AEM now makes a bypass valve that you can put on the cold air intake.
IF/when water becomes a problem and it gets sucked up the tube where
injestion could happen, the valve automagically opens and the vaccum
created in the pipe is gone, leaving the water to spill out of the
filter. Your engine keeps going due to it being able to pull in air
through this valve under the hood. Its covered with filter matrial
too so you wont pull in dirty air. Price is about $40
Ive run a cold air intake like the AEM on a 95 Impala SS (350-LT1 V8)
where the filter was behind a splash guard about 6" off the ground.
The filter got wet after several hundred miles in the rain and
sometimes would be soaked enough that I couldnt pull enough air past
3,500 rpms but on that motor, thats a LOT of air. After a few hundred
miles it would dry out. I always Rewashed and oiled the filter though
if I had to drive in heavy rain. Even so I Never had a problem with
water entering the Throttle body or the motor. Though if you submerge
the filter you WILL.
I ran a similar setup on a 94 Trans Am, same motor. The splash
pan/guards were a lot better on that car as far as protecting the
filter and I never had a problem in rain EVER.
The CRV looks to have pretty good water protection in the filter area
and its up rather high. the chances of submerging that or picking up
enough water to pull into the engine is pretty slim IMO. Personally
though, Id get the bypass valve as cheap insurance.
The intake setup wont void your warranty, unless you drown your motor.
but SALTMAN gives the best advice when he says to replace the stock
intake at least partially (airbox and pipe to manifold) when you take
it to the dealer for something engine related. By law, no aftermarket
part with a CARB # and SEMA approved can void your warranty unless the
dealer can prove it did, but 9/10 times they will use the intake as
the excuse for whatever problem you have.
FYI: the 97-98 AEM cold air intake doesnt fit perfectly on the 99-2001
CRV but Im told the one for the Civic SI is a perfect fit.

modifications.
