Looks are great, there isn't much of a whistle, I feel a slight difference in mpg and throttle respone. I had a bit of trouble installing this on my 2006 350z cause I have the aftermarket K&N cold air intake, the hardest part was putting the line back on underneath the K&N but from there it easy, I took a good hour to install. I would recommend this product to anybody that has a 350z. I was reading some other review on this product, saying that it threws off the Rpm's, I hadn't felt anything.

The spacer itself doesn't seem like it was built for 350z, it throws your throttle sensor out of whack and whenever you let of the throttle with 2-4k rpm it literally feels like you are braking because the throttle body close down so hard. And this can only be fixed with a new throttle body.
