my 04 RX330 has 113k miles and I took a peak at one of the front plugs last week. Those babies show signs of work. That iridium tip is tiny, very different from plugs I've seen in the past.
Ditto others comments, to ensure you use Iridium. My research has shown your OEM could be Denso or NGK. My local Toyota has the Denso's in stock. Local Toyota charges $250 to replace, Lexus about the same. I plan to hunt for a local Toyota coupon for a $150 for the next few months as I approach 120k mi.
Changing yourself looks like a lot of VERY COMPLEX work, where some bad stuff could go wrong. My .02 too!
Kudos to the fella who did it himself!

Use DENSO Iridium Power Plugs
DENSO is OE on Lexus. Get the Iridium Power plugs, they will give you additional horsepower and improved gas mileage. I put them in mine and could tell the difference in acceleration right away.

Well, Halfway through a plug change and have started off by attempting to remove the intake... Not sure if this was the right route... broke everything I could see free but the intake will not lift off the studs. Decided to take a break until tomorrow. Will undoubtedly have to rethink things when I am not tired. Will also look closer at taking the cowling apart to see if I can fit my hands down through there. Hope I am not bitting off more than I can chew here...

Ok, took the wiper cowl completely off, broke everything apart on the intake and still could not get it to free up. There must be something attached to the intake from the rear that I can't see. There is no way I was going to start fishing extensions and universals down between the fire wall and the intake. I figure I will bite the bullet a have my local Toyo dealer finish the Job... Erg, I hate when I can't finish something... They quoted me about $225 Labor for the rear three plug replacements. After experiencing the PITA that this job is, it is money well spent!

What I was told was that they had to up the Labor because the job is such a PITA... Guess I should have had it done earlier... If it was truely $189... Then they would have had me doing cartwheels and I would have taken the Plugs I bought straight back to the parts store... I think that $189 was the labor... The Plugs are $10 a piece and the intake gasket is $20. $109 is only an hours worth of Labor and that is impossible with this Job.

I went with the NGK replacements - three of them seem to be doing real well... Even with just half of them currently replaced, my idle has been smoother. Guess I was really due after 120K.
