Thanks for posting this tutorial! You did a fantastic job!
I'm going to try this for the first time. I was doing research and saw a lot of people recommending dielectric grease.
Should dielectric grease be used on the ceramic part of the spark plugs?

I never have before when replacing spark plugs and never had an issue. There will be an audible tactile click that confirm they’re properly mates. It’s not called for in the FSM, so I’d say no.

The CEL wasnt on when your Honda started running rough? Just curious as my 4runner is getting a slightly rough idle (only when stopped at a red light and in drive), and I am going to change the plugs asap but I had thought that the CEL would come on for sparkplug issues causing rough idle. I do have 126k on it and no sparkplug change that I know of since 51k when I bought it. Sparkplugs first, and if the rough idle continues its time to check other things but it definitely needs new sparkplugs anyway.

completed my sparkplug change out with the guidance of this thread. It went quite quite smoothly, thanks.
The only tip I have is to have some penetrating spray (PB blaster, liquid wrench, etc.) handy. I had just hit 127k on my 4runner (yeah yeah I know I should have changed it out a while ago :rtfm: ) and I started on the rear most passenger side sparkplug and it was TIGHT when I was trying to remove it, it was making the creepy, unsettling creaking binding noise, so I stopped and had a friend bring over some penetrating spray and I sprayed it down in there while I started to work on the next plug. After I got the next coil connector off I went back to trying to unscrew the rear most passenger sparkplug and it broke free with ease, no more creaking or binding. WHEW! Thank you for this writeup. :yo:
Thanks [MENTION=65614]Antman[/MENTION]!!!!!
heres to at least 100k more problem free miles!

Is there a reason for not using it?

I changed my plugs a little early (82k) because I was worried about them seizing if I waited 9 or 10 years.
They are designed to be used without additional anti-seize.
Here's a quote from NGK: "All NGK Spark Plugs are manufactured with a special trivalent Zinc-chromate shell plating
that is designed to prevent both corrosion and seizure to the cylinder head; Thus eliminating the need
for any thread compounds or lubricants.
Additional Information
NGK recommends only using spark plugs with metal plating on all aluminum head applications to
prevent damage to the head and plug. Metal shell plating acts as a “lubricant” which breaks away from
the main body of the spark plug during removal, preventing damage to the spark plug and or threads in
the cylinder head."
I can't find the offical Denso position, looks like the links are broken.

eBay for affordable OEM replacement plugs
Just thought I'd chime in mentioning that searching eBay for 90919-01233 turns up packs of 4 plugs for $16. The eBay images show OEM boxes, and one can see Denso SK16HR11 on images of the plugs. I assume they're authentic. One can buy 8 plugs for $32, which is cheaper than buying 6 individual plugs at ~$7.50 per plug. If you order off of eBay, be mindful to scrutinize the listing to make sure the person didn't just put 90919-01233 in the listing to draw your attention. In other words, look at the listing with a mind toward ensuring you're getting the Denso SK16HR11 plug instead of something different.
Really appreciate your work Antman and Gracie!

Now that Gracie is older, has she shown the Chevy forum how to replace a water pump or a transmission solenoid yet?
:rofl: :target: :behindsofa:
This thread is still the best. :thumb3: Gonna be employing my 7 year old to do this in 2 weeks.
Grace is 9 now and has been helping me frame the basement in. She made me fix 3 studs last week that she said were “out of plums”. Lol.
She knows how to do brakes now too. If I tell her to go and get me a 3/8 drive 10mm deep well socket she (almost) always gets it right!
God help her future husband.

Follow up on eBay SK16HR11 plugs
A week or so ago I posted that I found four packs of SK16HR11 plugs on eBay for cheap. I wanted to follow up on that! I received the 8 plugs I ordered. I found the gaps ranged all over from 0.03" to 0.044". I measured the gaps using one of the coin-style tools found at the counter of many auto parts stores. (I just walked in and used theirs since I'm obviously cheap.) Going off memory from a few days ago, it was either the 2010 4Runner service manual or the Denso spec that said the plugs should be gapped between 1.0 mm and 1.1mm (0.039" to 0.043"). SO...basically I had to gap the plugs to get them in spec.
On a side note, I read all sorts of people state not to gap Iridium plugs, but I didn't read any clear engineering-based reason why. The closest thing I found to a reason was because the Iridium electrode was brittle. Well, these eBay plugs I ordered needed the gap expanded, which was easy to do without touching the Iridium plated electrode. I simply grabbed some needle nose pliers and bent the ground electrode open a tad bit more. I had zero problems getting them gapped to spec.
There's one more consideration with these cheapo eBay plugs that I want to note. The original 4Runner plugs I pulled out had a very small 'dot' of metal on the ground electrode. The 'dot' was directly in line with the center electrode. The dot effectively reduces the gap between the ground and center electrodes when they're directly in line with each other. However, on the cheapo eBay plugs, the dot of metal on the ground electrode was noticeably offset on the center electrode I realized this after I gapped the plugs and then questioned whether I made the gap too big. I installed the plugs anyway and the vehicle runs smooth after a basic test drive.
I'll say the cheapo eBay plugs visually looked identical to the original plugs in all other ways though. The Toyota / Lexus packaging is the cherry on the top that began to convince me the product is legit.
Overall, the point of my follow up is that the eBay plugs might be knock off products though. I don't have much experience with plugs, so I don't know if it's normal to see things like gaps ranging from 0.03" to 0.044" and an odd 'dot' on the ground electrode, which is also offset from the center electrode.
Buyer beware.

Grace should charge $125 / hr for vehicle work
Ohhhh, and I meant to mention that it sounds like Grace is capable enough to begin making money on vehicle maintenance! I'd suggest charging more than the standard'ish $100/hr rate since she's clearly not the average mechanic. Having one's vehicle serviced by a adorable 9 year old deserves a premium!

I remember helping my father when he was working on cars when I was her age.
