Injector Comparisons

[@mitchelfrench253]

I’ve had the 4 holes for a year or so now. Freaking fantastic. Great work friend

[@MattyGgardneR]

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

[@_JEBUS]

Running raffis 4 port remanned ones for 3 years now still working great.

[@WanderingDad]

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.

[@Foryourinfo369]

Just ordered a set from you for my 4.0. Thanks for the detailed video!

[@johnkarkoska6963]

Nice presentation but had a hard time seeing spray patterns because of the glare at the top of the glass tubes

[@Khell3770]

I'm just about ready to order a set of 4 port injectors from you for my 2000 XJ, couple more weeks

[@cjv2131]

[@NickInTimeFilms]

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.

[@KSuspension]

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

[@oregonhighway]

Well done! Loving my 4-ports 😊

[@popedwards8986]

Does a 4 hole injector use more gas that a single hole injector ? Which would you recommend 4 port or a single port ?

[@hndaxr400rdr]

No they do not. and multiport will be a better option over the single port OEM design.

[@SlikLizrd]

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/

[@acokedupmonkey3762]

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.

[@jamesruiz4005]

How are they now that you installed? Any difference?

[@SlikLizrd]

E-bay strikes again !! When will folks learn that cheap prices mean cheap crap !??

[@austynchavalia]

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?

[@KSuspension]

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

[@austynchavalia]

@@KSuspension alright thanks and I will check it out!

[@jeffreydurham5342]

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?

[@jeffreydurham5342]

Great video by the way! Thanks!

[@KSuspension]

The computer in the vehicle can only adjust so much. If the injector itself isn’t firing properly, it’ll cause issues.

[@mattcero1]

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.

[@Iahusha777Iahuah]

Where the hell do you get oem 12 holes? I've never even heard of that.

[@SlikLizrd]

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.

[@roccom5988]

Hello, Could you tell me what 4 hole injectors fits for my jeep wrangler yj 2.5 - 4 cilinder - 1991. Thanks inadvance.

[@KSuspension]

There are a multiple number of injectors that work. Between Ford, Chrysler, and Volvo units. All work great!

[@SlikLizrd]

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.

[@electricstartclint]

So, to me, the 4 port OEMs were the best. Would you recommend the Bosch 4 ports?

[@KSuspension]

absolutely! They're one of the most popular items our customers get for their rigs.

[@electricstartclint]

Awesome! Thanks. From my research I need the 703’s for a 95 XJ?

[@KSuspension]

Clint Rowe that’s one of the ones that’ll work yes. Common upgrade :-)

[@electricstartclint]

Thanks a bunch!

[@2slofouru]

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?

[@KSuspension]

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.

[@aftersale9337]

thanks very much for choosing our Autool product, if you have any question, please contact us : [e-mail]

[@oldschool240]

And that's why I bought your 12 hole injectors!

[@estebancantu5424]

Thank you so much 😊 it helped my questions

[@jeffmckc2081]

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.

[@by_mo1204]

Thank you !!

[@joeydelmarsjr.646]

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?

[@KSuspension]

Hello, No, the 4port will not spray more fuel than the single port OE units

[@joeydelmarsjr.646]

An OE Bosch 12port unit, not recreation or copy.

The 12 ports looked terrible compared to the 4s. Glad I have the 4 ports now

[@jimlindakauphusman6389]

Ok, so I'm sold on upgrading my injectors! How does one decide on the 4 port vs. the 12 port?

[@jimlindakauphusman6389]

I have a 2004 TJ BTW . . .

[@KSuspension]

4ports for more top end, 12ports for more bottom end, and either choice would be plug n play in your 04 TJ

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!

Definitely a good spray pattern on your 12 port injectors.

[@r.weaver3769]

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.

[@KSuspension]

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.

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.
