I’ve had the 4 holes for a year or so now. Freaking fantastic. Great work friend
Great job Raffi! This is one of your best videos to date! I love the 4 holes on my '90 XJ. Improved gas mileage and performance for us! Thank you
Just ordered a set from you for my 4.0. Thanks for the detailed video!
Running raffis 4 port remanned ones for 3 years now still working great.
Well done! Loving my 4-ports 😊
This video is Gold
Thank you !!
Ordered a 4 hole set from Amazina, they ran great for nearly 35 miles before failure. Ordered a set from you. Lesson learned $40 too late, but it was learned.
Great video educational and relatable awesome 4port👌
Nice presentation but had a hard time seeing spray patterns because of the glare at the top of the glass tubes
Awesome video
I'm just about ready to order a set of 4 port injectors from you for my 2000 XJ, couple more weeks
Thank you so much 😊 it helped my questions
Interesting: I have both of those devices on the counter. They come in very handy.
I don't know about the spray on the 1st test for the furthest left injector. There seemed to be some streaming. I'd think the added cost would pay for itself with better mileage and less maintenance. Great video.
And that's why I bought your 12 hole injectors!
Fanastic video👍! Thanks for sharing!
Thanks buddy
I run 4 hole remaned Bosch there awesome
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.
How are they now that you installed? Any difference?
E-bay strikes again !! When will folks learn that cheap prices mean cheap crap !??
5 stars! ⭐⭐⭐⭐⭐
Definitely a good spray pattern on your 12 port injectors.
The 12 ports looked terrible compared to the 4s. Glad I have the 4 ports now
I wish I would have seen this video BEFORE paid the $ and go the cheap ones! UGH. Two of them didn't work at all!!! Now I'm gonna have to pay out AGAIN and get some good ones! UGH UGH UGH. Lesson learned!
Many years ago, an Oil Company used the best slogan I've ever heard:
"The Economy of Quality" -- after that message sunk in, I NEVER buy anything by it's price alone.
Nice to see a little side-by-side comparison to get a feel for how each injector pattern looks. My only gripe is that you don't mention specific advertised flow rates. Not all Jeep injectors use the same flow-rates so what may work for some, may not work for others. I'm sure it's nice confirmation that the chinese imitations do have their shortcomings in performance though.
Good note. I guess I wasn’t thinking that far ahead. We already categorize each model in separate years on the site, so didn’t even think to mention it. Was just doing a visual representation of what’s good and what’s not
My experience with a similar injector machine is the more atomization there is the more fuel I have to pull out of the fuel map on a stand alone efi system. The factory ecm is very limited on its adaptive strategy to these kind of changes as it only can use its long and short fuel trims you cannot change the base fuel map.
I bought a new set of single injectors 200.00 they leaked badly , very Heard- to start, so I had to put old ones back in started great. 200.00 and they leaked 1AAuto and their second set leaked too
Looking for some good 4 port injector Help liked your demo.
It is true. Running rich is mostly what those cheap one will do on those 12 holes ask my CAT and O2 sensors
I bought some of those chinise injectors they are already on the car will it be fine to start it up?
You’ll be fine. Just may not run properly

From the looks of the video the 4 port bosch injectors where the best. It looks like it sprayed better than the 12 port bosch injectors. I thought the 12 port would flow better than the 4 port. Is this the actual case? Or did I just not realize the 12 port was actually better?
As far as the mist pattern, 4’s were better. Check out our dyno video, shows the output differences in the different injectors as well. Each has its own purpose for different builds
@@KSuspension alright thanks and I will check it out!
I have the CT150 / 4 cylinder tester and 2kcc injectors suck it dry and it can't do much more than idle test without the fuel pressure dropping super low. What size injectors are you testing here?
these injectors aren't anywhere near 2000cc, those would bleed this tester dry as well. that's a lot of fuel. These are 240cc injectors.
thanks very much for choosing our Autool product, if you have any question, please contact us : aftersale@autooltech.com
You mention the computer adjusting for it, but I don't see how it can tell which cylinder is getting less fuel with a set of knockoffs. Wouldn't you risk running a cylinder lean?
Great video by the way! Thanks!
The computer in the vehicle can only adjust so much. If the injector itself isn’t firing properly, it’ll cause issues.
