Just got my 30k service, and I don't know why this seems like a rip to me, but it does.

My dealership said that I couldn't even upgrade to a better plug because they would mess with the computer and timing of the truck. Toyota only recomends the basic OEM spark plugs? Is this guy kidding me? I think my last vehicle went over 100k without changing the plugs, and it ran great.

Anybody have any thoughts on this. I would rather upgrade to a better/longer lasting plug than change them every 30k.

Really?!
is that all they last for?
I didnt' even realize that! Like you said, I assumed it was good for 100k or so...
hmmm... I am going to need to change plugs every year....

Exactly, and lets face it, that's all a dealership tune-up really is: replacing spark plugs. And what do they cost at autozone $4.00 ea?

I just don't know why you can't upgrade to a better plug.

Haha, true!
I was at the dealer today (roof ditch molding fell off... - warranty work), but generally, I don't have any work done by them.

Hmmm... so there ARE alternatives.
not a bad price for Denso Iridiums either.

The 4 cylinder has 100K mile plugs. The V6 gets the normal plugs that are recommended to be changed at 30K miles. Some find that at 30K, they really needed to be changed. I changed mine at 48K and they looked almost new. I'm not sure if I'll change them at 30K or go another 50K based on how good they looked before.

If you do a search, you'll find that many have swapped them out for the iridum or platinum plugs without a problem. You just won't see that info in the book at the dealership. Going aftermarket plugs can cause all sorts of problems and you'll find in past posts that's exactly what happens. So either stick with the OEM 30K plugs, or with Toyota's Iridiums or Platinums that others found do work in the V6 (by Toyota's plugs, I don't mean you have to purchase them from the dealership...the link above has them too).

It does seem funny that Toyota's top taco engine, one with sophisticated VVT, etc, still calls for old tech plugs. I know your dealer's claims about timing and computers is idiotic. I think I remember a couple years back some claims that the iridiums made their truck run poorly, but I haven't seen anything like that since.

The best explanation I've seen for short-life plugs in the taco 1GR-FE is that Toyota is worried for some reason that they will freeze into the aluminum head if you let them go too long. No data here at all, but it is at least more reasonable than your dealer's claim. Maybe the 1GR-FE has some unusual heat distributions that make it slightly more prone to this. Dunno. If you do go long-life, at least use anti-sieze.

It takes maybe an hour tops to change your own plugs, for me that's every 1.5 years or so. I usually spend over an hour a week cleaning my truck, so an hour every 1.5 years isn't a big deal.

just get some iridium plugs and call it a day. after doing a lot of research on here, i found that many ppl have done it (some ppl also against it). but its suppose to be good for 90-100k.

Totaly, spark plugs and brakes are a piece of cake, and will do this in the future. Just don't want to hurt anything in the process.

Just use the OEM plugs, use anitiseize and change them every 30 k miles like they say. The chances of having a plug seize in the head will be much less if you do this vs a long life plug that stays in the engine for 100k miles,
I put a ton of miles on my truck and I'm still going to change them with OEM plugs like they say, when I did them the first time the plugs were pretty worn and the gap was definately bigger than it should have been compared to new.
If you are saying 15k miles is your average per year do you really want to have plugs stay in the engine for nearly 7 years? Think of how many times the engine warms up and cools down in that time that plus 7 years... cant see why they would seize in:ugh3:

GC, I made the same mistake. I thought that the plugs were good for 100k, turns out that it is true on the 4 bangers but not the 6s. I had 60K plus on my first set, changed them with OEM Densos, <4$ each at the dealer. Don't be shocked when one bank are NGKs and the other are Densos, that's how Toyota does it. Get new Densos and forget about it.

BTW, the easiest vehicle that I ever changed plugs in.

When I replaced my plugs at 30K (around last Christmas) on my 07 V6 Taco DC, they still looked great. Very little wear on them. They looked almost new!!!
But, I'll just be changing them every year and half or so, so it's no big deal.
(Other than getting those drivers side plugs out!!!)
