So I am looking to replace the stock intake on my BRZ and I have been researching/looking through forums about the intakes out there currently. But I cannot seemed to get a clear answer on which intake is the best.
First dilemma is deciding whether to get a CAI or short ram. I have read CAI is better but also short ram could be better with a heat shield or some sort of housing (forgot what it was called

). But it seems only Perrin has made a true CAI and other brands are short ram.
Which brings me to my second dilemma and the reason for writing this.
Which intake offers the best result? I know intake itself does not result in great power gains but out of the little gain it does produce, which one yields the best. From what I have seen/read so far, it seems Injen has the best results but then it seems AEM and Takeda also do too. I am not limiting myself on these so if you provide a better intake with proven results (i.e. dynos) it will be considered.

Finally, to add some notes. I care more about gains than looks. Also, I am not planning to get my ECU tuned until I get an intake AND an exhaust. So even if I decide on an intake now, I will be driving with the stock ECU for a while.
Thanks for reading this long post
