Actually, I came into this thread about that. I'm pretty shocked because they did make a difference. The motor doesn't sound so wheezy and strained anymore, it actually sounds lower pitched - more like the 350Z did. I swapped the OEM filters back, and the wheezy/high pitched tone came back (this is very evident to me in lower RPMs). I put the K&Ns back, and the tone changed again.
So if you don't like the sound of the motor and are looking for a quick change, definitely drop these in - they make just the right improvement in sound.
There's a teeny bit improvement in power, but it's mostly low-end and you have to be pretty sensitive to feel it.
