4.0 v6 1gr-fe spark plug change instructions
 
This is the best write up I have found for changing the spark plugs on this engine. I hope it helps.

Yes, this is very clear.

I find there are fewer items to remove for the 4runner v-6:

It is sufficient to just unclip the intake at the filter access and swing it away to access the passenger side plugs.

For the driver's side plugs, the upper bracket bolt needs to be removed and the lower bolt loosened. No harness clip or hose needs to be removed as shown.

Replace the sparkplugs every 30K miles? I thought they last longer than that. I don't remember the #.

The V8's change interval is at 100k. The V6 is at 30k.

How to video - change spark pkugs
 
How to change spark plugs - Toyota 4Runner 2006 - YouTube

Watch this before taking your 4runner to the dealer and save yourself some money!

A quick and simple video I shot while changing the spark plugs on my 2006 Toyota 4runner, Sport Edition, V6.

This should apply to 2003-2009 4runners and most Tacoma trucks (same years, I think).

Its pretty simple to do, with the right tools and an hour or two, you can save yourself some cash.

Enjoy!

Thanks RGates. Just the video I needed.

Know this is an old post, but it was most helpful to me. I have changed a lot of plugs, but have learned at my age that even tho I can feel my way through a new project, it saves time and headaches to learn from others before starting,

This is a great instruction.... very helpful. I would definitely advise getting a secure attachment on the extension and plug. I lost one in another vehicle some time ago and had the dickens of time getting it out...

5th Gen change spark plugs - EASY
 
I know this is an old thread. But thinking this may help for first group of 5th Gen consumer :-)

I just changed all 6 spark plugs on my 2010 4runner limited (1st year 5th Gen I believe). You may now can find some video on youtube to guide you to do so. But someone ask you to take out entire air intake compartment.

It's actually not that complicated.

I can confirm here, you don't need to remove anything to get the job done. Passenger side is very easy. Take it as an hands-on training course. you will be professional by the time when you finish the passenger side.

It is trickier on driver's side, especially the inner one. But IT CAN BE DONE without removing any compartment.

Unplug the electrical cable actually is the hardest part. I use a tiny screw driver to help myself. You also want to make sure you do not drop any bolts, small tools, etc, under the hood.

Cheers,

Sorry for prolonging the necro-post, but does anyone know the specific reason for 30k on the v6? If I have double plats it seems like they should last quite a bit longer than that? Is the factory spark plug a copper plug or something?

That's correct. V6 plugs are copper.
V8 plugs are laser iridium

I went on RockAuto and they have NGK Iridium plugs that are supposed to be compatible with the 4th gen V6. Everything I've heard about NGK Iridium is that they are high quality and last a long time.

So would using them extend the interval, or should plugs still be changed out after 30k miles?

Iridium plugs should last until around 100k I think. On the 4th gen V6, regular copper plugs are called for and the change interval is 30k. I always just get a pack of Denso's from the parts counter at tmy local dealer. I've had bad luck trying to "upgrade" to better plugs and the vehicle ran poorly. Switched back to standard plugs and no more issues. I've only ever used regular plugs with my 4runner so I can't comment on any advantage to iridium plugs. I would just stick with what it's designed for. Changing the plugs is very easy.
