Partly true. CAI's make most of the HP by "Resonance Effect".

Because CAI's make more HP.

No. Water will get in.

Depends. How strong is the scoop?

You're on your own there.

It would be kind of hard to dyno a hood scoop.
A while back,I had a hood scoop from a '85 Turbo 300ZX on my NX2000. Now I'm
using the PR CAI. The difference is night and day! The CAI works WAY better
than my hood scoop ever could. And while I'm thinking about it,there's
another factor to consider. Aerodynamics. When I had my hood scoop,I noticed
that at high speeds,there was a tendency for the hood to start to lift up on
the hinges. If I would have kept my hood scoop,I would have had to invest in
a set of hood pins in order to prevent the hood from flying up into my
windshield.

When it rains,just short stack the CAI and you won't have a problem.
