Best Sparkplug for my HR

Best Sparkplug for my HR
Hey everyone,
I'm getting a re-tune on the 23rd of September, and I would like to replace my current plugs with something else. I did a little bit of researching, but I can't seem to find what the best spark plug is to use for my VQ35HR. It seems like the top choices are sticking with the OEM Denso Plugs, or switching over to these HKS one's. But then there's also the popular NGK plugs that everyone seems to swear by, so I'm kind of lost on which one to go with.
*** Also, what gap should I go with on the new plugs? Looks like 0.044" is the correct gap
Not sure if this really matters since I'm not boosted or running nitrous, but here are my current mods :
My goal is anything above 290+rwhp
TLDR; what plugs and gap should I go with for my upcoming Uprev re-tune?

- Motordyne Y-Pipe w/HFC Attachment
- Agency Power Single Exhaust
- UpRev

He made 300rwhp, which is ultimately my goal and what caught my attention in the first place. His words verbatim were "HKS Superfire -M. Best plugs I ever did. Every tuner has looked at me and said those never go bad. Worth it."
I'm all for the butt dyno/pseudo perfomance gains, but after seeing his numbers I just can't help but wonder..

OK- let's get this straight once and for all. Changing spark plugs from the OEM recommendation WILL NOT result in a large HP gain. You can lose HP, drivability and develop other electrical issues by switching, but unless you have built a race engine with special needs, stick with ND or NGK to avoid problems.

Hey travlee! I honestly can't say that I noticed any difference, the car is very strong at wot before/after plug change; I doubt that one would be able to tell a performance diff. better or worse just by driving your car, whatever make/style it is. However, any differences in oem or supposedly fancy plugs may show up on a dyno, etc.
It would be interesting to know what the racing teams use and what they have to say about their street cars and "if" quality plugs make any difference.
Myself, I just was tempted to snag the HKS superfire (one step colder due to FI) after talking to Coz at CZP. I had the local Nissan dealer change them out and with about 45K miles on my oem NGKs (HR long style iridium) they looked great (made for 100K miles), but I wanted to possibly get a more efficient spark if possible and maybe get some if any benefits; these plugs are good plugs and no way are going to under perform compared to oem NGK. He told me they were made by NGK; can't go wrong with them and I always went NGK in 3 bikes of mine in the past. Are these worth the extra $ (I think I paid $26 per!)? *still, the oem iridium NGKs are hard to beat
