Newby looking for power mods for '10 370Z

Nesbit

I am new to 370s (all Nissans for that matter) but not new to tuning / mod.ing engines on my own.

I am looking optimally for not-terribly-invasive engine mod.s. I.e. air intakes & software. Would like to keep all relatively reversable for warranty reasons.

What's best / hot out there for '10 370?

I know this is an oversimplified and basic question so thanks for help. If someone asked me this about a Porsche or Mercedes I'd be thinking "boy what a newbie, where should I begin?".... so again thanks and if need any clarifying questions asked or narrowing down please let me know.
