Replacing spark plugs

Just a quick question, what brand of sparkplugs is everyone using these days? Toyota's or aftermarket. Thanks

Toyota brand replacement. Chris should be chiming in shortly. I'll shoot you the link.

General consensus on this forum is to use the factory Denso copper plugs in the V6. Iridiums in the I4.

 

Thanks for the great pic's and info. I was curious as to why Toyota wants the plugs out every 30K? It doesn't seem to make sense considering most plugs last a very long time.
I had it figured it was a way of making $$ for the dealer. What do your plugs look like when you change them out? Is the gap significantly increased?
Thanks again, Jag for the close up photo's , will make it easier in the spring.

That was all thanks to Chris. Don't want to take the credit away from his great work!

 

Thank you Chris.
