Spark plug NGK or Autolite

I’ve run NGK platinum and Denso and they both work well.

Anyway, I finally made the effort and took the plunge, choosing the offline method of sourcing the NGK. That aside, the first pull on the throttle, I felt the difference. It was, for lack of a better word, 'softer', an easier pull. The change showed up in various other ways. A smoother ride, easier acceleration, an hour or so later, easier gear shifts and the ability to be in lower RPMs and speeds in higher gears.

The car started to misfire at boost so I swapped plugs to NGK PFR6H-10 and everything is good now.

Don't use Bosch sparksticks.

I use iridium’s NGK haven’t had any issues.

Just replaced my previously purchased NGK Iridium from Rockauto.com After 100k miles the looked like I put them in yesterday.

NGK Laser Iridium is the Honda spec and what I buy and have had no issues for 5x 105k intervals.

I read that NGK plugs already have a coating on them, so I didn't apply any when I fitted new NGK BKR6EQUP plugs. Torqued them to 25Nm.

The old ones (also NGK) came out easily and I used a bit of tubing to hold the plug as I installed it into the thread, making sure it was threaded on straight before switching to a ratchet and torque wrench to screw down and tighten.

I used NGK laser iridium to replace my probably original 256k mile acdelco plugs. Noticed exactly no difference in performance.

That auto lite is no goood

There is 0 performance or ignition upgrade to the ruthenium compared to motorcraft OEM ones. I tested the 2 back and forth for several weeks and saw no noticeable improvement in either. The car ran the exact same. Rutheniums run like $50 ish a set, motorcraft I can find for around $25 a set, no brainer, motorcraft. I am also stock. Don’t buy into the hype like I did.
