Welcome to the forums.
There's no right or wrong intake. They are all different and have different styling and sound. Click here
Intake/Exhaust - Nissan 370Z Forum and scroll down the page (next few pages) You'll see them one after another.
I believe STILLEN G3 is the MOST popular intake on the forum. There are few members with Injen long tubes, HKS, JWT etc.
Good luck
