changing spark plugs

[Bad1975]

Save yourself some cash and buy them from Toyota online, quick search results ~$26.62 from online Toyota source. These were previously available direct and other sources for cheaper but it looks like Toyota locked that down for now. OEM part is NGK 94644 or DILZKAR8E7H

Previously you could put the Toyota part numbers into the NGK site and it would pull up the NGK part number and specs but this is no longer the case. Strange, reminds me of MOPAR and their lock down on parts for the first 6-7 years of a new vehicle.

Holiday sale 15% and free shipping over $75 purchase national wide Toyota auto parts.
I just bought a set of spark plugs, (and whole bunch of air filters, oil filters, oil) even though my FE only 13K miles. Always, stock spare maintenance stuffs

Our LC spark plug change should be easy.
However, this video can be good education purpose for DIY people

Spoke with Dealer again last week. They wanted $184.XX for a set of 4 Toyota Plugs "90919-A1008". 2 months ago they quoted me $168. When I checked online then
I found warning flags "Does not fit your vehicle" at the sites that carried this size - even after I entered my VIN. Toyota online was sold out.
Last week when I hit 40K miles and got the dealer price, I checked toyota.com again and they were in stock $129 shipped. Just got them today.
They came in the red/white Toyota box marked 90919-A1008, but they are NGK DILZKAR8E7H.

Good deal. It’s stupid easy to change these out and i’m coming from a 3rd gen 4Runner. I just get the parts at my dealership.

I changed them on my 2024 58 today.
It took about an hour and a half.
Only because I had to go dig up my torque wrench and then find a flexible magnetic pickup tool and then jury-rig several shorter 1/4 & 3/8 socket extensions together as my 24” extension bar was too long for the back 2 plugs and my simple 6” bar was too short for all the plugs.
You will need a magnetic pick up tool to pull the plugs out of the deep-well plug tubes as well as to reinsert new ones without dropping them into the plug hole. I noticed after 40,000 miles, the gap was worn a little bit wider in the old plusgs vs the new pre-gapped plugs.
I saved my old plugs in the event I ever need them. I imagine the next time it will go much quicker because I know what I need now., including a small stepstool. I’m 6 foot and it’s still a bit of a reach.

Use this magnetic socket

Probably not what you had in mind, but you can make some nifty glass-break tools out of them.

Anyone know where I could order them?

If you plan on pulling your plugs to "check them" you should have a new set handy. First, you're not supposed to reinsert a spark plug without replacing the crush washer (i know, i know, we've all done it), and second, if you damage an insulator etc, youre sol until you aquire new plugs. Typically, only time you NEED to check plugs is when you're tuning, or have changed tuning of an engine.
Replace all of them at recommended intervals with pre-gapped OEM and forget about it. (Blow out the plug tubes before removal)
I use a sliver of neverseize even though is not recommended typically. If youve ever had to remove a seized spark plug, you now use neverseize on everything.

Thanks for the tips, I've never swapped plugs before and i don't want to miss anything when i try it. Regarding the crush washer that should be replaced, do they come with the new spark plugs or do i need to buy those separately? if so, is there a part number or size i need to get? BTW, im taking notes from all these comments and building a parts and tool list. TIA

Spark plugs have the crush washer made on to them, so they’re included.

May want to get (4) 11193-F0010 Spark Plug Tube Seals. When you remove a coil pack (off of the valve cover) for each spark plug there is a rubber seal on the coil for each spark plug tube.

Just ordered.. it’ll be here tomorrow..

I spent thirty minutes looking, and only found one value..

Spark plug gap???

.032”???

 

[Bad1975]

Page 634 in the owners manual.

Make NGK DILZKAR8E7H
Gap 0.028 in. (0.7 mm)

Check do not adjust noted in the manual (they come pre-gapped, never received an Iridium pre-gapped plug not gapped to spec), can be adjusted but don't adjust via tip to ground or you'll likely damage the iridium tip.

Equally important, I only check the gap with feeler gauges or my old school gap pliers with built in gauge and not a traditional cheapo spark plug gap tool as it's easy to flat spot the tip on these. If really worried use .027" (easy fit) as a go gauge and .029 as a no-go gauge (shouldn't fit), then you know they are at spec and no damage is possible when checking, same manner as adjusting valves.

Sometimes imadufus.

That’ll teach me to use Duck Duck Go!

Yea, I just wanted to check, to be sure, before installing them.

Thank you very much for that!!!

The Torque Test Channel did a nice video about counterfeit spark plugs and found that the Amazon plugs were likely dupes. Buyer beware...

 

[Bad1975]

Scamazon and Fleabay are known sources of counterfeit Toyota, Denso and Aisin parts, I'd steer clear of those places for electronic items for vehicles.

If you can't buy from Toyota, manufacturer for Toyota, a reputable brick and mortar auto parts store or places like Summit avoid them. This goes for everything Ignition wise and pretty much any sensor on the vehicle.

It absolutely amazes me how many people might read this thread or the thousands of post on FB or other forums and still order the parts anyway.
Car Care nut has done some cool videos showing differences in a lot of parts. Also troubleshooting videos based on aftermarket or counter fit parts.
