I posted this originally over on infitifx.org but I figure that I would share it here as well.
Here is a link to the same kit that I bought:

The reason for getting the intake is that my air filter needed to be changed. Rather than spend the $40 on a decent panel filter, I decided I would try out an intake. Plus, my FX gets terrible gas mileage as it only sees city driving (16-17mpg). I was hoping that the intake will give me another .5-1.0 mpg increase which will make it worthwhile.
I know a lot of you will say things like, "ebay stuff is crap" or "I would never buy parts off ebay." That's fine and you're entitled to your opinion. I have had a lot of success (luck) buying parts off ebay in the past. After some research on the VQ35, and my experience with modding other cars, I have come to the conclusion that this intake, like most of the others, is just a 3" aluminum tube which I can't justify spending $200 on.
Installed it on October 9th and haven't had a single problem with it since. Here are some pictures:




Overall, the fit on this thing is pretty good. Even though I had an extra K&N cone filter in my garage, I ended up staying with the supplied filter because it is actually quite nice. The install took about 45 minutes. 15 minutes of that was spent trying to find the correct angle for the rubber throttle body connector so that I could get the intake filter to sit up against the intake ramp (see pics).
The best part about it: $26 shipped!!!! I feel sorry for all of you who bought the $150-$200 intakes.
Since the install, I have noticed about a .5 to 1.0 mpg increase in fuel economy. I didn't really notice any power but I had expected that. Modding NA cars up here at altitude is pretty pointless. The noise was increased a bit at WOT but, when cruising around, it sounds stock. Overall, I am very happy with my $26 (shipped) intake!
