Very cool test.
And a bonus no background music
That's quite a neat tester you demonstrated for us. Appreciate the patience you used to demonstrate this for us. Thanks!
Glad you liked it.🙂
Great job on the video, I just ordered the 4 port version and I love it. Thanks for posting, I will be posting some videos using this awesome tool as well soon. But in the mean time you really helped me understand better what I was looking for and I just purchased a set of fuel injectors that I hope help my car run better and have better fuel economy.
Another great video sir!!!! So happy I followed your original advice and went with those 12 hole injectors! Thank you!!!
You are very welcome! Hows the 4.7 running with all the mods you have done?
Saludos desde España Martín!! Gracias por lo que haces, es muy útil para los que tenemos un WJ 4.7.
Animo y sigue así 👍
Otro como yo , has probado los denso ?
Genial!!!!!!!!!algo que esperaba ver hace mucho tiempo!!! Muchas gracias!!!!
"We all got a new Fi tester".. thanks! :O) I have no doubt you R the "Injector Whisperer" now (3 years later:). Some really good info in your videos. I like the way your gray matter operates.
Very cool test Martin!
Is it possible to use those Denso injectors on other applications than 4.7L, like a Ford 3.5L Fusion Sport? Or are they built with a particular rating in mind? Sorry, I don't yet know much about injectors, but I'm doing my research. Great video, I've subscribed and look forward to learning more!
More people like you should exist. This explains why my car was runnin funky after my friend put some "new" injectors.
Thank you, I appreciate that
Hi Martin,
Been following your built for some time.
I have an 2004 WG (European WJ) with the red Bosch injectors on my 4.7 HO.
I have recently acquired an DRB III emulator and I can see that my long term fuel trim is at Negative 20~18% and even the short term trim ones are negative 16~18%
Can the injectors be the cause? do you have any idea how are your fuel trims with your Denso injectors?
Thanks and keep up working on that great machine
Very cool. Would like to know what you think would be the best upgrade injector for my 98 Cherokee xj. 4.0L
mein...you guys in the states have all the fun! I have never seen a test like this done before.
Glad you like it, maybe some day you'll have to visit.
Do they have to be Denso branded or could they be the aftermarket equivalent? Awesome channel 👍
Hey Martin you have some great detailed videos! Some injectors i would love to see compared are the oem injectors form 02-06 tahoe/suburban the flex fuel injector vs non flex and the way the perform with there different pressures (flex trucks 48-52 non flex 55-62)
great stuff man, what do you recommend for a 1.4L engine?
Hi Martin great video very informative ! I have a 2005 Honda CRV with a 2.4 engine it has over 204k and I need to replace the injectors, as far as I know they are the original injectors. Do you think its worth me replacing the filter baskets and cleaning them ? If not what injector would you recommend Thank you in advance
cool. hope to see lots more comparisons
More to come!
Hey Martin, I love your videos, I subscribed to your channel as soon as I bought my dodge. I just got bosch 0280158103 injectors with 12 hole and 259cc flow rate for my 07 Dodge Ram 1500 4.7. What is your opinion on those? Can you do a test on them? You can find them on the Mazda 2.3 L3 motors. Thanks in advance!
Hey great video good info maybe a better up close camera shot of the spray pattern and would love to see some chevy ls injectors new vs old and e85 thanks
Thanks for sharing. Have you compared Bosch 23bls 4 port MDH-94-855 injectors?
hi what fluid do you use for the flow test and the ultra sonic bath?
Another Great Video on 4.7s. Would be delighted to see a series on building your HO engine. I have a 04 HO with 197K miles that is due for a rebuild. There are TH-cam videos on the rebuilding , but your TH-cam videos are fair more detailed and superior.
Will do!
Green Bands are in the 2004-2007.
All my 2004 4.7's had/have them.
Awesome video Man I’d love to send you some injectors !! Also how much did that equipment cost you ?
those look like the slightly older style ev6 injectors does the new ev14 4 holes do any better? also marine boat injectors with the ball style would be cool to see!
