The debate is as old as Ford Vs Holden.. I have had both and notice bugger all difference between the two, though the CAI will get colder air (Just!) however its marginally harder to fit - generally remove passenger wheel and guard lining.
*Stickied*
Yeah the debate is very old.
I had a CES SRI with heat shield, i noticed that the car felt more responsive at low rpms and the induction noise was a lot louder.
Now i have a Mazdaspeed CAI, not as responsive (maybe because the pipe is slightly longer), sound is quieter, but more responsive at higher rpms.
I've got a hydroshield wrap over my filter just to prevent water splashes (keyword "splashes") but i don't think water could get to the filter *touch wood* because the mazdaspeed CAI doesn't sit that low. It actually sits above the stock airbox resonator, it sits JUST under the engine bay.
Old debate. I'm sure there are a few threads on it. I know I've made a number of comments on it in various threads before. In short I figure CAI's are a waste of time and space, are a headache to service and a water induction worry for those who like to go wading and a dust induction worry for those who want to cross the Simpson. Just my view.
But a comparative infra-red temp probe on the turbo intakes immediately after a run with both will prove the point pretty well. If one was totally anal about getting coldest possible air to the intake, I'd prefer to feed cold air from the grill area direct to an airbox wrapped around an SRI than mess about with all the extended plumbing on a CAI and put up with the other attendant issues I've referred to.

Pfft, filter...what filter?! SRI, CAI or none!
Did i miss something andre? is that a response to my comment? if it was i don't get what you're talking about
SRI vs CAI debate, use no filter, although not recommended! Wasn't a response to any comment lol
Ever seen a dusted engine ROG? ;o)
Solved
Big enough to ingest the entire sealed road in front of you!! ;o)

I recently learnt what VTEC is Virtually Torqueless Economic Car
Not sure I would want to brag my VTEC kicked in! Then again, Honda RAM-AIR intake FTW
A ram-air intake is any intake design which uses the dynamic air pressure created by vehicle motion to increase the static air pressure inside of the intake manifold on an engine, thus allowing a greater massflow through the engine and hence increasing engine power.
The ram air intake works by reducing the intake air velocity by increasing the cross sectional area of the intake ducting. When gas velocity goes down the dynamic pressure is reduced while the static pressure is increased. The increased static pressure in the plenum chamber has a positive effect on engine power, both because of the pressure itself and the increased air density this higher pressure gives.
Ram-air systems are used on high performance vehicles, most often on motorcycles and race cars. Ram-air has been a feature on some cars since the late sixties, but fell out of favor in the seventies, and has only recently made a comeback. Modern parachutes use a ram-air system to pressurize a series of cells to provide the aerofoil shape.

Thats awesome, imagine somehow removing the foglight area on the MPS6 or 3 and just have a Pod sitting there :O

Ram air is of no real benefit to a turbocharged engine, aside from the cooler air factor the turbo is a ram device itself.
Yeah true, I was planning colder air!
The mild benefit of "ram-air" lies in ensuring that the air is there on hand for the turbo to utilize effectively. A similar principle though far more positive approach lies in having a supercharger over a turbocharger, as in many diesels, especially two-strokes and often in marine engines where engine compartment venting can be restrictive if not correctly designed, and is often far too hot for best efficiency without adequate venting.
The obvious converse which serves to prove the point would be, say, a blocked air filter, which denies the design airflow to the turbo.
