wonder if higher octane fueled used would show a higher result in HP. Either way i would not change unless it was needed.

 

I saw an ad for these spark plugs
http://www.pulstarpulseplugs.com/ (though they dont make plugs for the G yet)

And it made me wonder - do you guys know if upgrading spark plugs will be a worthy NA mod for the G? Perhaps prev gen G35 owners may know from experience. I have heard some cars benefit more than others and that some cars report 3-5 peak WHP, increased fuel efficiency, and improved throttle response....I am planning on doing N/A mods only (eg Intake + exhaust + ECU reflash/tune) and was wondering if upgrading spark plugs is a worthy addition to that basic set of mods.

What is the truth behind upgrading spark plugs and how may it benefit or apply to our 08 G37s??

Thanks!!!!

PS
Does anyone know if our spark plugs are identical to prev gen G35 coupes? I found some NGKs that are nice but they don't have anything for 2008
