Ruthenium spark plug (NGK)
I would only stick to OEM plugs or NGK part number FK20HBR11
These engines are sensitive to spark plugs. Original plugs are pricey but they last a long time. I would avoid buying ngk from online, because the majority of online ngk plugs are fake. Original ngk's cost around $11-12 make sure it is from a reputable scource

I doubt you will notice anything anyways, they're just spark plugs...

I wonder what is worse than the original. ⁇ Is the startup unstable or the acceleration not as good as it used to be? ⁇ I already bought it from Rock Auto, and I regret it.

@fey725 I've had them in my '11GS350AWD for about 10k miles. They work fine, but are no better than the original plugs. Just use DENSO or NGK and you will be fine.

@fey725 The NGK Ruthenium plugs will work good. I have used them for awhile and have not had any problems. It is recommended to use the original DENSO plugs or NGK because they are known to work correctly with our cars.

They are not worse than OEM, its just a different type of plug. Its really only recommended for modified vehicles, a stock 350 doesn't need them and won't notice any changes.
