I have never heard of NGK plugs giving anybody on any platform any trouble unless the bought the wrong heat range plug or did not gap them correctly. I have a set of NGKs i am actually getting ready to put in lol.

OP, I had a similar inquiry when I changed mine out. I've ran NGKs in my past three cars and never had an issue. After some reading on here, a lot of owners would throw codes, misfires and a laundry list of other issues.

I installed the Denso plugs 20k+ miles ago and have not had a single issue. Unless you're running a boosted application and require colder plugs, the OEM plugs are the way to go.

I would assume it was the gap that caused that, i actually tend to make the gap a tad smaller on every car i have owned then OE, so in this case instead of a .44 i will have it at like .4-.38 around that range to get a more "robust" spark, it has worked well in my previous cars which includes quite a few VQ powered nissans i wasn't planning on changing that with the G37.

I always check the gaps - even for pre-gapped plugs. The Denso plugs were all at OEM spec so I installed and have not had an issue. No clue why the NGKs cause heartaches; even when gapped properly.
