Denso Platinum TT Plugs - thoughts?

After some research, I settled on Denso Platinum TT plugs for my '05 SR5 @ 178k miles. Coils aren't giving any problems so they will not be changed.
Dealership and other resources say gap is .043.
Yeas or nays on these plugs?

 

I have Denso Iridium TT for my 08 v6. Never a problem.

 

Thanks.
I thought iridium plugs were not recommended for 4Runner V6's, especially in the '04-'10 year range.

 

Is Toyota still installing Denso on 1 side & NGK on the other?? They were doing that on my 08, 12 FJ. I R&R @ the OEM recommended mileage, didn't on 15 Tacoma was a waste of $$$.

 

I have never heard of anyone, much less a dealership, using two different brands of plugs on the same engine!

 

you bought that used eh?

 

Well, not taking the time to look through my maintenance notes on my truck was a dumb mistake.
The plugs do need to be replaced, however, they are iridium, not platinum. So I have to waste time returning the platinums to get iridium. Thank you Amazon for making the return and reorder easy, though!

 

iridium and gap not adjustable

 

Do you mean the gap on iridium plugs is not adjustable? I guess the iridium plugs for an '05 V6 come pre-gapped at .044.

 

That was fact. I didn't believe it too until I saw it!!!

 

Nope I haven't bought a used vehicle since 1993 Because I do NOT trust people.

 

This wasn't from dealership BUT from Factory. I bought it NEW! Installed NGK in all 6 cylinders then.

 

Mine came from the factory like that. Two different brands. Many people have reported this over the years.

"The reason for this, as explained to me by the Toyota parts guy, is that due to some import agreements, there has to be a certain percentage of parts from each of several manufacturers in the vehicle. He said there wasn't any technical explanation for the difference. As a matter of fact, Stevenson Toyota doesn't even carry both types anymore because it's not necessary."

Not sure where you heard that. As I mentioned already, never had a problem with the irridium plugs. 160,000 miles on vehicle and three sets of irridium.
