Work perfect. Just installed the four ports in my 89 renix xj. Beats the hell out of paying 70 something bucks apiece.

Did your jeep have a misfire? My #3 cylinder is misfiring but I'm getting spark and power to all my injectors.. do you think my #3 is clogged??
HEEP_LIFE the cylinder 3 misfire is caused by heat soak which creates a vapor lock in the fuel injector. Without proper heat dissipation, the fuel vaporizes, causing the misfire.

Pull the throttle cables and fuel injector wire harness. Simple install.
I forgot the guys name, search UA-cam for Jeep in-line six, rough idle. Dude will walk you through the install of both parts.
This fixed my misfire issue over night. Although sooner or later I will run an auxiliary fan over ride switch because I live in hot and humid South Florida, as well as replace my fuel injectors with the 4-hole remans from K Suspension because some of my stock injectors have cracks.
Anyway follow the video and you should solve your misfire issue.

Hello,
Unfortunately, the people that made this hat are no longer making them. You'll have to have a custom one made.
Do you have any videos concerning what mods are required to swap the later model curved runner 4.0 manifold onto an earlier model straight runner manifold engine? It seems that I am going to need to weld up a new mount for my PS pump.but I suspect there is a lot more, as it seems that I need to remove a flange off of the newer manifold.
no video sorry, but you'll need the PS pump and brackets off a newer jeep to mount onto it.

I’d need to see a photo. Email us
Great video, whats the point of the plastic bits on the end of the new injectors? The old injectors dont have them.
Gone Bush those are called Pintle Caps, and they're main functions are to keep the orings on the injectors, just like a top hat
Just got your 4 hole inj. For my 97 4.0 XJ. So do you remove those plastic tips you sent, holding the i-ring on??

m medrano after a pcm reset its normal for the engine to rough a bit rough. The idle should clear out after a few minutes.
If you're still having issues, send us an email or give us a call tomorrow and we'll take care of any issues if an injector is the problem.
They're all remanufactured so sometimes I do see issues arise. I'll warranty out an injector if it happens to be the problem.
it didn't clear up and it sputtering like an old Buick. not very happy about this.
m medrano as stated, the injectors are remanufactured and we stand by our work 100%, sometimes issues may arise, and I do apologize about the issue. If you happen to have a faulty injector, once found, we will replace it for you immediately.
Send us an email or give us a call tomorrow so that we can narrow down the issue and get it fixed.
KSuspension it says I have an open circuit on injector number 4 but that code was already there with the old injectors and it didn't run this bad. Not sure what to think or do. I may have to put my old ones back in and send you yours back. I would email now but I know nobody's at work on a Sunday at this hour so that's why I'm communicating with you here. sorry if it's bad PR.
m medrano I'm ok with an open service system. Weather we speak here or on the phone, I would tell you the same things :-)
Shoot me an email, I'll send you some tips to narrow down the issue and get you fixed up asap!
Please include your year in the subject line. I'll be waiting for your email
Thank you
I may be calling to order some soon. thanks
Great video, I am about to order a set. But I need some help on a couple of questions....... 1: I also need to replace my fuel rail any suggestions? 2:, I keep getting an evap cope and can’t seem to find the problem. It’s cold starts rough, sometime it will stumble on and a small pop out the tail pipe. Then levels out and idles great after a few seconds. And never does this when starting warm, Not sure if it’s the same issue as the evap code (small leak or no flow)
I have changed the fuel lines near the tank and also the evap purge valve near the front P firewall, what should I check next? Thanks.
Email us some info: suspensionlifts@gmail.com
Idk what fuel rail you’ve seen on a 99 but my shit won’t come off at all I can’t figure this out
Hello, I've had times the 97 Jeep TJ 4.0 fuel rail with new injectors "pops" back into the intake ports and times it feels snug but no "pop" with no leaks but damaged a couple injectors. Should you feel or hear a convincing "pop" or not, what do you think?
usually don't hear a "pop" sound. they just slid in and bolt the rail down.
Thx Raffi for helpful piece of mind. At times I overthink or overpower small parts. Great video.
I did the 4 hole upgrade now I'm getting to much fuel and it's running super rough. Any ideas?
could be a multitude of issues, either an injector solenoid is sticking open too long, you didn't reset the PCM, the PCM is having a hard time adjusting to the new flow rate, bad MAP sensor, bad O2's, vacuum leak, would have to do some troubleshooting to find the root cause and get it fixed.
Feel free to email us for troubleshooting help.
What radio do you have? My stock radio isn't cutting it.
Great video.
Nolan Long I believe the one at the time was the JVC KD-ABT22 it has since been replaced with another head unit
Thanks
I have a 1993 and I;m having problem starting the truck will this work for a 93
The injector upgrade works for all 2.5, 4.0, 4.7, 5.2, & 5.9 engines
If you’re having trouble starting though, I’d find the issue before changing other components. Unless you know it’s your injectors that are holding you up
So i have a 2.3l ford ranger and im wanting to put 15 lb fuel injectors which isnt a huge upgrade but it is an upgrade . do i need to turbo charge my ranger in order to put bigger injectors in it?
this might be a stupid question. but why is it recommended that I reset my PCM?
Clears PCM memory to remap itself to the new pulse rate of the replacement injectors for optimum performance.
Same concept for anything you replace, you should make it a practice to reset the PCM
I am trying to find new seals for mine. I have the exact same yellow ones you sell in your store. My question is what o ring kit do you use? I am struggling to fine the right one with the fiber o ring retainer.
bizzybri feel free to email us and we can set you up with an entire rebuild kit with everything you need to install your injectors properly!
Very informative. Thanks for taking the time to post this video. Remember, safety first.
So what "Brand" of fuel injectors would you recommend for a 2000 jeep TJ?
Wayne Harper the Bosch or ford Gen III bodied injectors will work perfectly for your model.
Let us know if you'd like to order through us, we do offer a lifetime warranty as well!
KSuspension with that lifetime warranty does that mean after 100k miles if I wanted to put new ones in for maintenance purposes does that cover them ?
The ECM reset procedure is interesting. Does this work for the Wrangler TJ as well?
Yes
Awesome video man! Did you notice any gas milage gains? or just a better throttle response?
Thank you!
And mainly just a smoother idle and faster throttle response
Now if your oe injectors are clogged, you'll see a gain for sure