Cool vid and Cool test, could you test the Carquest Injector?
Hi martin nice comparison. Is the AcDelco GM Original injector 217-2907 and the same injector as the Denso 12582704 these for a wj 99-04
Thank you in advance for your answer
Cool test. Listening to see if one is louder? My new denso 12 holes tick.
What fluid do you use in your machine?
Hey the link for the Denso injectors is still good on Amazon? I been eyeing them but the part numbers looked different than what you put on the screen
This was eye opening! Thanks for the info, I'll be picking up denso to replace my green banded cracked injectors.
Yeah you'll like them, another good choice would be the Bosch 280156161
I picked up a set at the junk yard Denzo 12582704 12 holes at 6.00 each 1.00 core. Cleaned them out. new is 490.00 for 8 of em. Go to a junk yard you won’t regret it.
i've got a 2008 ram 1500 with the 3.7 v6. got a miss that i feel is an injector, so i want to replace them all. i want to use the Denso 12582704 but i can only find matched sets of 4. where could i find a flow matched set of 6 or 8 if need be.
That was awesome Martin!!!
Thank you Dan, I'm really enjoying this injector tester.
Martin,
I drive a Buick park avenue with a GM 3800 model 2 ultra engine. I do that in the Netherlands in Europe. In the USA that is a car for grannies but in Holland it is a real car from the USA and therefore really nice.
In your opinion, what is the best injector (make and model) for the best performance and fuelmilege?
excellent video .. nice kit .
Enjoyed. Do an injector test for 4.0 IL6... what might be preferable under load test.
i agree would like to see a 4.0 i6 injector comparison!
Yes i would like to know why the old honda city fuel economy is much better with its 6 hole fuel injector...what could be the secret behind it.
@@OverlandVideos iou
Yeah, the 703 X four holes vs OEM two hole and other 12 hole injectors.
Very nice tests.
thank you I'm glad you liked it and found it helpful.😁
Hello martin,love the denso upgrade demo,been smelling fuel on startup but see no leaks yet,thinkin its time to change out mine.not sure i want to chop up things to make densos work,so just curious the bosh 12 hole type is that for a 4.7l and is it just plug n play or do they also require tweaking to fit,also how much they run for 8 pieces???? 2002 limited,snookie pa.???
Hi Allen, I just had that happen to my 04 Durango. Wondering if you tried the bosh and if so, did they work better?
Great video. The machine removes all the variables and with a direct comparison, it was easy to see the performance of the individual parts.
exactly, that's what I love about this Tester
Nice, I just paid a diesel shop to clean and flow test some scrap yard injectors
great video thanks martin
Glad you enjoyed it
So I have been using your videos alot here lately trying to do the ho cams and intake swapping. I've got a question for you and see what your opinion is on the issue. I know I've seen some car guys wrap the injector rails with heat shielding tape. Does that do anything for improvement on fuel mileage and power, or it a waste of time?
That is actually a good idea I have done it to my 4.0 in my XJ, it would be a performance mod.
I have a ford 2011 Ranger with a 4.0L I’m not sure what stock injectors it uses but I’d really like to find a better preforming one if possible
What would be a Denso equivalent for a 4L5Z-9F593-A from a 2002 Ford Ranger with the 3.0 V6?
I have a 5.7 L Hemi and I was just wondering what injectors would give me the best fuel mileage 42lb or the 95lb?
very cool!
Do the imfamous 12 hole ford. Vs the 4 hole
Hello, can you suggest what is the best brand of gasoline injector cleaner for dosing annually into fuel tank?. Or your experinces or testing says that injector cleaners does not work!. Fuel dilution in engine oil originates from poor injector spray?. Thanks.
What is the injector that filters the gmc Sierra 2006
4.8 . machine? fuel economy
Hello, I have a 2000 camry 2.2l with high postive long term fuel trim at 20% at idle, but at higher rpm it drops to 5%, but I cannot find a leak, would a exhaust manifold or intake manifold leak would cuase this? I also have do NOT have check engine light on.
Amazing content, thanks!
