Boy i miss the days of not having to remove anything to change the plugs.Great video never realized so much involved in just changing plugs.

[@bob-a-louannamaria7960]

So you also miss the days of poor performance, smelly exhaust, noisy (not the good sounding) engines. Bad gas mileage, over heating problems, crank windows, no A/C, sloppy suspensions, and all the other shit technology that’s been improved upon over the years??

[@redstang006]

@@bob-a-louannamaria7960 guess you weren’t around back then.If you were you would know how ridiculous you sound.Performance was top notch just look at where muscle cars came from,Smelly exhaust and noisy are you for real?Not sounding good…lmao they were better sounding than today cars.The rest of what you said is just laughable.

I just changed the spark plugs and coil packs. The whole set hadn’t been changed since the motor had 0 miles . 170000 miles later after I did the tune up there was a huge difference in performance. Thanks for the video it helped so much.

Awesome step by step instructions, keep the DYI videos coming Brotha!

I have learned a lot from this guy with my Jeep journey. Keep going with the great videos.

[@dennisl6198]

i did this today, and the video was helpful in helping me to make sure i didn't miss anything,. as for re-securing the intake, I used a 1/4 screwdriver style tool with the 8mm ratchet, and just made everything hand- tight.

[@billellis2413]

Thanks for posting the video - I've changed plugs on the 3.8 (pretty simple) but first go at the 3.6 and saw they were under the manifold on the right side so appreciate all of the tips.

[@GametimeSlime]

Where are the ones on the 3.8

[@xzysyndrome]

"Hopefully, It starts..." Spoken like a true do it yourselfer. I changed the plugs/upper plenum gaskets on my JK last night...what an adult vocabulary workout. I've changed the plugs on all my vehicles...but this was by far the most involved. Good news is, it started right up...bad news is, I wasn't aware that there was a tightening sequence on the upper intake bolts and believe I cracked the lower intake, as there is now what sounds like a vacuum leak...which means I get to do this all over again...and then some. Protip: Know the tightening sequence and do NOT exceed 7lbs torque....the lower intake is plastic, and WILL crack. Buh bye another $200.

[@adventuredex]

Thanks for sharing

[@atanasiobustos9793]

Or over torque and break the head off the front bolt for the lower manifold... ugh

[@mustseevideos7777]

How do I find out if there is a sequence to follow and the recomended torch? I have a 2014 Jeep Grand Cherokee Limited 3.6l 6cyl.

[@jimjab3631]

Really nice job man., nice jeep also. I put mine in the shop... new sensor and plugs. I just get zero pleasure working on cars, just too cramped and frustrating

Thanks Christopher! A full video on the K1 is in the making! Stay tuned

[@robertware8643]

They added so much housing I like the coil packs though much easier to do than the plugs and distributor cap.

[@garymounts8285]

Look I know this was really great video and very informative. Might want to mention to check your gap on your spark plugs I know that they are supposed to come pre-gapped but it is not always the case.

[@jeremymiles8021]

Did you use anti seize? Thx for the video.

[@armedprophet3321]

Hey man !!! Thanks so much, I actually was watching your video and copying what you were doing on my wife’s Jeep JK. She is so emotional about her Jeep and she called me from work and was freaking out about her Jeep having some long crank issues and demanded I change her plugs. It took me 3 hours and a lot of patience and bravery as I didn’t want to mess anything up by doing such a dismantling. But it worked out ! I actually prayed to God that he would help me not to break any plastic clips or lose anything where I couldn’t get it, and to help me do a good job. I have worked on a lot of cars and trucks in the past with no issues but today’s engine bays are packed so tight that you got to remove 3 things just to get to what is broken. Anyway thanks again. I just subscribed and thumbs up.

[@adventuredex]

Thanks Jay!!!! Love it when it all works out!! 🙌🏼🙌🏼🙌🏼

[@maxeyac]

I prayed too... 🤣

[@robertknull456]

Is it always necessary to replace the intake gaskets? Thx for the vid!

[@Txwag91]

2014 Jeep Wrangler Rubicon. 67K took in for DTC P0306, but it was covered under warranty because of the #2 Cylinder was showing issues as well. That was 2019. Now, I'm just shy of 150K and getting a P0305 and P0205 DTC. Going to be changing the Spark plugs and Fuel Injectors myself.

