There was a thread on this just a few weeks ago! Can't remember if it was here or on FA, but the thread had a link to a Japanese performance mag that tested all of the major intakes. They tested Apex'i, HKS, Blitz, and K&N for flow and filtering effectiveness.
They all flowed very, very close (within 3 hp) on a ~350 hp car (Supra, iirc). I can't remember, but either HKS or Blitz was the worst on flow.
What I do remember is that Apexi was the best. K&N was close, but Apexi ruled on both filtering and flow.
And it's ~$100 on ebay.
[EDIT] so yeah, ditto to what IvoryJ30 was saying. Only I can't remember ever seeing a K&N that included a venturi-shaped adapter. The filters are like $45 tho, if you can find an adapter.
