Well i dont agree with you on there not being a value to it. Ait temps are very crucial to the power you make.

As far picking up water, with a turbo that generally isnt an issues because the turbo will atomize the water with the air. In fact many high hp cars do this intentionally to lower intake temps. Now if your submerging the filter underwater as you drive.....you have driving issues. I have been caught in many downpours as have many of my friends and if you search the internet, its not an issue liek you think it is.
