Iridium spark plugs
Time for 60K miles maintenance service. 2 big item. One is flushing braking fluid(I can do it in Toyota for USD100.00). The other is replacing Iridium spark plugs for USD330.00.
start and acceleration of my 2011 LS460 are still good. Is it worth to replace the 8 iridium spark plugs? Will it make my driving even better?

Here's my DIY I posted a couple of years ago....:

If you have any questions let me know. As for the brake fluid......did you check other dealers? I only pay 79 bucks at my Toyota dealer, and that's in Canada which is usually more expensive than the US.

Make sure you source some good plugs: See your owners manual or http://densoautoparts.com/find-my-pa...icle-selection
I went with the Denso TT plug because it's the latest technology. You can change your plugs 3 time for what the dealer charges smh. The hardest part is putting those engine room covers back in. Make sure you have a long needle nose pliers; preferably with a bend, to easily extract the coil seals from the valve covers. If it takes you 2 hours it's because you ate lunch while you did it.

You're welcome. And no matter what anyone else tells you...DO NOT use anything but Denso plugs. Not sure if I mentioned that in the DIY or not. Here's the best deal I could find, which is about 80 bucks for all 8 (2 pkgs of 4 @ $40 per pack), and free shipping. http://www.ebay.com/itm/4-X-DENSO-IR...1WAtle&vxp=mtr
