Does the 06 V-6 use the 30,000 mile spark plug?

Is the 30,000 mile service spark plug still specified for the 06 V-6? I would appreciate if someone could check their 06 manual.

Thanks.

It should as it is the same engine (1GRFE) in the 2003-2005 models. No major engine changes were published so it should be 30K for spark plug change.

Yes, the 06 V6 does have 30K-mile plugs.
The V8 went to iridium 120K-mile plugs.

Thanks.

I realize that the powertrain hardware is unchanged but there is a remote possibility (because of expense) that Toyota recertified the engine emissions due to some other reason such as calibration, and also elected to change plugs also.