Glad you liked it!
@@martinbuilt Im interested in purchasing a valve spring compressor from you, I messaged you on FB. Happy new year!
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? can the 5.9L magnum benefit from 4pinhole vs the oem 1pin hole?
Maybe test all the different injectors for the 4.0 and the 24lb Ford injectors for the strokers
Hi, have you measured how much the fuel economy improved after changing the injectors?
Awesome video!! Thanks for taking the time and showing us mechanic heads what fuel injectors are the best for the 4.7l
Glad to help
i just bought the ulta-power mf1475 injectors can u compair them to the benso,s
My 05 Dakota 4.7 (N) 53032704AB are splitting top to bottom. So, I'm looking to replace them, suggestions?
Martin! Still waiting on a walk around your grand Cherokee! It’s a sweet ride!
Working on it
Was wondering if you could adjust the pressure of each injector to test at the specific pressure of the fuel pump in different vehicles or even if it mattered ? Fun stuff !
I am able to adjust the fuel pressure but not individually. I usually try to run them at 3 bar or 43.5 PSI. That way, you're always comparing apples to apples.
Thank you for watching. 🙂
Anybody have experience with the Bosch 12 hole 24lb injectors? I got the s&j stroker on the way And wanna get the rest of my parts here
2001 DODGE DAKOTA 4.7 WHAT INJECTOR DO I WANT FOR GOOD MILAGE AND SOME TOWING? THANK YOU
what kind of fluid do you use?
I would like to see some China gm injectors against some used oem gm injectors. Thanks
Any updates on the injector bench tester? Long term review of the machine? Would you buy the same one again or look elsewhere?
Thanks!
I still like this machine the only issue I've had is with the ultrasonic cleaner it is not thermostatically controlled or have a timer so do not leave it unattended. Like I did and after being on for several hours it burned up, not literally. I ended up purchasing a larger ultrasonic cleaner that had a timer with temperature control.
Hi Martin, I've been playing with few injectors from my jeeps and around th same test bench and something strange happened,,let me tell you, I bought a set 24lb Ford Racing injectors for my Renix with no cat French export version, before installing them, I bench tested both type, the Yellow 4 ports BOSCH 0280155746 19.9lb Vs New 24lb. and then....what ever were the test, idle, speed test, hi flow etc, each time the bosh were spraying more fuel. I said to my self, it can't be, so I installed them and as I run open loop in stock form and as I dont have fuel trim but an after market wide band lambda, I can check my AFR and of course, my lambda dropped from 1 to 0.9
So in the test bench, they look to flow less but more when mounted on the engine.
Few days after, I came back to the test bench....why is that....I started to make test again, same result, then I look to machine parameters, I found that pulse width can't be adjusted on all tests, why is that, during hi flow test or other it's like pulse is way too short compare to real pulse width ( 5 to 20msec from idle to full load on E85 on a 5.9 for exemple )
Only on idle test I have been able to crank PW from 3 to 20ms, and than as soon as I start to increase PW, the for Ford racing start to deliver more fuel than the Bosch.
What do you think ? what was your pulse width during test ? have you been relying on the bench test pulse width ?
Very informative. Want to change the Injectors on my 2006 Dodge Ram 1500 TRX4 with a 4.7L V8 as the engine seems to be under powered and a dog like the Chevy 305cc of the 1980's. Will the Denso Injectors significantly boost the HP and performance? Also got an K&N Air Intake on the Truck. It also has a 390 Rear End. Can I also buy Denso Injectors new online? Do any modifications have to be made when one uses the Denso Injectors? Are there any other Mods that you can suggest that will enhance the performance? I also have a 2006 Jeep Unlimited Rubicon with a 4.0L I would like to change the injectors on as well. Both Vehicles have a 6 Speed Manual Transmission.
I like the 08-13 intake manifold with a larger throttle body. Also a free-flow exhaust system. I would recommend these injectors be used on a modified engine.
I just subscribed sir. I like your channel
Thank you I appreciate the support.
