Spark plug pics 2GR-FSE Lexus

[1lieutenant]

Sorry for the second post on the same topic, but I couldn't figure out how to edit the first one.

Here are the promised pictures of the spark plugs taken out of my 2015 Lexus GS 350 at 60K miles.
These were replaced as required to maintain the emissions warranty. Let me know your thoughts.

Look just fine to me!

I would've been tempted to put them back in...

LOL. Agreed, but after the time spent to get access and the fact I already purchased them, they were going in! Seriously, they needed to be replaced to maintain the factory emissions warranty.

Look great. Do all the Lexus cars use multi-side electrode design?

Agreed, these were replaced with Denso plugs from a Lexus dealership.

Look at last pic bottom right. That plug bottom ground electrode looks totally missing, So not a wasted excersise. Of course it could be a picture focus thing too. Rest of plugs look like they have another 50k life in them

It’s the photo. All electrodes present.

It is always better to change them early that late.

The story those plugs are telling me is the engine is fine and you have nothing to worry about.

Toyota uses these for their D4-S engines(2GR-FSE/FKS/FXS, 2UR-FSE/GSE/FXE, 8AR-FTS, A25A-FKS, M20A-FKS, V35A-FTS). The theory is that if the center electrode gets carbon fouled due to DI, the side ground straps provide an alternate ground path to “clean” the plug.

I just replaced these on my friends 2018 Sienna that has the same 2GR-FSE engine at 115k miles and they looked like they can go another 30k with no issues.

Agree. That is a very happy v6.
