That's true, temps play a big part.

I believe it's something to do with the way the ECU handles fuelling and ignition. Playing with hondata, I realized that even with the stock ECU, the fueling and ignition is compensated depending on IAT as well, which is why cold intakes seems to give better performance.

But if you noticed track cars from various j-manufacturers, they actually run open pods, so I think by reducing compensation on the ECU based on IAT, open pods can achieve the performance as well.

For mine, stock airbox gave me worst performance, but we all know that depending on situation, the mileage may vary. So testing is the best way.

I like AEM's intake, but worries of hydrolock abounds if its used as a daily driver... too many rainwater filled potholes in Malaysia. if 50cc or so of water gets into the engine.. bye bye engine.. (O_o)
