My car is BPU++, it has a front mount intercooler, cam gears, and S-AFC, and dynoed at 400 RWHP. My car is idling pretty rough right now, will new plugs help that? What kind of plugs should I get with my current setup and what should I gap them at?? Thanks.

NGK 3330's at .31 gap should be good.

I tried both 3330's and 6097's. I liked the 6097's better. Mohd listed great reasons that the 6097's would be technically better. Personally, I just paid the $12 per set to see which I liked... doesn't take too long to switch them out!
