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.
"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.
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.
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.
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.
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 ?
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)
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
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!
I just want to find the best fuel injector money can buy that are the most efficient and have the flexibility to be tuned for a wide range of power. Basically I want the best mpg and reduced emissions with the most tunability for higher power.
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!
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. 🙂
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.
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?
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
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.
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.
Guy made a video using a very expensive dyno and dyno tech, the tech said before the test there is no difference in performance between 4 and 12 hole using the same injector. Test said the same thing, also showed fancy k&n filter makes less power and lets in more dirt than factory paper. Apples to apples 4 and 12 are the same.
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!
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...
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.
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
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
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
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
Martinbuilt: I’m buying the removal tool through your link I need to know which screens and O rings for the Denso so I can fix this code of to lean on bank 2 . Martin you have the best videos on TH-cam thank you Martin.
@@gregj.gotham4402 Thank you, Greg. I really appreciate your supporting channel. Every bit helps and you will see just how much next year I have a big announcement. 😀
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.
@@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.
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.
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?
Great video idea, Martin! My new-to-me '02 Dakota with the 4.7L V8 has a mismatched set of injectors in it currently - (6) of the white-banded Siemens two-hole injectors (Mopar P/N 53030842) and (2) of the red-banded Siemens two-hole injectors (Mopar P/N 53032145AA). I have been looking into which OEM injector I should use to replace them for the best performance in a stock setup, and had read that the green-banded 4-hole injectors (Mopar P/N 53032704AB) were supposed to provide better fuel atomization. As you demonstrated, that is patently false! I found in the course of my research that there seems to be a lot of confusion and misinformation regarding the flow rates of the three main types of OEM fuel injectors used on the 4.7L V8 in Jeeps and Dakota/Durango's. Would love to see a three-way head-to-head comparison of (2) injectors each amongst the three OEM fuel injectors used in the 4.7L V8: 1) Mopar P/N 53030842 - White-banded two-hole injector, rated for 22.5 lb./hr. at 49 PSI, (Used in '99-'00 Jeeps and '00 Dakota/Durango's) 2) Mopar P/N 53032145AA - Red-banded two-hole injector, rated for 25.8 lb./hr. at 49 PSI (Used in all '01-'03 4.7L V8's) 3) Mopar P/N 53032704AB - Green-banded four-hole injector, rated for 27.6 lb./hr. at 49 PSI (Used in all '04-'07 4.7L V8's) I believe this video would be incredibly useful to many owners of stock 4.7L V8's like myself, who want the best performance without running the risk of running too rich for the PCM to handle.
This is literally what he did in the video. The Denso's are the 12 hole that everyone is swapping in. The Siemens injectors at the beginning are stock in the 4.7's
I have replaced mine to the denzo and a code 0174 bank 2 lean 02 sensor. To many things to list as to why. Intake manifold leak, dirty 02 sensor, vac leak. Runs great just the code so I’m thinking it’s the 02 sensor.
I did clean injectors and put them in the rebuild before starting it up. Yes I’ll agree it could use another cleaning on injectors. I’ll get screen change tool with new screen then rebuild em all.
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.
I don't know how an injector would cause the transmission to shift smoother, did not notice anything like that, better throttle response and a smoother idle I did have.
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.???
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.
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.
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?
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.
@@martinbuilt Good to know. As soon as I can afford some, I'm going to find some Denso ones for my Toyota, and if I can't find any of those, I'll pull some ecoTech type from a Prius or similar.
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.
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!
@@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.
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
Hey Martin! I bought Bosch 3rd gen. 4 hole injectors for 1999-2006 Jeep 4.0 from Precision Auto injectors in Sanford Florida (Great people!!). The injectors are Green(the entire injector) I would like to see them against the stock 1hole that came in my 2000 4.0 Cherokee if possible. Thanks👍
Please do comparison: 12 hole-STANDARD MOTOR PRODUCTS FJ718 against Denso 12582704 12 hole; 12 hole STANDARD MOTOR PRODUCTS FJ462 against 12 hole Bosch 0280156161 ---- much thanks (i got some FJ462 arriving for my 2004 WJ HO motor)
Very cool test.
And a bonus no background music
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.
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.

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
Martin, ECU does not know there are bigger injectors installed, unless you tell it...
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
Do they have to be Denso branded or could they be the aftermarket equivalent? Awesome channel 👍
What would be a Denso equivalent for a 4L5Z-9F593-A from a 2002 Ford Ranger with the 3.0 V6?
That was awesome Martin!!!
Thank you Dan, I'm really enjoying this injector tester.
great stuff man, what do you recommend for a 1.4L engine?
Martinbuilt: I’m buying the removal tool through your link I need to know which screens and O rings for the Denso so I can fix this code of to lean on bank 2 . Martin you have the best videos on TH-cam thank you Martin.
Thank you, Greg, these o-ring and filter baskets will work UREMCO 8 Fuel Injector Seal Kit, 1 Pack amzn.to/2UbAU49
Thank you Martin
Martinbuilt: Just purchased through your links the screens, small hammer and the removal tool. Thank you Martin.
@@gregj.gotham4402 Thank you, Greg. I really appreciate your supporting channel. Every bit helps and you will see just how much next year I have a big announcement. 😀
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.
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.
Awesome video Man I’d love to send you some injectors !! Also how much did that equipment cost you ?

