Let me put it simply:

Man logs intake temps before cold air intake
Man logs intake temps after cold air intake
Temps on intake do not change between the two

Man has intercooler, therefore, it stands to reason that the intercooler is efficient enough to get the intake temps down to a certain level (ambient) whether they come in 20* higher or not.

If, no intercooler, then sure the intake temps would change. That is not part of this argument though. Perhaps you should read the entire thread.

Lastly, if intake temp with one thing is the same as another, then everything after that would be the same. Air is not denser. Provided the same AFR, combustion temps would be the same. As well as EGT's.

My point was, why do cold air if you have an intercooler. I doubted that the temps would be very different at all if you have a decent intercooler. (By the way, for those of you who may have missed it, the intercooler cools the incoming air charge.) So if your intercooler is efficient enough to get intake temps down to a certain value regardless of the temperature coming into it, then who cares? Besides that, the extra run of undersized piping can not cause any good to come of the turbo efficiency.
One of the guys logged his intake temps, and they were the same before and after. Enough said. That to me, renders the gain from a cold air intake useless. If intake temps are the same without it, then who needs it.

It is the temperature at the manifold that will determine the density of the charge going into your cylinders, not what comes into the turbo.

You guys should quit hanging out with these rediculous honda owners so that you can stop convencing yourselves that some fairy sprinkles magic dust in your car that makes it go faster when you have a cold air intake on an intercooled application.
