spark plug change

I use Platinum +4s, no problems for about 10k kms so far. In fact, no problems at all.

no problems yet. I work in parts store and these are the junkiest plugs, they have the most come-backs of any other plug. Stick with OEM recommended iridium, it lasts so much longer than platinum and the smaller electrode you can find the more consistent the spark will be throughout the RPM band ensuring proper burn and even cylinder pressure cycles.

100% agree!
I was a Saturn Forum regular and we told everybody there that those plugs are sheet and made the Satty cars run real BAD......
Just trust Toyota's engineers and go Iridium or leave it alone.
