Yes to all!
Just search the forum.
Apparently the stock induction is great and doesn't pose much of a restriction till everything else is upped.
In the meantime look up HKS or K&N etc reuseable panel filters available locally from the usual suspects, and the resorectomy or resonorectomy mod, the latter for more noise.
Both are DIY. Replacing the resonator with a DIY intake trumpet might be louder still...
From what I've read, aftermarket intakes are much louder even in a cold air box, so if that's what you're after, research those.
I put in a reusable panel filter... for just a tad more noise and the re-useability factor.
