IMO, all you get with most CAI installs is a bit of noise that some misinterpect as increased performance and a "WOW" factor when you open the hood.

Like RedRide stated before, its seems purely a WOW factor.
Then I got a gain of 15 whp from a pulley, header and axle-back exhaust. Went from 92 to 108 whp.

You're saying the intake contributed nothing to that change in numbers, as measured on the same dyno, with reasonably close ambient temp and humidity? c'mon guys.

This argument just won't die. A well designed intake that lowers intake temps and increases flow makes some power; maybe not a lot -- but some.

And mods add to each other's increases -- I believe ilikerice has agreed to this in other threads. (but maybe it's my wishful thinking)

100% agree on this statement.. I have said that before. This mod is beneficial when put together with other bolt on power adders like headers.. I was just stating CAI alone I found is not enough. More air in means more air out.. time to upgrade that exhaust manifold.

I still kept the CAI in means to one day buy an exhaust header and mid pipe from you garm.. BUT.. I really want that turbo also.. lol.. I am torn

Exactly! Even if it is slightly more free flowing + colder air it is going to increase performance over stock. Even if it is only a few hp, in our tiny engines a few hp goes a long way.

And although the afe is not a legit CAI it does still help with responsiveness and midrange power.

If that is true, there should be a spectacular difference in performace between suimmr and winter temps.

Yes, there is some slight difference between drivng in 90 degree temps vs sub freezing temps. However, the diffence in intake temps (stock vs CAI) is insignificant as far as this is concerned.
"A few HP gain" just because you lowered the intake temps a few degrees? I don't think so.

Like I said.... when a car is moving all intakes are fed cooler air!
When a car is not moving, which intake do you think would be fed the coolest air..... A short ram the has its intake next to/ on top of the engine or, a stock air box that his its intake right bebind the grill?

There is absolutely a difference between cold days and warm. I can definately notice a difference.

And a CAI would move the coldest air into the intake manifold at a stop.
