"You have two choices for plenums - Crawford or Kinetix. Crawford is gorgeous, but requires you to send them your plenum as a core and requires a strut bar to be purchased from them. Kinetix is not as good looking, but can be changed back to the stock plenum because you get to keep yours. Plus you can maintain the factory strut bar and paint it if you're getting really motivated.

JWT Popcharger is the only intake I've seen with real performance gains."

I am going with kenetix Plenum mostly because you can keep your stock core, and you can put the enginecover back on. I personally think it looks like crap without it on there. But other then that, the new V5 Crawford plenum is niiice looking.

I went with the JWT because I was affraid of LOSING HP with any other intake. To many stories of people taking off their intakes and either switching with stock, or to a JWT pop charger and being able to notice a positive increase in power.

Just to clarify, I didn't mean anything bad about Nismo parts, it's just that there are other manufacturers making similar or more gains for less money. I bought the Borla because of the sound. Performance was a distant 2nd place, because I knew I was going FI anyways.

Just to clarify, I never thought you were saying anything bad about Nismo

Everyone has their own preferance with exhaust, And that's all that matters. You can't really have people saying get this or get that. You need to listen to sound clips, and looks at pics at the very minimum. I personally got to see them in person, from there the Nismo is what appealed to me while other systems appeal to others.

So go check out which one you like the best, and go for it!
