Usually, the SRT intake comes out on top with most people, even though it is more expensive. It's actually about $500 if you get from Steve at Carson Toyota. You will experience the most power gains with it as well.
well the best intake is the SRT becuase it comes w/ a ecu while the others dont. you really cant compare to the srt to the others unless you get them w/ a AFC, etc. and if you do get them w/ the afc then it would be better benefit if you add other mods like exhuast, headers, race pipe, etc.
if you get the other regular intakes w/o a ecu the cel will come on
if you get the srt the cel wont come one becuase of the ecu
if you get the other regular intakes w/ a ecu (S-AFC, AFR, etc) the cel
wont come on

I know the Rod Millen intake keeps the MAF sensor in the stock position, or as close to it as possible, so that's an option, but a lot of people either like it or hate it. It's a little more expensive than a comparable AEM.
If you get a header/midpipe/exhaust combo, go with an Injen + AFC and you'll really bump up your power a lot.
Another option, is the PLP Silent Flow intake. I used that right now. Doesn't look all Honda Hardass like an AEM or Injen or SRT might, but it yields about the best power increase on a stand alone intake without an ECU or AFC... and they're quiet and sharp looking. +9whp according to PLP. You can get them used on here for around $150, or new from the .NET store for $217. I don't think there is anyone that has used a PLP SFI and been disappointed with it.
