Default Intake System Question

I have reviewed most of the conversations that have taken place concerning the aftermarket "cold air intake system". The question that I have though is, do they really provide the performance enhancements as advertised over the standard box setup with a K&N style filter? Or is a placebo affect of the sound making one think that there is better performance?

It seems that the possible volume of air intake is equivalent between the two systems. I could be mistaken but...

I am performing further investigation and analysis on this, so any help would be appreciated before a purchase like this is made.

Usually, and I mean absolutely most of the time - cold air inductions change the tuning at low engine speeds. That is to say, no real power gains (unless the stock setup is overly restrictive). On turbos, especially PT and SRT turbos - there is really nothing.

I found the intake gave me a boost on take-off, eliminated a lag between giving gas and getting froward motion. I do not believe the HP claims, but there is some gain. The stock setup is designed for noise reduction, not performance.

Here's a nice write-up from one of the other forums on air intake systems. Give it a read.

Ian - would all these be gone with an after-market intake? (Where are the 3?)

Thanks to everyone for their input. 3Bar, thanks for your input. You again provide some good solid information that is more than "it just makes it sound good." I now need to perform some analysis (the engineer in me) to really see if there is value in spending the bucks. It sounds like there may not be value. I will have to make up my own mind up on that one.

BTW, IRPT, I reverse designed from the original rubber molded piece. Then made on a rapid prototype machine. Can customize the top surface to add any graphic that I can import into my CAD system. Material is ABS which can be finished in almost any manner. Will do that next!