[@robertware8643]

Great video

[@ROgletree]

Good video. I have 165k on my original plugs. I just ordered new plugs, wires and coil pack. Lately it occasionally won’t fire right away so I hope that’s all it needs.

[@adventuredex]

That’s awesome Richard! Yah am sure it just needs new plugs

[@bgnewland]

My future son-in-law and I did this in 3hrs today. I thought for first timers it was a good time. He’s 17. I have a 2016 unlimited sport. There was a bracket between the battery and the manifold w 4-10 bolts we had to remove that attached to the side of the manifold. Other than that it was straight forward. We tackled the passenger side first and I think that is easier, because the manifold is scary. If you change those 3, u can’t look back. I recommend a long and medium socket extension and you may need both size socket sets. There are some brackets and retainer walls that make a couple coils and plugs hard to get too. We only had the long extension for the plugs. It was a fun experience and big confidence booster for both of us. Purring like a kitten and no codes 💪🏻

[@herefordvalleyhomestead6125]

Just did the oil cooler, lower and upper manifold gaskets and spark plugs on my wife’s 14’. Man it runs so much better now.

[@hoselrocket2001]

I was thinking that I met as well swap out the oil cooler while the intake manifold is off - and replace with an aluminum Dorman part since we know it's just a matter of time before the plastic OE part starts leaking. So plugs, gaskets, and oil cooler make sense to do at same time. I have 55K on my JK.

[@tomc8157]

Maybe..but most of the stuff thats a royal pain in ass to change, your not doing weekly or monthly. So once every few years isn't a big deal to me.

[@jonathantynes3781]

Question did you replace the gasket or did you reuse the old one?

[@ZachDames]

Keep in mind, that even though Irridium spark plugs (like from NGK) say they are pre-gapped, always check each spark plug. Human error occurs and you will commonly find spark plugs that need to be adjusted.

@AdventureDex is the spark plug change the same as the JL model?

[@bobbyc7196]

Cool stuff!

[@adventuredex]

🙌🏼🙌🏼🙌🏼

[@sector783]

Great video. Thank you!! So, I just purchased a 2016 jeep wrangler sport four-door manual trans. Check engine light came on six hours after purchase. We got a cylinder two misfire detected which can apparently be one of three things. One ignition coil. To intake gasket or three and probably most common, spark plugs. I am just a beginner, so can anyone second the statement? Is this correct? Also, when I took it back to the dealers mechanic he said she would replace the spark plugs and ignition coil and that it would take over three hours of labor costing me $309. On top of about another $190 for the parts. So after tax this job is taking this mechanic three hours and charging me 500 bucks after taxes. Is this a good deal? Fair deal? Or rip off? Why or why not? Thank you guys so much!! 👊

[@allisself8819]

Thanks 🙏

Hey man what year is that Jeep

[@TheJaciad2]

Are you completely missing the bracket on the left side of the manifold? On my '14, there is a bracket with two screws that completely prevent you from removing the plenum that easily. I ended up having to loosen up the back right bracket on the bottom and remove the front bracket all together. Random aside for all of the people saying you need to check the gap, if you are using iridium plugs, you don't mess with it because you can break the diode. Overall, good video that highlights the big points.

Helpful tip if anyone notices a little bit of oil down by the spark plug it’s because the plug gasket is failing and should be replaced. Adds another 2hrs to project.

Please share spark plug detail?

[@tdz69]

I changed my plugs at 60k miles. Mainly because the oil cooler housing shit the bed and while the engine was apart I figured may as well change the plugs. Now I’m at 110k and probably going to change the oil cooler housing AGAIN just as preventative maintenance seeing as I only got 60k out of the first one. Spark plug change is coming as well as PCV valve change. Hate these engines. Lol

How come nobody ever gaps their sparkplugs in any of the videos online? I've been trying to find the specs for a 2016 trailhawk

[@pohl218]

The author prep this before the video. I just did it after watching and it took me 2.5 hours. He doesn’t mention how many zip ties you have to cut and there is an extra hose on the driver side that is hard to remove from the manifold. Then there’s the bracket on the passenger with the big wiring plug that has to be removed. Overall good video bro. Thanks.

[@Thehandler85]

Well, obviously he can’t make a 2.5 hour video. He showed exactly what you need to remove. The rest of the easy stuff is on you.
