Cobra or Trick Flow intake with GT40P heads?

[Josh91]

Either intake will work just fine. The TFS intake has more HP capability, but the Cobra isn't maxed out until around 400 or so. The 19#'ers will be fine as long as you have enough pump (255) and an AFPR. I got my Cobra because I found it used and it was a good deal. $300 for intake and FMS 65mm TB. They can be found used for great prices. The other good thing about the Cobra is that it has a built in EGR spacer, so that is money saved over the TFS intake.
