Actually 03GTPLE is correct.
I did the fender well intake on my (now dead and gone) 2000 GTP. All that putting it in the fender did for a supercharged engine was cause the filter to get dirty REALLY fast. It has been a topic of discussion quite a bit actually, and after cleaning the filter a lot, I did some research on it and for a supercharged engine, it really doesn't make any noticeable difference because like mentioned before, the supercharger warms the air up so much that it most certainly is quite warm (hot) by the time it is shoved down the throat of the engine so to speak. I took the same filter and the same massive intake pipe, cut it short and was getting the same performance. Sure, maybe with some testing equipment the FWI may give an 1/8 HP of improved performance, but that is about it. It certainly felt the exact same, and then I didn't have to clean the darn filter so stinking much.
Now, a naturally aspirated engine is a different story. Any drops in the temp of the incoming air and you should see/feel an improvement.
Do a little research yourself and you will see what we are talking about and be better educated the next time the topic comes up.
Someone did a more scientific test back in 2010 and determined that the "HAI" was actually better than a regular CAI (Thrasher). A good number of highly respected people in the Grand Prix mod circles agreed with the findings.

Now you know.
