    My taco just hit 56k miles and according to Toyota service schedules I should have an oil change and spark plugs done soon. How necessary is it that I have the spark plugs changed? Is it something that can wait?

    Matt,
    I was also seeing that it recommends it at 30k. To me that seems nuts. I would go ahead and change them at 56k.. Pull one out and check it out. You can buy a spark plug gauge and check it/them

    I changed mine at 38,000. Not suren if they were ever done, and the truck does seem to run a bit better.

    TOTALLY worth the change- It'll be about 30 bucks for plugs from the dealer and the engine will like it. I did mine in the Tacoma at about 34K and just changed the wifes in her new 4Runner and the engines both responded REALLY well.

    I changed mine just before 40k miles, the driver's side ones looked worse than the passenger ones (and apparently that's a common find). As a result it idles a little bit smoother but no other changes that I could tell. If you haven't had them changed yet, you should get it done at 60k.

    None yet! It's new!
    My '09 calls for a change at 30,000. I just pulled them out, at 30,600 miles. By appearances, I'm glad I pulled them out - the gap had increased a good .002" to around .045".

    Just put in laser platinums or iridiums and they'll last longer next time. I put in a set of new NGKs and the truck is noticeably smoother, with better throttle response, at least initially.

    Side note: my truck exhibited the same weirdness as everyone else's: NGKs on one bank and Densos on the other. :)

    Don't waste your money on platinums or iridiums, just replace them with NGK's or Denso's (I can't remember which one the dealership gave me).
