Just curious as to what the difference between the air intakes that sit right up in the engine bay and require a heat shield vs. the ones that run out and down into the bumper? only thing i hear is "water might get in it" other that that does one give more airflow or better air flow? Thanks.

the ones that sit in the bumper are cold air intakes, key word being cold as in away from the hot engine.
short ram intakes sit in the bay and sometimes have a bit of a heat shield that helps keep heat away but aren't as effective.
if you're car is turbo'd there is no point in a cold air intake or a shielded intake because the air gets hot as soon as it reaches the turbo.

Sorry, i just have to differ, a turbo with CAI wil always run better than a turbo with a WAI, the propellers work at less RPMs and actually the engine profuces better power
I had a Short Ram and when i went for the CAI i could feel the engine running better

May I attempt to sway your opinion?
1) Cooler air readings at the MAF give the IAT a tick more engine timing. No arguing that.
2) Cooler air is always cooler air. For example, the air that enters from a SRI is 100º(made up number) and gets heated up by the turbo 25º(another made up number) for a total of 125º. Air that enters from a CAI is 75º, and gets heated up 25º for a total of 100º.
However, since colder air is more compressed, it might reduce the spool. I can't say for sure though, I'm N/A.
Just my two cents!
And we can say cooler already turbo-compressed air reduces the work on the intercooler, making it more effective
Cheers again :beer:

Um, I'm not sure on that one. The laws of thermodynamics wouldn't agree with that. It won't hypercool the air, maybe just a little bit. It's hard to explain, English isn't my first language so that's no help, but the degree of extra cooling has diminishing returns. Since intercoolers are made out of aluminum, their effective temperature is typically 10º lower than ambient. They're incredibly efficient on their own.
Both of these seem like very good assessments, but it's about the physics of it. Are we sure that there's only to be a static x° rise, relative to the ambient temperature?
For instance, the end-air from the air compressors at my job always run at the same temperature year-round unless the radiator is outside of the plant (then of course in winter the system runs more effenciently.) This would imply that cooling the air after compression makes for a more efficient system (that that's why we have FMIC's.)
One the other hand, if you put water in a tea pot and heat it for 5 minutes, then yes, your ending temperature is going to differ depending on what it was when you started.
I'm not sure that air compression follows the same rules as the latter example. Worth some research, though, since there are some that swear by CAI's.

Yes but it may reduce the chances of overheating the IC... happens to me on my Stock IC, pisses me off so im changing it this week :thumbup:
So this is our conclusion: CAI is better, you cant go wrong with CAI :beer:

i also wouldnt say that. but who cares.
OP, chances are whether you get a sri or cai or even keep your stock airbox and put a k&n drop-in in it, you probably won't notice a difference in drving other than the noise. If you want to spend a bunch of money on a cai kit and piping, go for it. it's your stuff
Oh , come on CAIs are not that expensieve

Solution, put the turbo down where a CAI filter would go :laugh:Both of these seem like very good assessments, but it's about the physics of it. Are we sure that there's only to be a static x° rise, relative to the ambient temperature?
