I've gotten 16.4 miles to the gallon in my 2002 jeep Grand Cherokee Laredo 4×4 4.0l6 by using synthetic oil, tripple platinum spark plugs and wires, clean the throttle body and replace the front brake calipers rotors and pads because someone didn't have a clue about doing brakes so I was getting around 10 miles to the gallon because of the dragging of the brakes but All Is great 4 inch lift 33 ×12.5 tires on R17 and I'm happy with the gas mileage power. and I'm going to do that mod for sure so thanks again for Another Great Video
I dont feel so bad now getting 16+ mpg. I did just put a new motor in 5k mils ago. I had the bottom of piston 6 explode on the highway. Still made it home 50mils away lol cant go wrong with the inline 6. Also, it only exploded because i got the jeep from my dad, he believes oil changes are a scam. Still lasted 176k miles with maybe two oil changes before i got to it.
Just put mine in the WJ this morning. You're right, it's an easy upgrade even for a novice. Your video made it even easier. Thank for the instruction and also for the idea in the first place! My ignition rail was starting to have interment misfire problems. Seems to be good to go now! Thanks again bro!
I used to get 14 mpg then I got a faulty 02sensor in bank 1 so I changed that and now I’ve reached 16.6 average. I’ve watched a video of a few upgrades done on the 4.0 and this resin has managed to average his 2004 grandcherooke to 22mpg which are incredible numbers for thee 😅
I put one of these on my 2000 WJ about a month ago and love it. Changed plugs at the same time and getting 18.5 to 19 mpg. they also make a wiring upgrade kit that' s pretty awsome , Put that in about a week ago.
I love how simple it is to install! I was going to change my plugs out but I wanted to isolate it and see if any difference happens then I’ll change out the spark plugs in a week or two
I just did this this morning. I couldn’t get the plug off so I went Sasquatch on it! I broke the connector off of the bar, since I knew, never going to use it again, and disconnected it from there. It was much easier. LOL
I’m looking at one of these kits And the biggest complaint on the reviews that it does not come with any instructions and with your video instructions aren’t needed.. thanks so much for posting.
I have a 99 Jeep Grand Cherokee and ordered the bracket and wire harness. I did not get the coil because I have a few coils for my 2000 dodge grand caravan with the 3.3 liter engine . I found out that you need a specific year for it to work. You need one from a 2001 to 2010 grand caravan and also the Dodge Viper 1997 to 2006 will work. Went and got the proper coil for it and will install and see if it runs
Just did this on my 04 tonight. Your video helped a lot. Thanks. Not sure if your came with it or not but mine has a bracket for the top part mounted to front hole of old rail and a nut and bolt attached to the plate. Thanks Najar for the video.
Your videos are great bro! Super easy to follow. My lady has a 2000 grand and Im about to tackle all the needed upgrades. Def gonna check this one now after watching this video. Super stoked on your channel
@@NajarOffroad thats what Im learning. its different from my 1989 suburban build, but it seems just as friendly. Been staying up late watching videos. ready to attack and modify!! cheers!
Another banger! How am I just seeing this one? I have the misfit 1999 WJ so finding anything other than stock coils is impossible. I'm about to try an MSD with NGK type adapter. 25 years on the original coil. Its time...
I ordered the viper coil pack for my 04 wj. I hooked up the firing order how you had explained and it wouldn't start. I had to switch 4 with 6 and 1 with 3 and now it seems to run fine.
The old style coil pack is also susceptible to oil leak from the valve cover and heat from being directly connected to the engine, this mod will definitely help with the oh-so-fun to trace intermittent misfires. Probably do this on mine once the new lifters and head gasket are installed, also debating doing the washer an coolant jug swap and putting in a second battery for accessories.
What’s up man! New subscriber! I’ve used your videos to install my headunit and backup camera! Love your enthusiasm for your truck I got the same year I believe 04 right? After watching this, I went ahead and ordered from KSuspensionFab keep it up!
Excellent video! Thank You for making this. Always nice to see others making some content! Shoot us an email with your order # when you get a chance! 😎
When my coil pack failed it showed up on the scanner as an evap leak. One smoke test later and no results. Changed the coil pack and I got a leak detection pump code. Changed that. Evap leak code again. Viper coil pack cleared everything. Chrysler pcms are a pain in the ass.
sorry about your gas millage my wj 4.0 has 2 1/2 inch spring and shock lift 31 inch tires otherwise stock it gets 25 on the highway 60mph and 23 at country road speed 45 mph 1.500 rpm. Back and forth to the house gravel road 2 miles i average 19 mpg no real off roading .
I am from Iraq. I need your help. He has a problem with the 2001 Jeep Cherokee. The 6-cylinder engine has the first, second, fifth, and sixth cylinders. The third and fourth does not work with the presence of spark, fuel, and pressure.
My 4.7 ho gets about 25 on hwy .... 20 combined ..... and 16 in town. I ditched the hydraulic fan and put in a machanical 12 blade fan from Ford ranger. Everything els is stock
And what’s the new mileage with the viper coil?? I’m getting 11.6 with a beater that’s been stored for a few years and it’s on shitty 31” tires with a3” lift
Why am I the only person on the planet that this does not work for? 04 WJ, now getting a p0351 misfire on coil 1 circuit. 🤦Jeep runs like shit now. Even changed spark plugs to OEM. Works wonders for everyone else tho! Go figure!
You mention firing order a few times in the video - the firing order on a 4.0 is 1-5-3-6-2-4. You said 1-2-3-4-5-6; that's the order of the cylinders front-to-back. It looks like the coil pack handles the firing order internally, so not a big deal functionally as you gave the most important info in the video: which spark plug goes to which post on the coil pack. Just FYI.
Just ordered, wouldn't have known about it If not for your channel 👍 I think I've done every upgrade imaginable to mine. But THIS is the one thing that's always been problematic! Did you install the standard model? There's an upgraded model but I personally just went with the standard one.
@@NajarOffroad damn I bought the kit like 2 yrs ago and haven't put it in yet. lol don't judge me. Was hoping it would help. I also just got injectors. I'm going to do it tomorrow and see.
I just ordered the Viper Mod And Now With The Original I'm Getting 12 Miles City And 17 Miles Per Gallon Highway, I Believe That's Factory Milage Per Gallon So I Hope I Get Better Gas Milage Even 1 Or 2 Milage A Gallon More Would Be Great,It's Been A While Since You Changed Yours, Are You Getting Better Gas Milage With The Viper Mod? I Have Tripple Platinum Spark Plugs,Very Expensive But I Like Them,No Hesitation, Smooth Engine,So I Hope The Viper Mod Does Me Good lol

