09 G37: Stillen Gen 3 Cold Air Intake + Grounding Kit installed (+ dynos!!)

Hey guys

This is my attempt at making my first post a useful one so let's get down to business:

1- Stillen Gen 3 Cold air intake:

Pros: awesome gains across the band, sexy growl, imo: best (reasonably priced) $/hp upgrade for the G37
Cons: A real Pain to install if doing it urself... otherwise, nothing else

2- Stillen Grounding kit:
I would like to talk a bit more about this upgrade since I previously owned a 2008 (5-spd) G37 before my current 2009 (7-speed) G37 and one of the things I disliked was the lag in shift time response. Of course, I'm not expecting GT-R spec shift times, but there was a noticeable lag which was more like a hesitance as the car tries to select the 'optimal' gear.

In short: the ground kit basically made it feel like a new car to me.

No more 'wait for the car to make up it's mind' moments as my foot steps down on the aluminum gas pedal..

No more 'hit the paddle shifts ~500rpm earlier in anticipation for the upcoming gear upshift..

so for those of you who share my problem, I highly recommend the ground kit solution!

replying to some of your questions:
1- Honestly, I don't think there's much of a difference in choosing stillen vs black betty grounding kits since both kits seem to be very good at what they do. In my case, i just saved a bit on shipping since i was ordering the intakes from stillen at the same time..
2- I believe it was dyno'd at 5th gear
3- growling was most enjoyable in 3-4k rpm @ WOT.. nothing that would wake up the neighborhood though..
4- intake gave the hp's.. grounding smoothed the transition from engine to tarmac
5- I think I'm still within good limits (as far as the dyno guy said) in terms of A/F ratio..
no detonation as far as I can tell.

Update: Just did a 420 mile trip today from AZ to CA with a heavy rainstorm in CA.. All systems green so far, and the intakes seem to be handling the rain quite well. Hope it stays that way!

Did you need to make any ECU programming?

Please invest in a tune, you're running over 15:1 at top RPMs.

His afr is at 12.5 below 3500 and is dancing on 12 from 5500 and on. i think he's fine. a tune would just polish it up.


...still 29.6 hp from an intake is really hard to swallow. the median gains from the stillen are from 12-18 from G37s and 370s...of course it doesn't reallay matter what the number is, he has his delta and gains across the curve. i guess that's what really counts. congrats

Just a quick question: how come it says under the customer line item on the dyno, 08 G37 for the base and the 09 G35 for the intakes? Is this just a weird error entered or was the base on your 08?

Just noticed that and wondered... Awesome gains though!
