NGK Lazer Iridium Plugs is what I got to replace them in my car. I believe those are what Mazda OEM plugs are, but it’s just cheaper to buy the NGKs from a part store.
use NGK spark plugs, the best ones are the PFR6Q
Pick up some genuine Audi R8 Red-Top coils (not kidding, much lower failure rate) and some fresh NGK Iridium spark plugs.
I had this very same problem where on my 07 V6 the acceleration and power was off. I had replaced my spark plugs with NGK Iridium plugs and after dealing with the horrible performance I decided to change them out for OEM platinum (copper) plugs. This made a huge difference and could immediately tell a night and day difference. Regained the torque and power that was missing.
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.
Went with NGK spark plugs that was bundled with some generic wires and coils, not ideal but it’s all I could afford at the moment
Get rid of those ASAP. These are prone to breaking their ground straps. Myself and many many others have fell victim to this.
My brand new out-the-box WEN 3500 would barely start until I tossed the Torch and replaced it with an NGK. It now runs as designed. Too many others have had similar issues and that's why Torch is widely regarded as junk.
