How long will Iridium Plugs Last?

[ricamryman]

I bought some NGK Iridium Plugs for my 93 LE, 3VZFE V6 Camry, how long will these plugs last? Can I go 100K miles?......

Which kind of Iridium? IIRC, the 3VZ uses a distributor waste spark system and benefits from the use of a certain type of spark plug.

NGK Iridium Plug # BCPR6EIX-11, according to NGK's site this is the proper plug for the 1993 3VZFE....

Factory Iridium Plugs are good for 120K

Sounds like after I install these, they could quite possibly be the last set of plugs I will ever need?......Since I am at 134K miles......Nice!....

NGK Iridium-IX in waste spark system?? I wouldn't trust them after 30k miles, just IMHO ...

Denso Double Platinum or NGK Laser Platinum 60-90k miles should be OK...

I highly doubt NGK would make them & specify them for my particular application, if they would not last a while?........

well, they are also SPECIFIED for gen4 camry, solaras and so on, only difference vs OEM factory design (double ground electrode) is the Iridium-IX have a single ground, so they last up to roughly half the time double ground OEM plugs in a waste spark system ...

Looks like those are the Iridium IX plugs. They'll work perfectly fine, but i'm pretty sure you're supposed to stick with Laser Platinums. edit: Yep, posts above confirm that.

I guess the only way I will find out is when I install them and drive for 30K miles, then report back here on how the car is running!.....

by all means, use them if you have them already, they are VERY decent plugs

just don't expect them to last as long as OEM would.

How long do the OEM plugs last? I had the Toyota Dealer replace my current ones around 30K miles ago?.......

they should be good for 60k or up to 90k miles with no problems. I would keep the OEM ones in there for at least another 30k miles.

just check what shape they are in, color and so on.

There is a sticker that even says not to use single electrode plugs on the 1mz, pretty sure its the same for the 3vz too.

According to what Lynch posted you need, NGK Laser Platinum BCPR6EP-11 or Toyota Denso Plugs. Doing the rear bank plugs is not much fun as it is. I wouldn't want to replace them again in another 30k miles.

I assume they used Toyota Denso Double Platinum, so it should last for another 90k miles if I'm not mistaken. Service Interval says to replace Double Platinum plugs every 120k.
