Jeep JK Pentastar Spark Plug DIY

Jeep JK Pentastar Spark Plug DIY

Replacing spark plugs on a Jeep JK 2012+ with the new Pentastar V6 is not as straight forward as you may think. This video goes over the details you need to know along with torque specs and how to remove the upper intake manifold.

In this video I used the following parts:
Champion RER8ZWYCB4 (9704) Spark Plugs (x6 required)
05184562AC – Intake Manifold Gasket Upper (x6 required)

Recommended tools:
Good spark plug socket
1/4″ metric sockets
1/4″ extensions
1/4″ ratchet (preferably flex head)
3/8″ metric sockets
3/8″ extensions
3/8″ ratchet (preferably flex head)
Micrometer torque wrench

Stephen Lacroix says:

What is the correct part number for the gasket set?

tactical_baba says:

FYI, (Fall 2017) In Austin, TX shop, I was quote $260 for this job. Includes spark plugs, not new gaskets.

MARTIN WOOLDRIDGE says:

You don't need to change spark plugs until 100,000 miles. Use OEM plugs do not use high tech plugs like E3

MARTIN WOOLDRIDGE says:

A straight six would be better but not like the old 4.0 jeep motor. More like BMW high tech turbo straight six.

Great tutorial and thanks for the part numbers for the gasket. Cheers mate. Well done!

Steve Dykes says:

What would you estimate the total time was for you to do this job?

weldingblaster1 says:

You don't use anti-seize on the plugs or electrical grease in the plug boots before reinstall?  Thanks for the video though, it is very helpful!

vzwflipshot says:

This was helpful. Thank you!

SCDolphin0 says:

Helpful but wished lighting was better

tonepaw says:

What about champion iridiums?

Shane Richardson says:

Great video, good detail. Not looking forward to this when the 4.0 was so simple.

Have you noticed any changes in engine noise without the insulation?

Andrew Thomas says:

Great video on changing the spark plugs. Must have ben a bunch of drunk engineers that put the spark plugs under the intake manifold.  One question: I noticed that the last component you removed prior to removing the Plenum was  the electronic throttle body plug.  I didn't see you reconnect it when you first reassembled the plenum after installing the left side plugs.   I am assuming that was the first component that was reattached for reassembly?    

Thanks
Andrew

Jeff Iannotti says:

Thank you! Although i had to go farther to replace the oil pressure sensor (had to also remove the lower intake and fuel rail) this got me most of the way there, much appreciated!

Ralph der Kapitaen says:

do you use some workshop manual with all the details? I wonder, as you stated all the different torques on each bolt..where did you find the torque info? Thanks

Chuck says:

you are awesome, great detail, really appreciate it,. more on Jeep Wranglers , we trust you

Alan Davis says:

OK, so I just did this myself, followed your video and I thought I'd add a couple things. Electric connectors – I f#$king hate them and everytime I encounter one I feel like I'm in the Da Vinci Code – you skipped through the connector under the throttle body, I. could not figure out how to unclip it, I think I may have even broke off one of the tabs, I did figure out it's possible to leave it connected and just flip the plenum over and out of the way with it still on. It would be helpful if you showed us exactly how to disconnect those wicked things. Also that steel bracket on the passenger side valve cover is a PITA – I sure wish it was easier to remove but you have to take out the battery box to do so. What I did discover is on the driver side there are those 4 nuts that come out of the plenum sideways. The bracket that connects to the two in front near the throttle body can be completely removed via two 10mm bolts under the throttle body – it's makes wrestling the plenum off a whole lot easier! Thanks for your video!

I really don't want to do this lol, but does anyone know which side cylinder 6 is located on?

alan jackson says:

That foam insulator wasn't falling apart, it was being chewed on my rodents.

Neomarie Massa says:

how many miles on the jeep for a spark plug change?

Juan G says:

did you find out how much a mechanical shop would charge you for doing this job? .. and thanks man, it was a very helpful video..

Adolph Runsick says:

Let me put in my two cent about the foam. An engine run better and is more efficient when it runs on cooler air. Now that you have opt out of replacing the foam you have allowed the heat for that side of the engine to heat up the bottom side of the air box. You have increased the temperature of the air that your engine has to run on now.
