The G3 made a whopping 22 HP more than the R2C. Yeah, the R2C is better under the curve, but you're paying a lot for a little under the curve power. I'm skeptical that WAI do anything, as Stillen claims a 20HP gain over stock with their CAI. If it picks up that much compared to the R2C, that would imply that the R2C is roughly the equivalent to stock. The fact that R2C put all the R&D into an intake, and didn't dyno the gains leads me to believe there aren't much--aside from intake noise. Which is cool
The post MAF tube/drop in filter mod is full of win. And I personally believe there may be another bottleneck in the stock system that can be addressed for little cost but I digress.
It won't win any beauty contests at the car show and may not score the highest dyno numbers (like the Stealin' G3 CAI), but damn does it improve the drive-ability of the car IMHO at a low cost.
And that in and of itself is worth the price of admission.
post maf tubes with afe filters and art pipes got me 300 to the wheels. ^_^
Tuned or not tuned? I made untuned 300WHP with Takeda cold air and FI RHFC's on my 11 X Coupe. I know have a 09 X sedan with Z1 tubes with KN drop ins stock cats an will be back at the dyno after my eTUNE from Motion lab.

Curious what you think this bottleneck might be? Because I agree in theory that there is another bottleneck that could be addressed for little to no cost

funny, I just switched back to the oem tubes with aFe drop ins. The car actually seems to really like this set up. Very smooth power and instant power at that. Part of it is bc of my tune, but still.
I installed the Mishimoto intake tubes yesterday and had a rough time doing so. The first issue I ran into was the passenger side not fitting properly. The smaller tube off to the side was too long and was preventing the tube from fitting right. I had to take a razor blade and cut off about 1/2 inch from that smaller tube, which was fairly easy and it now fits snug.
I think Mishimoto's test car is off or something. In almost every 370z and G37 thread I've read about installing these tubes, the owner had to trim the piece I'm talking about, which IMO indicates poor quality control. There may be a reason for this piece not fitting, so I'd be interested in hearing any rebuttals.
The second issue, which had me worried for a bit there, was that I broke off a plastic connector on the driver's side that connects an air line from the engine to the smaller tube hanging off the side of the intake tube (pictured below).
I **** my pants a bit when this happened. I guess my hand was pressed against the connector as I tried to maneuver the intake tube in place, which caused it to snap in half. I ended up going to O'Reilly and getting a 90 elbow coupling which fit pretty nicely. The part I replaced was essentially just a 90 elbow coupling with a large box attached to it, but no valves or anything - it's just straight through. The coupling saved the day.
I also ended up reusing the OEM hose clamps since the ones included had something wrong with the bolt threading and I couldn't get the nut past a certain point in the thread. Oh well, the stock clamps are easier to work with anywho.
I'm pretty pleased with the final result. No CEL and everything is running smoothly. I replaced two cracked intake tubes and why I don't really notice any difference in performance, the intake sound is a bit more throaty. The engine bay also looks cleaner IMO. If you want to improve the intake sound a bit, dress up the engine bay, or replace OEM cracked tubes, I'd say it's a worthy mod.
I genuinely enjoyed reading this old thread, seeing familiar SN's, realizing this was all 4-5 years ago. And OMG the OP could really take good photos. I miss that now that he's moved on.

Marginally, perhaps. If you cleaned all the plastics as well as Dragion did, the flex tube would look just fine.
Calling out "looks" as an add to a priority of performance is a fair argument, but I think if how it looks is a consideration on the radar even a little bit, then you should just get a decent intake kit. That giant white M, times two, on glossy wrapped couplers... I think there's as good an argument against good looks as there is for it.
