Wouldn't the the plastic piece that fits in the wheel-well protect it from wet wheels? Mine does :dunno:

I went a step further with my CAI. I made use of the resonator to house the filter. I then fabricated a scoop and mounted it to the front of the resonator so that at highway speeds air is somewhat 'forced' into the intake system. I don't get the kind of pressure that you would from a forced induction system (turbo or SC), and it isn't enough to require re-tuning the ECU. The theory seems to work and only at speeds greater than 40mph; not alot of gain, but enough for me to notice the difference.
