As I promised, here's an update/impressions on these CAIs, after having driven for few weeks with them installed.
First thing first, :pics:

They look very good in the engine bay :tup:
Here are my impressions overall
Installation time: took me a while, mostly because of the air duct cutting... yeah I know it should be easy and quick, but I wanted to do a good job so I first cut them and then started enlarging the holes until the rubber hose was comfortably fitting with no restrictions.
2013 Bumper removal: this was quite a PITA. Having DRLs made this a challenge for someone who's never removed a bumper... I had to get the wheels and the front fenders off to easy access the DRLs, unbolt them, wrap them in bubbly plastic and tape them to the brakes. Then I could easily remove the bumper.
Feeling: these CAIs are a great choice for a DD. I currently have them on stock engine, stock exhaust and no tune (S-Line mode). They are quiet on low RPMs, but they start coming alive around 3000rpm and open up at >3500rpm. Performance wise I can only speak about butt-dyno, as I am waiting on my full exhaust+tune to actually get a new dyno, but the engine definitely feels more responsive on mid-RPMs. Of course, I've never expected miracles from a stock car with CAI, neither should you :)
Pros:- Big, these pipes are big! It's pretty awesome that they come in S-Line (no tune needed) and R-Line (tune necessary) with a max of 2.75" tubing diameter. Air Flow FTW!!
- Rubber hoses go through the cut air ducts, this way it's easier to adjust the fitting and, guess what, you have rubber over A/C lines! This comes with a price though, and you have to enlarge the holes a lot!
- You can butt-feel the gains.
- AAM offers an awesome customer support, Khoi@AAM is very active on the forum and always offering help and support (also with my ranting about G3 Vs AAM), sorry about that Khoi :rofl2:
Cons:- Installation instructions. Available at their website, instructions are not very descriptive and IMHO skip a lot of steps, some of which important like cutting the air ducts on the driver's side, which is a slightly different approach because of the infamous A/C lines, removing the crash bar, dealing with the cable running in front of the bumper. I *HIGHLY* recommend to follow and integrate those with ak370z's DIY on Stillen G3's installation here: http://www.the370z.com/diy-section-d...de-ak370z.html
- Clearance. Were you seriously expecting 2.75'' pipes to have good clearance? C'mon... - On the passanger's side there is 1/4 inch between the main pipe and the crash bar. On the front, there's a metal bar on which a cable is running along where the bumper gets clipped to that has 3 bolts; the central one will go back in, the 2 bolts on the side will not fit anymore because they are too long, so I had to ziptie instead. I also had to wrap some rubber on the final metal pipe to avoid rattles against some metal supports. (did anybody actually understand any of this?...). Anyway, here's a picture of the cutting done on the driver's side
- If I have to be extremely picky (did anyone say freak?), the kit came with a wrong smaller metal clamp that wasn't fitting. Not really a big deal as I re-used the ones from the stock intakes... but still... :rolleyes:
Overall, I like these and I feel to highly suggest them as a perfect alternative to the pricey and obvious and hyper-branded Stillen G3s. :driving:
