Wife just got a 14 sr5. The plug coils look like they're a real PITA to get to. Anyone try this yet? Just trying to learn a little about the new ride.
Thx in advance!

Yea the AIP valves are totally in the way, and will make changing them out a real PITA. Luckily us '13 and '14 owners have 100k miles before we have to worry about changing them.
At some point, I was just going to get a TIS subscription for a day so I can get the updated procedure for this.
I don't think anyone has put enough miles on their '13 or '14 to change sparkplugs yet.
My thread on the AIP details all of the AIP junk that blocks the spark plugs.

On a side note, my AIP has started to make a "Pop" sound when it does that reverse blower thing (Wwwhhheeeeeeeeeewwwww-POP!) when you shut off the 4runner. I have a feeling my AIP system will fail before I need to swap out my spark plugs.

Planning on changing every oil change?
Statistically speaking most people won't have bought a new 4Runner and ever need to change their plugs. Most people trade in or trade up before 100k. If your one of the lucky one that make it that far then 1 change that's a PITA to get to 200k miles isn't that big a deal.

at least, my guess is that as a community, someone will find the best way to do this ourselves, and share it down here. For example, the oil change thread of Antman, without it my first oil change would have taken 4X the time it actually took.
Edit: Looks like we will have to buy 2 gaskets for the air injection pump, 1 for each side valves (if both sides needs to be removed). Then it looks like removal is 4 nuts per sides, 2 collars holding the rubber hose, and 2 screws holding the metal pipe from each of both valves to the exhaust.

For what it's worth, I changed plugs on a 2GR-FE engine('06 Avalon) at 162K. The plugs had no wear whatsoever. As far as I'm concerned, they could have gone on indefinitely.
3 months later I changed the serpentine belt on same vehicle. Once off I could see no wear. Yes I know - hard to believe, but that's how it was.
I think it might be awhile before you need to worry about plugs. Fluids and filter changes will get these vehicles down the road for some time to come.
People hitting trails may have to deal with some areas sooner.

did you measure the gap? was it still within range?

I verified the gap on all 6 plugs before starting. The factory service manual called for a gap between 0.039 - 0.043
For all 6 plugs, a 0.042 gauge would clear; a 0.044 would not, so I knew I was within range.
Keep in mind these measurements may not be right for your 4 Runner. They are for the vehicle mentioned above.

Old thread but figured I'd post here. Just completed a spark plug change on my 2014 with 72000 miles and it wasn't as bad as I thought. To remove the air pump all you have to do is unplug the connector at the top,take off the 3 12mm nuts that hold the pump to the valve cover, and remove the 2 10mm bolts from the pipe on the side of the pump that runs down twoards the exhaust manifold. Once you do that the pump can be removed from the studs and you can access the spark plugs. just be aware that there is a metal gasket on the flange for te pipe that goes down twoards the exhaust manifold. The gaskets just kind clip onto the flange so no need to worry about them falling off when taking off the pump. Just make sure they are there when putting everything back together. i didn't remove any hoses from the pump itself becasue I had enough slack where I could move the pump to the side.
the spark plugs are iridium . these will require replacing maybe 150K miles of normal use. I know some that go 200K miles.
iridium metal can take the heat a great spark plug compared to what was available back in the old days.

[MENTION=48186]cougar428[/MENTION] did you happen to measure the gap on the old plugs? Curious how close to gap was to the limit. Thanks.

Sorry for the very late reply but I haven't logged in for a while. Unfortunately I didnt measure the gap but the plugs still looked good and had a golden brown color when I pulled them
