I'll look into the A/F chart later, but atleast 2 members had it.
First off, did the 370z have any mods, custom tune? I'm not really familar with the 370z set up so it's hard to say why the A/F ratio is within factory, but its basic physics my man.
The location of the filters is similar to putting your head outside a window going 60MPG+, its hard to breathe right? The dramatic spikes in the A/F chart with the 3G when one is idle and WOT is incredible, and I mean incredibly horrible. I'll dig up those charts later.
Even Church Tuning (well known tuning shop for VQ's) noticed that my A/F ratio was a bit high, but I totally forget to ask him to print out the sheets for me when I was dynoing my G with the Stillens.
Why do you think Injen changed their design before? Injen had their design EXACTLY the same as Stillen 3G, but noticed the problems with it, therefore changing their set up.
Put aside the mystery A/F ratio for the 3G, the quality alone and fitment is enough to scare me away as a buyer.

. i'm just blown away...
I know right...E46 M3 + CSL airbox for the win....close second though is a 37 + injen/stillen 3gs...i'm so jealous everytime i ride in my friends car with his 3G...i hate him.

I guess I found it! and yes the AFRS can get close to 14s...
Below is an article by mike kojima on his tests on the stillen 3g on a 370Z. he first did the test with the bumper on (which encloses the filters) that net them a gain of 9whp. With the bumper off (which exposes the filters much like it does with our G37s) he got a goin of 15whp and leaned out his AFR (see last dyno sheet in the link below).

Well some people are too damn sensitive about the whole intake subject and think it's probably the best mod and it adds like 30+whp lol, it's not a damn forced induction car to do that. Anyways, even with all the bolt on mods, and a nice tune, it should be enoughh to fulfillyour craving for more power, but personally I wouldn't waste your money. Infiniti has done a great job and squeezed every ounce of HP out of this motor.
On a side note, people say a full catback exhaust is good throughout the RPM chart, not true, look at the low-end power and it some cases its a loss or the same.
Probably best first performance mod would be HFC's, haven't seen any real con's with those besides the installation and the O2 sensors.

dude I told you to send a me a link for those, I want those and the side vents too! and I want that ebay chip that adds 80+ whp, then I need some resistance and downforce power, so I'm gonna put a 10 foot yellow spoiler on my trunk

I mention this to you in a previous post about the 370z bumper blocking the filter. see this post I post to you

i agree. but modding is a lot of fun and it's hard to keep a stock car. i have had first rate experience with full exhausts and headers. i found the more n/a breathing mods i added the leaner my afr, thus the ecu pulling timing and not sending enough fuel. once i got the reflash from tadashi to richen up my power was back up...and then some. even a simple change like a header wrecked my afr. with an intake, pulley, plenum spacer, exhaust my afr was a straight through 13.5 @ 243whp....i added a header and my afr was at mid 14s throughout the band @ 243whp
Tadashi pulled my plugs and found aluminum filings...my car was detonating which was why my car was pulling timing to prevent further damage to my motor at WOT, resulting in the loss of power. he richend up my afr and got me back to low-mid 13s @ 252whp. so from a cost point of view it doesn't make sense to go n/a since my baseline was 220whp. but it was fun...all that counts i guess...LOL.

of course on the same post you admitted you didn't know anything so it cancels out...lol
