I've run the NGK ruthenium in my sierra with the 6.2 and they ran great but I notice they aren't the right gap.
You use a **NGK BR2LM.**
I’ve been running NGK Ruthenium for a year now with 0 problems. Supposedly they last longer and are more stable with less dispersion according to NGK. Going to stick with them instead of Iridium or Platinum.
I have ngk spark plugs and I went with z1 high ignition coils
if you don't want to pay for VW boxes, NGK ruethiums are a killer deal on rock auto, I've run 2 sets through out alltrack without a hiccup, about 60K total.
I couldn’t use any other spark plugs I had to use those or my car would run like crap.
In my 2012 with the 2.5L engine, I replaced my spark plugs with Bosch Iridium (#96302), around 90K miles. It's been great since.
Lol 560 for 4 piece spark plug? That plug better be made of gold even laser iridium also doesn't cost that high. Good ngk iridium cost no more or less than 300. That syn 3k for 300 can get a far better brand n enhanced thermal and oxidative stability grade.
I put the expensive double spark, spark plugs into a Mitsubishi galant one time. Plugs were supposed to be hotter and make the car run better, after a couple weeks I swapped them back out for nkg’s that I checked the gap on, car ran better.
Never use bosch plugs. I work in a bosch car service and we won't use em, NGK only. Bosch stuff is garbage
