Personally I wouldn't install a cone style filter.  Part of the
reason for the air box is provide cleaner COOLER air from elsewhere. 
The engine compartment is dirty and wet and a cone filter will not protect
you from a good water splash and it will get dirtier faster with all the
road crap being kicked up.  Also, the cooler the air is there more
air there is at a given volume.  As we are running a AFM and not a
MAF there is no way for the system to tell how dense the air is - so yeah
the CARB guys and other people who do that kind of checking won't be happy
- even though technically the O2 sensor should look after this by leanin
gout the mixture which means you will loose power with warm air too. 
They also act as a muffler - step on it and your 2.1 will growl loudly -
yeah teenager cool sound, but really... 

Just one of many
reasons why I don't run cone filters that are out side of an air box.
