I have a K&N on my 06 ST and i couldnt be happier. I put it on about 2 years ago and ive never had a problem with hydrolocking or any issues with water for the matter. My stock splash shield is holding up just fine but I also have the water repelant "sleeve" on it. My vote is with the K&N for sure. Sounds great too!
