How do the Baffles work in the RamAir,either AiRaid or the Hood scoop, to keep the water out??
I mean wouldn't that kind of be non-productive/working against the air intake, rerouting and taking away from the overall intake of incoming air, and swirlling it to much before it gets to the filter??
I'm worried about water messing up the filter it self as well as getting in the engine.

Now, some people, well the ones who do not drive in the rain, cut the baffle out. Being a former WS6 owner I knew a couple who did this. They even hit occasional rain and never had issues. However they dynoed before and after with less than 2 HP gain with a cut baffle, although you generally would see better results on the road when you are moving.

Got the exact same CAI in my '05 Ram Daytona. Make sure when you install it, you keep it 1/2" to 3/4" from the hood. I had to modify the air box support arm to make sure I had the proper clearance. Definitely got a rub on the hood, however copper rustoleum does wonders. No indication of rain/water getting in the airbox. Good luck!!!

You do realize that the only benefit to "Ram Air" in your rig or any muscle car is/was just cold air? HP changes 1% for every 11 degrees F change in intake air temperature...I will quote a friends site for this info here...

Assume for a moment that the outside air temp is 70F and the underhood air temp is 170F. Air density is related by the formula:
doa = square root[(460 + tuh)/(460 + toa)] x duha
where
doa = density outside air
duha = density underhood air
toa = temperature outside air
tua = temperature underhood air
therefore: doa = square root[(460 + 170)/(460 + 70)] x duha
doa = square root[ 1.19 ] x duha
doa = 1.09duha (well duh...sorry, couldn't resist)
( Note: the 460 in the equation allows the use of degrees F instead of having to convert everything to degrees Kelvin, absolute. )
So, outside air density is 109% of underhood air density, or 9% greater. Because mass air flow increases in direct proportion with density, HP produced with the cooler outside air will increase 9%. Therefore, an engine that produces 200HP with 170F air will produce 218HP with 70F air.
