I went K&N for three reasons; for one it had awesome and honest hp gains, two it's very likely that it will eventually be smog legal in CA, and three it's a nice alternative to a true CAI. I don't want to run a true CAI because I drive up to 400 miles a day for work. So puddles are very common and I'd rather be safe then sorry.
