Glad I didnt wait

Decided to change out the spark plugs today on my 13Taco, 95,000 miles. Boy am I glad I did. To me its looks bad. Based on how it looks of the ones I took out in the pictures, anyone agree? Or I could have waited?

 

Their toast but they look to have done a good job.

 

30k miles being the recommended interval, overdue for certain.

 

They definitely look larger than .040 gap
The “look” looks good for the mileage.
It’s the gap/wear in this case.

 

It's done now. Oh well.

 

I got it from my brother with 85,000, drive it from Delaware to update NY in December 2022.
I didn't get a chance till today at 95K-ish.
I didn't think it would be this bad, but yeah, next change will be at 125K

 

Only 65000 miles late on those….

 

Those are the originals.

 

Wait those were the factory plugs? Definitely needed to be done regardless

 

yeah, half NGK, half Denso

 

The thread title should be “Glad I didn’t Wait Any Longer”

 

Wow I'm glad I read this post. I've got 65k miles on my plugs and I noticed at the last fill-up that the MPG seems to be slipping. I guess that will be my next project

 

So how easy or difficult were they to remove?

 

Wow. I’ve been thinking about replacing my plugs for a while. 54k miles on the original factory plugs and she’s still running fine. Sounds like I have another 40k miles before I really need to change them.

 

I thought it wasnt too bad, 1-10-difficulty was about a 5. Got new ones from toyota dealer for $2.76/piece.

 

looks to b burning clean.

 

It looks like the Densos held up a bit better than the NGKs.

 

~30k interval so looks like you did wait

 

It's crazy that they mix 3 Densos and 3 NGKs, that's why I like to do the maintenance myself.
My brother must have had a shop or a dealer do it and they know he's not going to check,
so they're just gonna say it is done and charge an arm and a leg for it.
It's sad that you can't trust a business to do what they're paid to do,
or the mechanic on the job was a lazy bastard, either way it's done.

And if I should need to take it somewhere,
I'll be watching like a hawk and checking everything before I leave. That's just me.

 

I'm pretty sure that's because spec from the factory is 3 Denso and 3 NGK,

which is why OP's truck, with the original plugs pulled out according to the post
are 3 Denso and 3 NGK

which either way is probably not going to matter; it's not a high-performance Ferrari extracting high power from every component, expecting every single part to be a certain way

those are likely the correct part numbers.
I have worked at shops and dealers. I don't see why anyone would do such a thing.
Either parts gives me the parts according to the catalog and I put them in,
or I order the parts through a distributor and put them in

a shop is going to want to put the correct parts, to prevent a comeback
they are still going to mark up the price and make money off you, regardless
