I was under the impression those NGK's were the best plugs for the 1UZ, at least that's what I gathered on here when I bought them. My RPM's have dropped back down to when I seafoamed the other day. All is good, runs perfect, ultra quiet. I was actually driving and pulled up to a red light, and I thought my car stalled, but it's just running so smooth I couldn't tell it was on...

Really nice write-up, and with pics!
However, I seafoamed my SC400 a couple years ago and definitely didn't see any differences Car had 180k when I did that.
Also, Interstate batteries are awesome, one of the best out there!
And i think the only SC's that iridium plugs are recommended is ones with the VVT-i motor. You will see no benefit to using them in a 92-97 car, except you will pay more money for plugs.
