Hey NICO,
I was wondering if NGK V Power BKR5E-11spark plugs would be good to run in my N/A or should I just get NGK IX Iridium/Spark Plug BKR5EIX-11?

No, the only plugs to use are NGK pfr6g-11 fro NA or NGK pfr6b-11b for TT. They are not long enough for the engine as the ones I listed were specific for these engines. It also looks like the seconds ones you listed are about as much as the ones I listed, so why not get the right ones?

When I first got the car years ago, I bought the parts store type of plug, it ran fine till I either it reached higher rpms and WOT. The idle was ok, but soooo much better when I bought the correct ones.

Yupp, plenty of people will tell you the same story nissanfreak told. The VG30DE and DETT hate any other plugs but those listed. They're $55 a set (6) from Z1.
