My Jeep’s 4.0 Was Turning Into A Gas Hog! K Suspension 12 Hole Injector Install 

No need to apologize for the kid. I always enjoy seeing the whole family getting involved in the Jeep thing with Dad!

When I saw your little girl I smiled and thought it was cool. My little girl was with me while I was removing distributor cables today.

Replacement injector plugs for a Dodge Neon make excellent Replacements for the 99-01 jeep electrical injector plugs, they are heavier built, simpler and easier to use.

Even while upgrading other engines to multiport injectors, Chrysler used the single port till 2001 in the Cherokee .... most of the forums warn against using the cheap chinese ones ... Bosch are considered the best OEM, but there's a guy in Cali that rebuilds Bosch 4 port for half the price of new ones .... I'm sure the K Suspension 12 ports are good quality ... I did the Bosch 4 port and it smoothed out idle, better gas mileage .. my old ones were OEM with 260k on them ... the platic crumbled in my hand as I removed ... lol

Just finished my coil pack and injectors Jeep runs awesome what a great upgrade

To everyone wondering, the discount code IS still active ! Just bought some 4 hole injectors for like $100 flat. Hopefully I’ll remember to come back to this comment and give an update for those who are on the fence like I was before I took the leap

Great to see family

One thing ive learned along the way. Wives dont give a crap about jeep life, tranny service or starting issues. All mine cares about is, how much money this time and dont get stuck. LOL. Great vid!

Never be sorry for showing your family. Thanks to you i got these injectors ordered from raffi. Thanks for the code! Love ur content so i subbed too!

Thanks for this video!

The 2 year old was the high point!! I'm planning the same upgrade on my 1995 E-150 5.8 Liter W (351W) . In Canada gas is now at about $6.50 a US gallon. My 4 hole injectors are in the mail right now. Getting just under 14 MPG now. Travelled across North America in our modified Van. I hope to see a mileage upgrade. New timing gears and chain already. Thanks for the moral boost.

Great vid. Been doing a little research on injectors for the jeep 4.0 I have an 02 Grand Cherokee with the 4.0, 4" RC lift and 33s. Starts fine, idles good, but looking to improve on the 10 - 11 mpg. It has 130k miles and should be good for that many more. Thanks for the vid! 👍✌🇺🇸

I've been running the 12 hole injectors for about 2 years with no issues. Great upgrade. And Raffi is a great guy.

A bit of silicone grease on those "O" rings makes'm slicker than snot and way easy to slide into the port.

Nice! I’m about to order a set! What fluid did you use in your transmission? Mine is feeling a bit notched in 2h. 4h and 4l feels fine. I’m wondering if I need a new slave or if it’s something simple like the fluid type. Right now it’s full of royal purple

So these will be plenty for my 4.7l stroker? It's got a ported intake and throttle body out to 62mm. Was also looking into the denso 12 hole ones and just can't decide yet. The denso shows more volume during the test I've seen

When I did the injectors on my ZJ I got better gas mileage, more power, I actually had engine braking liek a tractor instead of just rolling down hills liek I was in neutral in 4 low. I swear Chrysler just put the worse fuel injectors on the Jeeps. Literally garbage injectors from the factory pre 99. I literally pulled scrap yard injectors off a mustang and they were only 17# injectors and fixed everything. Night and day difference. Of course I went back and got some higher flow injectors at a later date off a 2011 crown vic Police Commander. I did clean all my injectors to. My ZJ gets 25 highway miles now. I also put better spark plugs and a performance ignition coil to help burn the fuel better.

K suspension is right around the corner from me!

The first long start there was def a lesson in let the rail prime first when she's been emptied. Do you know what brand the injectors are? I see so many Chinesiums on eBay ive been to scared to risk.

I installed the same on mine the groove for the clips didn't fit tho and if I would have Installed it like you did it woold sit loose in the rail so I just put em in without the clips guess it's fine not sure tho.....

what fluid you using for the ax15 ?

I just got off the phone with K suspension. Mine should be on the way in a week or two.

8 mpg jesus.... My bone stock 01 WJ with 215K on ODO does 17 mpg in town, and 23-25 on the highway

I'm running 100% stock 2000 Wj grand Cherokee 4.0 single hole injectors. I'm looking to get it emissions deleted but till then do you think a 4 hole upgrade or a set of 12 hole injectors would be better? In the future I plan on leveling it and putting stock size ATs on it

Awesome video.. Do you have any tips to cure Death Wobble..? Scariest thing I have ever experienced.. I'm trying to get over the fear of Encountering Death Wobble.. lol..

Great family - your blessed and gotz Jeeps too -

What number of reference of inyectors?

Hey boss, what is the order number of those injectors and are they remanufactured? I see on their site that they offer remanufactured injectors I do not want those. I want the plug and play ones like you got.

Very interested in doing this My Jeep is a 05 TJ 195000 miles Might be time?? What part of Arizona are you in

How's the fuel economy doing these days? I had a '98 ZJ with the 4.0 which was averaging 18-20 MPG when I sold her.

I kid you not, I've had mine for a month longer than you. City driving, 15.5mpg., highway 17.2mpg. I also have the "viper" coil pack modification.

Quick question! Did you remove that clear plastic cap looking thing on the manifold end of the injectors or are they supposed to stay on?

What does reset of ECM??? means. how did you do that?

Nobody ever says what their mpg increase was in these videos...

8mpg......good lord!!!!! A ford 460cc, is literally twice the engine....and gets better mpg.

Is that an IDAHO shirt
