Early Spark Plug Replacement SC430 - 30K

I am taking my SC430 into the dealer for the 30k service. I am considering replacing my plugs early (they are not due until 90K). I have a 2000 LX470 and I just changed them a 90k and -- WOW -- what a difference.

Has anyone changed the plugs on their SC430 early?

Any performance change?

Mine bogs a little off the line unless in is in ECT/PWR mode.

i have tried all of the top plugs out there. My only recommendation are the NGK Iridiums.

Bosch plugs do not do well with Toyoto ignition systems. this from two Bosch reps and my personal experience with customers.

Nippos are good but tend to wear faster vs the comparable NGK plugs in my own testing.

I change my plugs every 25k miles. 90k is a bit too much.
