After dealing with the installation completely, I've come to see more clearly several issues that trouble me about the system. 1) HEAT: even though it is sucking air away from the engine, the air still needs to travel through extremely hot pipes (the insulated stock plastic doesn't pose this problem), so the resulting benefits of cold-air are dubious 2) AIR: I removed the plastic fog cover pieces. As you can see, the filters are quite visible and are openly in danger of water exposure and vandalism. The WW fluid reservoir is also undeniably visible, and I would think impedes upon the air flow of the adjacent filter, which may cause an imbalance in incoming air for each side.
Also, if the covers are not removed, then I cannot see much air reaching that very enclosed area, compared with the stock air-intake openings near the grille 3) WATER: hydrolock threat - enough said. Suffice it to say that I will go back to the stock intake during the rainy season.
- I've been waiting for this thing for weeks. My Tanabe mufflers and y-pipe, as well as my Berks have been sitting idly, because I wanted to test this item completely alone on the car. Since I've been patient this long, after the runs on Thursday evening, I will look into other simple avenues of extracting more power out of the Injen alone, aiming to reduce the aforementioned issues.
After reading Herrjr updated review of the injens, The part that is highlighted above which is his words is what I have said in my previous posts. Obviously you are not going to keep the vents off on the bottom of the car so in return there is not going to be enough air to be able to get into the filters. Just like I said......., the only other person who said something about the air after my post was bboy. The car needs air to run. So with that, I am done with this injen conversation......

Alright, I finished installing the Injen, and my dyno appointment is set for this evening, so I'm setting the stage for posting the results later:
Baseline conditions:
-all stock G37S 6MT
-Mustang Dyno
-sea level
-temp in 60s
-humidity unknown
-91 oct Chevron CA blend
3rd run with VDC off:
Average A/F of 11.6:
Injen Dyno conditions:
-all stock G37S 6MT + Injen only
-Mustang Dyno (same)
-sea level
-temp TBD
-humidity TBD
-91 oct Chevron CA blend + a couple gallons of VP 100oct resulting in 93 final oct
-lower fog lamp covers removed
Update #1:
Ok, sorry to excite everyone and have you all wait, but I had stuff after the testing and wanted to provide the results in proper context, so I had to wait to get home.
RESULT:
- Even with around a 30+ change in temperature and a likely similar proportional change in humidity, there was a gain in peak HP and a drop in peak TQ.
- Each run resulted in more power; if I had more cash to burn I would have run the recommended 7-8 runs.
- The average A/F ratio dropped, from 11.6 down to 11.1.
Issues:
- Resetting the ECU was not as simple as I would have liked. I could not accomplish the "method," so I simply unplugged the ECU. The problem is, this was done just before the dyno-testing. I only had a chance to drive around the block a little, so I did not have an opportunity to go at high rpm past second gear.
- Based upon the A/F ratio indicating a richer mix, I believe that the ECU was not calibrated well enough compared to its status during the baseline runs.
- It was 90+ degrees ambient temp. at around 7pm at night. The intake pipes were too hot to touch, and were still very hot after hours of the engine being off.
Conclusions:
- Based upon the weather report, in two nights it will be much cooler at the dyno location, so I can get closer to the temps of the baseline runs. I will dyno it again that evening.
- I will clear out my fuel supply, and return to 91 oct Chevron CA blend only, to cancel out any discrepancies caused by the racing fuel.
- In between now and Thursday evening, I will floor it every chance I can safely and legally do so, to have the ECU hopefully more primed.
- Until the runs Thursday evening, I will not be posting any charts of the Injen runs.
Personal Remarks:
- The intake really does sound amazing. After 3500 rpms, it just transforms the car into a total beast sound-wise.
- For those that said this intake would be their only mod, I would seriously suggest that you reconsider that position, unless your main goal is to have something that looks and sounds badass, as opposed to simply adding performance (in which case HFCs or TPs are the overall best way to go).

Till Thursday. In the meantime, I'm gonna cry about how I still haven't removed my stock shift ****. Bloody thing is like a Sisyphean nightmare - it keeps turning, and turning...

Well since we have no results, let me dive into some of your updates if I may.
- Even with around a 30+ change in temperature and a likely similar proportional change in humidity, there was a gain in peak HP and a drop in peak TQ.
>> Can you at least give us a hint as to what these numbers were? Good or Bad.
- Each run resulted in more power
>> I think you would have seen this on the stock runs too. Which makes sense as the car loosens up.
- The average A/F ratio dropped, from 11.6 down to 11.1
>>
- I will clear out my fuel supply, and return to 91 oct Chevron CA blend only
>> This is a good move and will remove doubts on the results
- Until the runs Thursday evening, I will not be posting any charts of the Injen runs
>> Ah come on, you listed the conditions and stipulations, post them and then repost when you re-run.
- I removed the plastic fog cover pieces
>> I understand why you did this but no one will drive around like that. Have to wonder if that changes the results too....as far as incoming air temp.
As to your other comments, overall, it sounds to me like you are not all that happy with the system. You have concerns about heat, filter location, hydro lock, etc.
We do appreciate your input and willingness to spend the time and money to do this so the rest of us can evaluate things and make our own decisions based upon the results provided by folks like you.
Thanks!!!

yea Max you missed ALOT....this thread was out of control last night and it was a post deleting massacre.
anyway...im gonna try and fabricate a new screen or some thing for the plastic covers. maybe dremel out the plastic mesh webbing and install a simple black screening behind plastic cover. In either way...hydrolock is a threat. Now im also alittle bit anxious about something else...On long trips, like 4 plus hours, these intakes are getta HOT and make the engine bay VERY HOT. Did Injen R&D this long enough???? i doubt it

I cant believe that he is not posting the dynos and numbers... This has to be because "Someone" has got to him FIRST... and told him not to post cause it will hurt there Sales... I had similiar calls about my injen as well...
I think its pretty cowardly not to post the numbers... by doing that you are saying you dont give a **** about the myg37 members and you dont wanna help everyone out...
You stepped up... now WALK all that Talk of "Im dynoing ASAP"

Whatever the case, unless he works for Injen, he needs to post what he pulled......
He only posted up his baseline. His post said he was gonna do the after install pulls on Thursday, right? He said that gave him the chance to go back to premium gas and get closer ambient temps. Give the guy till tomorrow night.
To the OP (if he even sees this
) Was that the best, worst, or average baseline?
I'd spend the time painting that washer bottle if I were gonna open up the grille.
