I decided to give the NGK Rutheniums a try earlier this year after reading about them on this thread I've been happy with them so far, the engine ran noticeably smoother than with the old plugs (but that could have also been simply due to new plugs).
Owner reviews for spark plug
I replaced mine last week and used anti-seize lightly. No problems that I see.
if you want to save a bit and still want some quality get bosch plugs those are good too, I’ve used them before and they were pretty good as well.
Replace the plugs with NGK or Denso.
Denso iridium plugs, no more no less and no exceptions.
I have the OEM RS7 plugs in my car for 40,000km ever since going to stage two with zero issues and will buy them again.
denso iridium. do them and they’ll be good for another 200k km or more
Brisk silver er10s if you need 2 steps colder. I had the ngk plugs, but they wore down just as fast and are more expensive. Brisk silver are like 10 bucks
