Injen Short Ram Intake
Intro
So I received my intake this morning from the post office. Apparently it's been sitting there for the past two weeks and no one told me. Thanks goes to Kevin at US Autotech for the great deal and super quick shipping. I think he still has a bunch left so get yours now before they run out!
Just to note out, my G is a 2nd G35 sedan.
Pre-Install Check
Now on to the intake. Everything was very well packed and covered with that brown paper stuff to prevent any damage. The Amsoil EA filters provided are excellent. They felt very well made and looked better than the oiled gauze paper IMO. The tubes were also super nice with a shiny finish on the outside and very clean welds around the MAF sensor mounts. The inside however seems to be a little left out. The hole where the MAF sensor goes looks as if someone took a dremel and just made a quick hack job. It does not alter performance or hinder it in any way, however, for those who are **** about looks this may be a slight issue for you. I am, however, completely satisfied, considering the sensor location on the left and right intake tubes are perfectly aligned.
Installation
The installation instructions were pretty good and goes over the entire install without missing anything. There were more pictures than words which I prefer. However, the pics were relatively small and could certainly be even more helpful if they were bigger. Moving on. Half of the install procedure is done prior to opening the hood. You will first need to install the velocity stacks into the intakes, mount the shields onto the intakes and the slip in the tubes and mount the rubber insulation. At this point, everything was a perfect fit. I was however not sure of the rubber insulation, since I had an extra piece left over that was not included in the pictures. Oh well.
Removing the stock intakes is very simple and is outlined in the instructions. Once i removed them, I also took out the stock silencers. They were sitting there down nothing. Removing them helps reduce clutter, ease access down there and avoid future rattles and such. There's really not much to say about the install since it's a simply in and out procedure. Although I will comment on a couple things. First, the heat shields line up with the mounting points nicely. everything fit nice and tight with no moving around. The only thing that bothered me with the install is the driver's side intake tube. The darn thing will not stay put when tightening the bolts! It will either slip inside towards the filter or go the other way into the rubber upper tube. I had to slowly tighten both upper and lower bolts while holding the tube to get a good fit. Other than that, it was all good and took about an hour total time.
Testing
So far I have only put about 40kms (~25miles) on the car since the install so I can't really comment at the moment. One thing i immediately noticed though, it seems to drive smoother when cruising around. I do not attribute this to disconnecting the negative battery terminal since I've reset the ECU many times before and this never happened.
I will update this thread as I get more time on the road. The ambient temp is 130F in the day and 110 at night with dust storms most of the time for the past month or so. This should be the ultimate test for these intakes.
Comments and opinions are welcome.

You have an pics of the silencers you removed? Not sure what that part is, also i had the same problem with mine and drove me crazy with the clamp that tightens around the polished tube facing the sensor. Tighten it and it either pushes the tube into the filteer or out. I hope it wont pop out during use. I feel it is just hanging on barely. Anyone have any ideas how to fix this problem?

blkmanual, heres some pics
Silencers
Here's where they connect with the stock boxes
When I had my SRI I had a friend hold the intake where I wanted it, while I slowly tightened the clamp down all the way. I never had any issues with it. My friend now has my SRI and we did the same thing for his car. He's driven at least 10K miles since and no issues either.

I dont think I had those on my car. Are they on the convertible? I dont recall seeing anything like that. I did exactly what you did I installed the entire unit and then tightened the clamp while it was in place I just felt it wasnt ssecure as if you tighten it down at a certain point it either goes inside or pushes back out. Maybe I am attempting to tighten it too much? Thanks for the picture.

My car is a 2008 G35 HR sedan. I'm not sure if the G37 has the same silencers or not. Just take a flashlight under the filters and check to see if they're there.

Thanks so much for the great review Q8y_drifter, this thread sealed the deal for me 
Just installed it today and love the mean growl above 4k rpm. Thought my G sounded pretty good w/ my exhaust but now it sounds angry
Got a nice deal on Ebay, guy drops the price every few days so if you're interested just wait a bit and you should get it for $279, got it in 3 days too!

Install was simple, hardest part was getting the 4 bolts into the velocity stacks. Not sure if it's common but the inside threads in the stack had some plastic overrun into the threads so I ended up using a tap to clean them up so the bolts wouldn't cross thread. Other than that the quality & fitment is very good. I too had the same issue as the OP regarding the rubber sleeve wanting to slide off the "hump" on the drivers side. Just takes a bit of trial and error to get it just right then really clamp it tight, seems to be staying put. I too removed the silencers, just a metal clip holding them in and you need a long flat screwdriver to pry so you can slide them off, not sure how easy they'll be to re-install but I'll hit that bridge when I come to it. Here's some pics of the install. Thanks again Q8y_drifter!
