Replace plugs every 30k?

I have a 2011 DCSB TRD Prerunner. I heard that the plugs need to be replaced every 30k, is that correct? If so why, and how many of you have adheared to that recomendation.

This newbie says thanks!

 

Yes 30k for the V6. Do it yourself, the plugs are $3.25 from the dealer and it takes an hour to do.

 

^This. Although I'm at 47K with no change yet. Truck runs fine although I noticed the pickup is not as it was when new. Not changing the plugs at 30K will not do any damage will it?

 

I changed mine every 40k miles. They didn't seem too bad at 40k.

 

I changed the plugs at 30K and 60K as Toyota suggests. Why? Because the Tacoma uses copper plugs, not iridium. Both times the plugs were ready to be changed. They didn't look terrible when I removed them but the truck ran noticably better afterwards.

 

^ Yup!

I just got my plugs changed today and you can notice the difference.

 

I adhered to what toyota suggested and did them at 30k. Buddy at work has an 07 and didn't do it til 48k. We changed his plugs a few weeks ago and an engine noise he had went away. That should tell you something right there

 

i did mine at 35k..and then at 70k. no diff whatsoever. the plugs that came out both times looked damn good. gap was a tad wide, but other than that, everything looked good.

i actually had a tank of awful mpg after the first change. glad that was temporary!

 

For about $20 for a set of plugs, why WOULDN'T you adhere to Toyota's recommended service interval for spark plug replacement?

 

I did mine at 30 and 60 and they were fine but I will stick with the schedule. It doesn't really take that long and you don't have to remove much at all.

 

Driver's side is a pain in the butt on the 6 speed. They routed the clutch hard line right in the way and mounted it to the intake manifold brace that needs to be removed. It's bent around it in such a way it doesn't want to let go of it and wants to bend the line. Thanks to that it took me 15 minutes for the passenger side, 2 hours for the driver's side.

 

Changed mine the first time at 80k They looked good, truck had no change in performance. Ran great before and after... as usual

 

Whoa, did not know that the change interval was 30k. Guess what I'm doing this weekend.

 

But this begs the question.... why? What is the underlying reason that demands the 30k change?

 

I think Toyota is being over cautious. Other (less reputable?) manufacturers have 100k intervals. Like I said mine looked good after 80k. Maybe as our engines get older they will require more frequent changes.

 

I probably will change mine every 35k

 

i change them out every 30k...im at 119...so time for new ones again

 

After i changed my plugs last time, it was about 3 weeks ago now, I noticed a huge difference. I don't know who owned my truck before me but fuck sakes they are dumb, they even cross-threaded one of the plugs and it was a bitch to get out. After the new plugs my truck felt way better in the pedal and way more responsive.. it felt like i was running on 5 cylinders before compared to now

 

I'm not sure of the exact reason that Toyota does this but copper plugs are a better conductor of electricity than most anything else. I have to assume that the engineers at Toyota had a reason for using standard copper plugs as opposed to some more exotic metal therefore I will use what they call for. I changed them on my 2011 Prerunner at 31k and they were slightly worn. It took maybe an hour or so to change and that was taking my time. Changing plugs for me every 2 years or so is no big deal.