Hi Italy 👋 MISTER.. Big...king
What fluid do you use in your machine?
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!
The diameter of those beakers is much smaller than any vehicle sized combustion chamber. You can't really see the full spray patter.
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
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?

My 05 Dakota 4.7 (N) 53032704AB are splitting top to bottom. So, I'm looking to replace them, suggestions?
Very nice tests.
thank you I'm glad you liked it and found it helpful.😁
Great video idea, Martin! My new-to-me '02 Dakota with the 4.7L V8 has a mismatched set of injectors in it currently - (6) of the white-banded Siemens two-hole injectors (Mopar P/N 53030842) and (2) of the red-banded Siemens two-hole injectors (Mopar P/N 53032145AA). I have been looking into which OEM injector I should use to replace them for the best performance in a stock setup, and had read that the green-banded 4-hole injectors (Mopar P/N 53032704AB) were supposed to provide better fuel atomization. As you demonstrated, that is patently false!
I found in the course of my research that there seems to be a lot of confusion and misinformation regarding the flow rates of the three main types of OEM fuel injectors used on the 4.7L V8 in Jeeps and Dakota/Durango's. Would love to see a three-way head-to-head comparison of (2) injectors each amongst the three OEM fuel injectors used in the 4.7L V8:
1) Mopar P/N 53030842 - White-banded two-hole injector, rated for 22.5 lb./hr. at 49 PSI, (Used in '99-'00 Jeeps and '00 Dakota/Durango's)
2) Mopar P/N 53032145AA - Red-banded two-hole injector, rated for 25.8 lb./hr. at 49 PSI (Used in all '01-'03 4.7L V8's)
3) Mopar P/N 53032704AB - Green-banded four-hole injector, rated for 27.6 lb./hr. at 49 PSI (Used in all '04-'07 4.7L V8's)
I believe this video would be incredibly useful to many owners of stock 4.7L V8's like myself, who want the best performance without running the risk of running too rich for the PCM to handle.
I thank you for your tutorial with all the years and specs on the 3 different injectors. I will run them head to head and we'll see how they come out.
Have you tested these 3 different injectors yet?
@@mrmo666 I'm getting them cleaned up, it will be the next injector video I do.
@@martinbuilt - Have you had a chance to run the white vs. red vs. green-banded Mopar injectors yet? Still awfully curious how these come out!
@@Devin_Schwartz I have not yet, I have been rebuilding a few sets of them.
Great video.can you please run the Densos against the 12 hole injectors that seem to be the rave on the 4.7's.They say incredible gas mileage.
What 12 hole injector are you referring to?
This is literally what he did in the video. The Denso's are the 12 hole that everyone is swapping in. The Siemens injectors at the beginning are stock in the 4.7's
@@Camakid My apologies to Martin I re-watched the video.
I have replaced mine to the denzo and a code 0174 bank 2 lean 02 sensor. To many things to list as to why. Intake manifold leak, dirty 02 sensor, vac leak. Runs great just the code so I’m thinking it’s the 02 sensor.
Did the code show up after you replace the injectors and then if so I would suspect there's something wrong with one or more of the injectors.
I did clean injectors and put them in the rebuild before starting it up. Yes I’ll agree it could use another cleaning on injectors. I’ll get screen change tool with new screen then rebuild em all.
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.
I read that 12 hole injectors cause shifting to be smoother. How does it affect shifting?
I don't know how an injector would cause the transmission to shift smoother, did not notice anything like that, better throttle response and a smoother idle I did have.
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?
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.
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.
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?
2001 DODGE DAKOTA 4.7 WHAT INJECTOR DO I WANT FOR GOOD MILAGE AND SOME TOWING? THANK YOU
well run tests,thanks
Good information about injector comparison
Glad you liked it
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.
so what is the best injectors for 1995 YJ 4.0L ? for direct replacement ?
I would recommend the Bosch 280155703
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.
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.
Did you have to change the fuel regulator? If you did, what brand did you use, and why?
No I've never had to change the fuel pressure regulator.
I'm sure most fuel injectors will operate just fine with your OEM pump and regulator.
@@martinbuilt Good to know. As soon as I can afford some, I'm going to find some Denso ones for my Toyota, and if I can't find any of those, I'll pull some ecoTech type from a Prius or similar.
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.
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.
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
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
very cool!
hi what fluid do you use for the flow test and the ultra sonic bath?
Hey Martin! I bought Bosch 3rd gen. 4 hole injectors for 1999-2006 Jeep 4.0 from Precision Auto injectors in Sanford Florida (Great people!!).
The injectors are Green(the entire injector)
I would like to see them against the stock 1hole that came in my 2000 4.0 Cherokee if possible. Thanks👍
4 hole Bosch part # is:
0 280 155 789
Thank you, I may a set of those injectors.
Please do comparison: 12 hole-STANDARD MOTOR PRODUCTS FJ718 against Denso 12582704 12 hole; 12 hole STANDARD MOTOR PRODUCTS FJ462 against 12 hole Bosch 0280156161 ---- much thanks (i got some FJ462 arriving for my 2004 WJ HO motor)
