Anyone have feedback on NGK Ruthenium Plugs

[greenscales]

Driving a 05 V6 Sport - not extreme conditions, except occasional Baja desert and LA traffic. 200k on engine w/one rebuild (prior owner must not have maintained). Otherwise going w/NGK or Denso Iridiums when I change my Amsoil Signature.

The Rutheniums don't seem to be in wide distribution, but curious nonetheless. Thanks

Hmm... you've caught my attention! I will have to check these out.

I'll say it now though, you'll not see any improvement on a stock naturally aspirated engine. These 4Runner eat spark plugs due to having a waste spark system so it's best to stick with the recommended plugs in your owners manual or service manual.

Funny
I have a 2012 Genesis and it is time to the change plugs (a task within itself!!). These came up on RockAuto as SUPERIOR plugs. I think I will try them. Thank you for posting this as it reminded me it is time.

I did this spark plug exercise at one point... iridiu this, long life that, plus mounds of reading and overthinking spark plugs.

Ultimately I just defaulted back to the owners manual. I decided to keep it simple and just use what they recommend.

It might not be exciting, but it works, and I have the piece of mind of not trying to reinvent the wheel on my own.

I've been running NGK 92400 FR7BHX-S Ruthenium HX Plugs now for six weeks. I chose them at range 7 to accompany the installation of the TRD SC. Ordered from Summit late February based solely on NGK marketing - no user reviews available back then. It took seven weeks for them to ship.

Since they went in with the SC, I can't comment on their performance contribution (truck says Vroom) and it's too soon to tell how well they'll hold up.

It's getting time to do mine and I am thinking of these as well. NGK 96355 {#LFR5AHX} Ruthenium HX.
Any updates on user experience yet?
Thanks,

It's time for my spark plug replacement and I'm curious if these will be interesting to try, not looking for performance improvement, but I'm hoping to experiment, I'm thinking the only difference might be a 'crispier' ignition and hopefully longer lasting. Are you saying it's not worth it completely or it's not worth it if you're expecting performance level differences>

Late reply I know, but the rutheniums are single ground electrode plugs. Our engines are a waste spark system as we only have 3 coil packs but 6 spark plugs. That means that both plugs get fired twice on every sequence as there's 2 plugs on 1 coil. It causes the spark plugs to wear down very fast if you don't have a dual ground plug like the manual calls for.