Can you run a rest on 4.0 injectors vw injectors etc. I see lots of opinions but you now have a way you prove it. I actually run a 4.6 stroker but not sure if my 93 electronics would run any of the injectors you tested.
yeah can that, I'm running the Bosch 280156161 in my 98 Cherokee XJ with the 4.0 and those work great.
Would love to see dirty to clean injectors and what cleaners were used.
Great suggestion!
Good information about injector comparison
Glad you liked it
In the description for Denso 12582704 - wrong link for AC Delco injectors. Is it the same as AC Delco 217-2907?
I couldn't find any spec. on those but, they look very similar.
Great video!!!
Glad you liked it!
simple question I already know but need confirmation, do most injectors fit size wise, I need to replace a few and Im just going to do all 6. I want to put those densos on my charger which I think stock poundage is 24lb injectors. They are 4 hole as is.
Yeah there are many that interchange no matter what the brand is but there are some out there that are either much shorter or somewhat shorter than the typical Bosch or Denso injector.
Like the injectors found on the 2008 through 13 4.7 are shorter.
awesome video man, im looking at upgrading my injectors and ecu(haltech) on my m271 c200k and have been scouring the internet but no one likes to talk about efficacy its all about flow numbers, i want the best performance not just the peak performance and if the better injector improves torque throughout the entire rpm range and not just peak then so be it, motors are just heat engines and extracting more heat into work is the aim of the game.
Thank you. I really do appreciate that i'm glad you liked it and found it helpful.
Also do you sell the injectors.
Thanks for that very interested video. I am trying to upgrade my 91 Festiva / Kia Pride injectors to something more modern and efficient.
I'm glad you found it helpful 👍
Would these Denso injectors work in a 4.0 jeep? What’s been your experience there? Trying to get the best option for my engine.
How about doing your own research? Or is asking questions easier.
That machine is sweet! How much to bench test my injectors? Are four hole better than two. I'm rebuilding my top end and I got to tell you those Chrysler components even after 60,000 miles I had it rebuilt in 2016. You look new valve seals and the injectors look amazing
I need to do a comparison with the white, green, and red band injectors which have better flow and spray patterns.
Regards!! I am having problems with my machine, when I try to drain it’s start the timer but does not drain... How can I fix this problem? I will appreciate your help with this problem!!
I really don't much about how to fix one of them. Have you tried to unplug it? That might reset it.
so what is the best injectors for 1995 YJ 4.0L ? for direct replacement ?
I would recommend the Bosch 280155703
Hey Martin will that Denso fit for 3rd gen Hemi? Thanks
I would have to look into that, not to familiar with the Hemi's
Hi what type of ultrasonic fluid you use? What brand pls?

Hey Martin! Another Vegas local here with a 4.7 WJ. Have you ever experienced a rough idle and engine shake intermittently? Usually happens after engine has been running and is restarted after a short break and lasts no more than 5 mins, correcting itself eventually, only to happen again randomly. I replaced my spark plugs hoping that would fix my issue. Thinking about replacing the fuel injectors next. Do you think they could be my issue? Thanks in advance!
check the fuel pressure at the rail make sure you have around 49 to 52 psi. Any code like a misfire code?
@@martinbuilt Thanks for the quick reply Martin! I do have a code, P0442 for a small evap leak and have smoke escaping from my driver side rear bumper, similar to the issue you had.
Just found your channel, you seem to be a very knowledgeable mechanic, at least a darn good injector man. I have Keihin injectors on my 2011 Triumph America I'm working on now. Do you know much about Keihin fuel system? I'd like to see how they look on your machine. Thanks for the informative video, God bless.
Thank you, sorry I'm unfamiliar with Keihin injectors.
@@martinbuilt Well, nobody knows everything, lol. And, One never knows till they ask. Still I learned from your video, and appreciate your honesty. I will be a subscriber from now on, to see what else I can learn. Thank you for taking the time to answer my question, and make the videos you do sir. I'm nearly 53 and am pretty good with carburetors, been tuning them all my life, but all this computer controlled apperatus is like learning Greek in some ways. I'm catching on but search for every morsel of information. Again thank you sir, and God bless.
