got my replacement from Courtesy Nissan and installed them tonight.
All 8 of them had the exact same gap 0.037 ish which is about the gap that was on the oem ones I removed with 120K on them.
The counterfeits I pulled had various gaps: 3 were 0.020, 3 were 0.025 and 2 were 0.030 ish. I also noticed the lower electrode had a wider base on the counterfeits as well as a different font on the side.
SUV seems to idle better at about 750 rpm vs 500 rpm with counterfeits. I was getting lots of misfires at 500 rpm.
I haven't felt misfires at idle so far in my test drive tonight. time will tell.