So, to me, the 4 port OEMs were the best. Would you recommend the Bosch 4 ports?
absolutely! They're one of the most popular items our customers get for their rigs.
Awesome! Thanks. From my research I need the 703’s for a 95 XJ?
Clint Rowe that’s one of the ones that’ll work yes. Common upgrade :-)
Thanks a bunch!
Hello,
Could you tell me what 4 hole injectors fits for my jeep wrangler yj 2.5 - 4 cilinder - 1991.
Thanks inadvance.
There are a multiple number of injectors that work.
Between Ford, Chrysler, and Volvo units. All work great!
Your JEEP will perform best with the 4-Hole, Bosch/Ford fuel injector design.
Best replacements for those fat-bodied early injectors = 4-Holers - OEM for '98 Panthers -- slim design looks cleaner -- NO large metal heat sink to boil your fuel while on the trail.
Does a 4 hole injector use more gas that a single hole injector ? Which would you recommend 4 port or a single port ?
No they do not. and multiport will be a better option over the single port OEM design.
NO. More holes doesn't mean more gas.
The JEEP 4.0 and the FOMOCO 4.6 2v use exactly the same 19 lbs/hr injectors.
The early models with the fat metal bodies would often boil the fuel while on the trail.
The Bosch/Ford injectors from the '98 4.6-liter FOMOCO engines have the newer, slim design that runs much cooler and doesn't boil the fuel under the heat of the desert.
The '98-up Bosch/Ford (4-Hole) injectors are the perfect solution for your JEEP engine's smooth idling, grunt-crawling, and hill-climbing, too.
NOTE: ALL of the 12-Holers are 24 lbs/hr -- TOO BIG -- your JEEP needs the 19 lb/hr, 4-Hole Bosch/Ford design for all-around best performance and economy.
Same injectors as used in the famous 95 MERC:
www.mercuryforum.com/forum/grand-marquis-14/1995-grand-marquis-restoration-8937/
Where the hell do you get oem 12 holes? I've never even heard of that.
OEM JEEP fuel injectors are 19 lbs/hr, 1-port type.
Your JEEP performs best with the Bosch/Ford, 19 lbs/hr, 4-Port injectors.
The 12-holers are all the 24 lbs/hr type -- too big -- that's why they ain't OEM.
Ok, so I'm sold on upgrading my injectors! How does one decide on the 4 port vs. the 12 port?
I have a 2004 TJ BTW . . .
4ports for more top end, 12ports for more bottom end, and either choice would be plug n play in your 04 TJ
Excellent I've got some 4 port for my Cherokee, cheap one they work , years ago I put Ford 5.0 in and these seem too be pretty much the same but half what I paid years ago 🤷
and where is this injector tester made? looks special to me lol
i got a question if I have oem injector 1pin hole @ 243.8cc p/m and swap for 4pin hole 232.1cc p/m, will the 4pin hole spray more fuel than the single pin hole?
Hello,
No, the 4port will not spray more fuel than the single port OE units
@@KSuspension okay in that cause since i keep getting the the 02 voltage hi rich condition I think the Chinese injectors are stuck open
@@joeydelmarsjr.646 might have a unit sticking open longer than it should.
@@KSuspension thank you for the help, I plan to getting genuine bosch injectors for 97 5.9l magnum
@@joeydelmarsjr.646 let us know when you're ready, we'll get them out for you!
hi what fluid do you use for the flow test and ultra sonic bath?
Basically fuel injector cleaner for the flow tester. A special solvent for the ultrasonic
@@KSuspension any brand solvent you recommend i recently purchase a machine i just dont want to use the wrong product
Kevin Kassie for the ultrasonic? Any cleaner will work, just don’t go with a high acid base
@@KSuspension can you say what adaptor is required for a 850cc injector type i dont know if i need a special adaptor for those because it really diferent non of my adaptors works?
@@kevinkassie8573 I couldn't say, we don't do that large of an injector.
Gfeat info
I wish my experience with your injectors was 100%. It does seem smooth at cruise speed, it does start right up. Loss of some city mpg, slightly rougher idle at stoplights, rougher at passing acceleration, not as snappy passing. Jeep would slightly slow on hills before, now it has to downshift and seems to struggle to maintain speed. After using them for 6 months, and scanning every possible problem, I'm going back to stock so I can have my old Jeep back.
