Thanks for all the helpful replies to previous questions. I really appreciate the knowledge base that the regular users here represent.

I called a couple of mechanics for a quote on the 30K service for my 2008 Tacoma. Both were in the $400 ballpark, but one remarked that it was probably a waste of money to put expensive double-platinum plugs into the vehicle if they will be changed every 30K miles per the maintenance schedule.

I really have no experience. So is he correct? Do I need Denso double-platinum plugs that the mechanic sells me for $18/plug? Or can I just get standard plugs and go with those?

Thanks in advance

from the factory for some reason one bank is copper and other is the good ones!

i would still do the good ones
