Question on CAI's.

Over the weekend I had some interesting things come up. We had a mazda meet out here for all the Phoenix Metro Protege owners. There we met up with the owner of RM motorsports and I was able to see first hand their new CAI for the protge. It is awesome!

We got into somewhat of a debate on whether or not a CAI would benefit a turbo car. He said it would, while me and my friend didn't think it would. We think that since the air comming in get so hot from the turbo that it doesn't really matter what temperature it is by the time it gets to the IC- Unless of course it's a 50-100 temp difference.

That night Jason at RM gave me some of their flexible hose that they use for their CAI. Yesterday I replaced my ghetto hose with some of the stuff they used, and since I had so much extra I thought it would be fun to play around with it. I ended up putting my K&N filter on the end of the extra hose and stuck it down in my wheel fender (where the Injen CAI's go). I spoke to Jason and through his testing in the summer he found over a 50 degree difference from the area I originally had my filter, to where it was now.

I've driven my car quite a bit since yesterday and it has seemed to have helped a bit. Not initially, but after the car has been running for a while and heat builds up in the engine and engine bay area, it seems to still pull hard- where it used to decrease in performance.

Any thoughts on this?
 
I put mine there also. I didn't realy feel a difference though. I' a little worried since it seems to get very wet in there, as I discovered last night.
 
Yikes... I guess it just depends where you live... Out ehre there's rarely any rain. Plus during the summer it get's CRAZY hot out here and the temp difference could be very large.
 
Well we had 5 inches of snow this weekend so its soaked everywhere now that the temps around 40-45 and its melting off.
 
why doesn't somebody just make a heat shield for the CAI???....i've looked around and no one makes a CAI for the protege with a heat shield....i'm sure you could make one yourself....but you'd think someone would have done it already
 
The injen and MHP put th intake down by the tire well so the cars body metal acts as a heat sheild.
