Default NGK Laser Platinum Spark Plug for T4R V6

Has anyone installed NGK PLFR6A-11 Laser Platinum Spark Plug on a 4th Gen T4R?

I have a 2007 T4R SR5 V6 4.0 Liter 4WD. It is time to change the factory standard spark plugs. I want to use platinum plugs preferably the Bosch 4 Prong plugs. But looks like those plugs are not applicable to Toyoto 4Runners.

The next best one is the NGK PLFR6A-11 Laser Platinum Spark Plug. The best price I have found so far is in Amazon at $11.89 a piece.

Would like to make sure if the part number is correct or not and if anyone has installed it? If so, does it work without any issues? Is this a reasonable price?

Thanks.

I believe the owner's manual specifies iridium plugs only.

I thought the V6 OEM plugs weren't iridium, just the V8 came with iridium. Or did it change recently?

I do believe you can now get iridium plugs fro the v6 now. SO only need to change them every 120k miles.

Good question. I think that they're iridium, but PM Brett (damaged110) to be sure.
And if so, Iridium is far superior to platinum.

I can't remember which one I got - Advanced Auto has good prices on NGK. I think I got the V-Power - it's the OEM version.

I wonder how much difference there really is?

Here's a list of what NGK has for the V-6 - the link would not work.

2004 TOYOTA 4RUNNER 4.0 V6 1GR-FE FI

V-Power LFR6C-11 # 5788
Laser Platinum PLFR6A-11 * 7654
OE Laser Iridium ILFR6T11 ^ 4904
Iridium IX LFR6AIX-11 6619

* “Laser Series” Platinum center electrode, and Platinum pad ground electrode
# Original Equipment Manufacturer, and/or Original Equipment Service Part
^ “Laser Series” Iridium center electrode, and Platinum pad ground electrode

IIRC the only advantage iridium plugs have over standard or platinum plugs is the iridium coating on the electrodes. It's much harder and therefore more wear resistant to the combustion cycle. That's why the recommended replacement interval is like 90k to 120k miles. I don't think they produce a better (bigger, fatter) spark, just last longer which is great in some of todays tight engine compartments where changing plugs becomes a 5 hr job.
Sorry a little off topic.

Thanks for all the suggestions.

Although Platinum plugs may not be recommended in the user manual, the NGK site below lists the NGK Platinum PLFR6A-11, Stock#7654 as applicable to the SR5 4.0 V6 1GRFE engine, also suggested by TNcaveman. I would prefer to have a better spark as suggested by 4Mudder.

If I go with the platinum plugs, will there be any negative impact? My 36,000 warranty is over, so probably it does not matter if Toyota stealerships have any issue with it or not.

My bad. The "iridium only" warning in the owner's manual applies only to the V-8.
