Thoughts on my Sparkplugs after 80k

I bought the 2019 in my signature from the OO a couple of weeks ago. I’m doing a complete fluid, filter and spark plug swap. I just pulled these six plugs and replaced them with the exact same plug. I believe the plugs to be original and they had 80K on them. It seems to idle a lot better. What are your thoughts on the Condition of the plugs? TIA

 

That’s about what mine looked like at around 80 too, and since replacing them mine is idling a lot better.

 

Money well spent. It’s a cheap enough change to have a fresh set of plugs in the vehicle. Waiting could not only effect engine operability but could also cause them to be tougher to remove.

 

I was a little concerned about all the white on the tips. Truck is running much better. The 100k recommendation by Toyota seems a little off. I think the recommended spark plug change at 60K by TW maintenance map is much more accurate. The truck idles nicely at 700 rpm now. With The old plugs the idle was erratic. The truck has a little bit of a shifting issue. It seems to be better since I put the plugs in. I am going to do a pan drop and then three drain and fill on the transmission. I’m hoping that helps the shifting issue even more.

 

What is the general consensus on checking the gap or re-gapping the replacement plugs you buy? Just take the factories word for it and trust what you bought is within spec or no? Last time I changed plugs was a while ago on a 2nd gen, and think they didn't come as advertised if I recall.

Back in the day I'd change the plugs, wires, distributor cap, and rotor on my 1992 Toyota Pickup Truck
once a year just to get out of the house. It was a piece of cake and the truck ran much better afterwards.

Not sure if I could even find the spark plugs on these newer vehicles today.

At 80k I wouldn't expect the plugs to be pristine by any stretch but those look reasonably ok for that mileage.

I'll probably have mine changed on my 2021 at 60k whether they need it or not, that is if I live long enough to do it.
Otherwise I'll have a letter in the glovebox for my son to get it done.... he's hoping for my early demise as it is, I best
write that letter now.
