Just did mine yesterday, I was a little worried about last plug on passenger side but actually it wasnt that bad for me ... I used: Spark plug socket + 6 in extension + two pivot flex socket + 10 in extension + ratchet ... It was very comfortable and easy ... just make sure you dont put that whole kit together and try to shove it in i had half together for the hand tightening of the plug then connected the rest.

The middle plug on the passenger side was a pain though... there was a bracket with the oil dipstick and some other flex soft hose with a cap that i didnt know what it did... I though the middle one was tougher than the last one to be honest ... Thanks for the post though... the pics helped a bunch...

Just got done with mine and had the same exact thoughts as Jonathan... thanks as well for the post and the pics!



Edit: I should probably add that I needed to use a long extension on my screwdriver in order to remove the two star screws underneath the airbox.

Great write up, thanks! I have one tip: I used a 2" and a 9" extension for the back left (when looking at the engine) spark plug. I put the spark plug socket with a 9" extension in first then attached the wrench with the 2" extension. I was much easier to manage than using a 11".

I think I did mine the same but with a swivel on it.

Excellent instructions!!!

I have done this twice now since my wife and I both own 2008 Jeeps and this thread helped immensely! First time, took just over 2 hours, second time 1 and a half from start to clean up. I also started with the back, left plug and removed the transmission bracket slightly to the side each time... not too bad at all. By the way, the hex star screws for the air filter took a T27 on ours

My "problem" was getting the coil packs unmounted. I got a 2010 and I've got three of these(I know it says 4.7L)


The mounting bracket holds an anchor with a screw in it. Found out you just gotta get a big flat head screwdriver in between the anchor and the anchor hole on the engine and pry it out.

Putting it back in is just taking the screwdriver and tapping the top of the anchor so it'll pop back in the anchor hole.
