Changing Plugs

Post by Stickman » Sat Jan 30, 2016 9:52 pm

So I'm at my 32k maintenance interval on my '12 (at 28k actually though, I change mine every 7k). I just changed my oil and filter, roated the tires, checked the front end components and t case fluid and then greased the front shaft and cleaned the air filter. Planning on doing plugs tomorrow and wanting to see if any of you guys who have done them already have any tips to making it easier. I'm a tall and skinny guy (5'10" & 145lbs.) so I can monkey my arms around in the engine bay pretty good and can reach pretty tight spots since my arms are fairly long and small. I also bought Loctite copper anti-seize to put on the new plugs to prevent any issues later on down the road. Thanks for any help guys!

You change them if you want but they last a lot longer than 30k, I change mine every 60k. I have a 2010, they're not that bad, I actually think the back passenger is the worse though. Can reach them all with straight extension if you don't have a wobbly

I only do what the majority of the 4 voices in my head tell me to. In most cases, I ignore two of them because one doesn't speak English, and I suspect the other is talking to someone else.

I let the dealer do mine because I hate working in tight places.

But like above, they have lasted a long time in the 07 for me and never showed any problems like hard starting, missing or a drop in mileage (lol) when I did decide to have them changed them.

To get the back ones I remove the cover and everything right on top of the engine and right passenger side. I crawl up in the engine bay standing on the right (passenger side) and that works well to get the back ones. It isn't that difficult of a job.

I used a 2 step mini ladder. Socket with a 5 inch extension and a swivel. Took off the hoses and the intake tube on the passenger side. Very easy, did one cylinder at a time. 2 and a half hours total time, with a 15 minute beer break between cylinder banks to let my ribs rest.

Yep, it wasn't too bad, took 3 hours, about an hour and a half per side, passenger rear was definitely the biggest PITA to get to with near zero room to get to it. Drivers side wasn't too bad, just took patience having to put each individual piece (socket, u joint, extensions) in one at a time and then take them out the same way for each plug. Since I'm such a small guy I just sat on the radiator support on the drivers side and the top of the fender on the passenger side with a movers blanket covering everything. Only thing I had to move to help was the intake tube, I just unsanpped the intake tube and lid from the box and wedged it up against the hood to give me some more room on the passenger side.

I was going to wait until 60 or 70k to replace them, but I figured I would just do them now and not have to worry about them for another 50k or so. I don't know if it was just the brand new plugs or maybe just the day, but I did pick up 1 mpg on my instant and average after I took a little drive afterwards. Usually get 12-13 on the highway at 65mph, now I'm getting 13-14, sometimes even 15. We'll see how that averages out but I'm glad I got them done and out of the way. I also replaced them with E3s instead of the NGKs it had, so maybe they helped.

And yes I did actually use all those extensions a few times. Actually could have used 1 or 2 more a couple times aswell.