I wish you would have emailed us with any issues so that we could fix it. We have a lifetime warranty on all our units and stand behind our work. Could be something super simple causing those issues. Sorry you were experiencing problems. Hopefully next time you’ll allow us to help you out before throwing in the towel.
@@KSuspension Oh, I did, several times, but I got zero response. This is the very first time I have received any response from your outfit, and why I didn't buy the big 3 or the coil kit. I held off months to submit my review of the injectors, waiting to see how you would handle this.
R. Weaver we have never not responded to anyone, forward your original email to us again, I personally handle all the emails and messages and have a complete record for the past 6 years, every single email and message gets a response, even if it’s just a confirmation, so your email either never got sent, or you typed our address incorrectly and it never came through.
I do believe you sent a message, as you stated, but I cannot believe that we didn’t respond, as I always do.
Shoot us an email with your order information and I would be happy to assist you.
I’ll keep my inbox open, waiting on you.
O rings with more recycled rubber are stiffer
Note: I subscribed to your channel and gave this a like! I'm new to this. So, what were the names/manufactures of the Chinese injectors and were they listed as the upgraded ones you tested? Just so I can stay away from them? I want to change from my stock single port to a 4 port injector on my (Feb) 1993 Jeep Grand Cherokee Laredo I6 4.0 I've gone to different sites and they all have different info amongst each other on selling me the correct injector for my application here. Just want a decent set of injectors and not a knockoff set either. Do you or anyone reading this know of a reputable place that sells them and possibly has a phone # also??? I would really appreciate it so much!
Dah, just noticed that you do sell them. Which ones do you recommend for my particular application?

Okay I get it no Chinese injectors
Which uses more fuel
1 4. 12 port injector ?
The ONE (1) and FOUR (4) port injectors for the JEEP 4.0 are flow-rated at 19 lbs/hr.
The 12-port injectors are flow-rated at 24 lbs/hr, TOO BIG to work properly with the ECM.
Go for the 4-Holers !!
19lb or 24lb?
injectors are stock replacements, rated at 19# at 43.5psi 3bar measurement.
@@KSuspension so do you guys offer a 12hole in a 19lb injector or just 24lb? I have the stock ones on my wj. Which is best for fuel economy?
@@pablomarquez4431 12ports are all 24#, economy is entirely based off driving habit and build type, but we have seen better results with the 12's
@@KSuspension thank you. Love the viper plate kit you guys have. Will be doing that mod as well. Thanks👍👍
Bosch injectors from China are absolutely junk. just got some 4 hole K's open the bag all excited about this had the Ford oval on it... we will grind that part off.. jokes, awesome for me thx, back order for a month wasn't mad about that either.
Thank You for being patient with us. Trying to get ahead as fast as possible!
thx for your reply.
Those Chinese injectors are NOT made by Bosch -- they are counterfeits -- made to LOOK LIKE the real Bosch/Ford injector design.
@@SlikLizrd kinda figured that when all 6 were stuffed into one Bosch box. k suspension injectors are the real deal. I'm now getting 17mpg with 280k miles of fun on my ticker
@@wesleypainter2657 I'll take your word, Wes --
The famous 95 MERC has the Bosch/Ford 19 lb/hr injectors from the '98-up models -- the early ones have big, fat metal bodies that act as heat sinks. No Bueno!
The '98-up ones are slender, without that damned heat sink.
MUCH better here in the desert heat.
The majority of used or rebuilt injectors on Ebay are not Chinese. They’re factory Bosch etc.
NAH. If you buy auto parts from e-bay, you really don't know WHAT you're getting !!
Como eu vim parar Aki?
cheep chinee clap.
Look! I was really interested in your video until I heard this or that about chinese parts! It's all bullshit anyway! Really it's about availability! Honestly I'd like to order parts as they where or get the parts that I want and work! Cheap politics and hassles for no reason! Anyway! Cheers! Just a very frustrating industry fixing things all the time! Did I fail to mention funding? Had some guy who could have carried some of the weight in repairs show up to my house the other day with a 70,000$ truck saying he has a shop. I have a vehical from 2000 and I spent my last bit of money on a battery charger that was on sale because most people expect you to bring your vehical to thier shop even if they are helping! Ah, well! We keep on keeping on I guess