Got a 99 4.0 but it has this insane missfire at idle until its warm and its also at 800-2200 rpm than it takes off but it hits limp mode when you slow down gotta restart at every light the mechanics look at me completely puzzled everything is new pcm plugs coil sensors no cat it changes nothing so anyone want a 4.0? 200k miles 0 leaks its ansuper strong motor its a 99 and has the extra thick walls outside of the insane missfires like super crazy it runs great
@@trevorthomas6043 checked that already. The problem at first was just that after i drove to a store for example when i started it it would be in limp mode i had to restart it to get it out of that it did that for months before just dying after it got hot wich was about 15 mins of driving then instead of dying it would missfire then it started up misfiring at idle goes away after about 3 mins but still misfires at 800-2300 rpm 2400+ no missfires wich is were i am now.
Yoooo I’m trying to pick up a WJ everything around me is $3-8k with like 150-200k+ miles. What price range should I be looking for? Is it even worth it to get one rn?

Just upgraded my WJ with this kit. And used the video and the code for discount.
What discount code?

hmm wonder what happened there. mine has been running fine
I get 15mpg in my 04 wj, it has the 4.0l with a misfire at low rpm. Should do something.
thanks for this video i did this upgrade today, well worth it
10.8 mpg😲, my GC 4.0 is on 35s and stock gears i get about 16mpg but I'm in a rural area not far from denver, not a tone of stop and go.
Wow 😂 I’m getting jipped by my Jeep
@@NajarOffroad bruh I just calculated mine and I'm getting 18.5 mpg, help lol
The old style coil pack is also susceptible to oil leak from the valve cover and heat from being directly connected to the engine, this mod will definitely help with the oh-so-fun to trace intermittent misfires.
