What kind of air intake systems for '99 4 banger

Hello,
What kind of air intake systems for a 1999 V4 2.7L tacoma are there that could give me a lil more power, gas mileage, sportier sound? I'd prefer to keep it below $200 if possible.

Would something like this be good?

Or how about one of these

deckplate mod would yield the most gains per cash spent id try that first and if you arent satisfied take the plunge on something nicer. although i have heard that it helps out I4's alot more than v6's i noticed some gains on my v6