Martin, what is you opinion of your tester compared to other affordable ones? I was thinking of buying that model, or the Autool 150, 160, or 200. Thanks
The one thing that the Autool testers have is a reverse flush I had to modify mine so it would do that. I also liked the fact that mine had a separate Ultrasonic bath At was not built into the machine.. Even though I burnt up my ultrasonic bath because there was no timer or heat control you you cannot leave it unattended. I replaced it with a another ultrasonic bath that was much larger. I have several of Autools equipment and I like their stuff I don't think you can go wrong with either one.
@@martinbuilt Thanks, how is the warranty and support on the Morphorn? Autool appears to have good "stated" warranty and support. I didn't find much on Mophorn related to that.
what year grand cherokee are you running the densos in
04 Jeep Grand Cherokee WJ with a 4.7
Im glad you did this test...we were discussing this a while back...
So what are the White Band injectors?
I have seen those before, I'll get a set next time to Pick-a-Part
Awesome...id like to see because that was the original set in my 2000 dakota
The white-banded OEM fuel injectors for '99-'00 Jeeps and '00 Dakota/Durango's equipped with the 4.7L V8 are Mopar P/N 53030842. They are a two-hole injector rated for 22.5 lb./hr. of flow at 49 PSI stock fuel rail pressure. Many reported they underperformed and flowed closer to 19 lb./hr. at 49 PSI. It's possible that's why they were so quickly discontinued in favor of the red-banded Mopar P/N 53032145AA injector starting in 2001.
@@Devin_Schwartz gotcha...so even more reason for Martin to test them :)
@@Kolonol1 - Precisely! I would love a test comparing the white, red, and green-banded OEM Mopar fuel injectors head to head.
Nice video.
I'm glad you liked it and found it helpful Thank you for watching.
Why don't they make ultrasonic fuel injectors? Just straight mist it into the chamber? Wouldn't that provide a more efficient or total burn?
I wish you could do one video on Hitachi for D 21 Nissan 2.4 OEM vs. aftermarket. I got a set of Chinese knock-offs and, brother I paid the price (literally) OEM runs $ 200 a piece
Good morning Martin, would you know the specs on stock 4.7l fuel injectors?
Here is what Witchhunter has on them www.witchhunter.com/flowdatapix/s53032145.jpg looks like 255cc @ 3 bar
24lb injectors?
Is it the the audio in the recording or was the injector pulse cutting out on the machine?
it's the audio, the machine runs perfectly.
nice job try 156 2.0 alfaromo injector
Did you ever put your 4.7 on the dyno after all the mods?
No, not yet
Good Martin how much cost that machine thank you you are so smart
your looking at 500 to 550
That high speed test do you know what rpm is that in car?
I'll have to check but I know that it's actually much higher than most cars will ever run. I wanna say 10000 RPM
Well all my family at is finally done and I can get back on my 4.7...i got the Denso fuel injectors out of the junk yard...gotta clean them up and get them in...
Do you still have your Cherokee? I would like to see a comparison between oem xj 4.0L injectors and the common doge neon 4 hole injectors. This swap has been around so long i guess there's the 12 holes as well. From what I've seen, it should NOT improve mpg as your pcm will provide the same amount of fuel regardless of the flow rate and amount of holes in the injector. Off idle it should be smoother though. The 4.0L is a dated engine now a days and modern injectors don't seem to make a difference
yeah still got the XJ. I can do a comparison on several of the popular injectors and the stock ones for the 4.0
@@martinbuilt that would be awesome! Thanks for the reply
Other than the Larger Air intake and the 08-13 Intake Manifold you would not recommend the Denso injectors for my vehicle? I am not sure what a Free Flow exhaust is.What other modifications are you suggesting? No one really makes aftermarket High performance parts for this engine, that I know of. I like my wired Intake and do not want to go to a fly by wire. I like Simple. If I was to put the Denso Injectors on without mods, you are saying that I would have problem with the vehicle.
