Yup, that was what I was holding out for, but the tuner suggest I switch it out because the MAFS is always trying to adjust the ECU with AEM's setup. He suggested gen 3s if I felt the need to have an aftermarket CAI. I think it the whole law of diminishing returns as you add mods related airflow should equal thing out since I have ART pipes and a better flowing CBE. The whp loss should be no more than 5. It's more about peace of mind at this point for me. I don't track, but I want my car to perform the way it looks!!!

I think the G3'a are also the best because intakes like the AEMs and Takedas have oversized piping that gets smaller at the MAFs... Which creates choppy air, not smooth airflow

I have no issues with my AEM's. I think the ETI module works. There was no discernible difference between my untuned and tuned numbers. Car got tuned, dyno'd it in similar conditions as my original run and it was the same result. AFR's were within .3 of each other, 9 months apart, and at a different elevation (still a dynojet). I made decent gains on a modified car, but it was including pulleys. 16whp combined gains, I would guesstimate 8-10whp above 6500rpm came from the intakes. The intakes don't neck down at the MAF to "trick" the MAF readings, it stays the same diameter. I don't feel the intake location is a problem. It does not receive direct airflow, but it is not a sealed space, and I have not sucked up any water, even after washes or torrential rains. They come in polished or powder coated gunmetal for the same price and can usually be found for at least $100 cheaper than the G3's.
In my opinion, there is enough evidence to say that the difference after tuning between CAI's is minimal. Lastly, because the ETI modules are still functioning after tuning, the ECU is not going to try and revert what tuning changes were made to the AFR's. I don't know how much of an issue, if at all, but some cars do this on their own. |

I guess if it is about the biggest and best numbers, then be prepared to spend some time and money getting to know your Z...she like a woman. No offense ladies! |

the only thing i don't like about stillens, is they are kinda ugly imo. why do they have a random coupler in the middle of the intake?? BUT, u can't argue with the great track record that intake has had. if i had to get an intake right now, it would be akumas. simply the sharpest looking intake available at the moment. they will all perform within 3-4 hp of each other, so differences are negligable. just boils down to opinion. |
Also I live at 7000 feet above sea level. I know on stock Toyotas the mafs read low and are fuel trims arent normal as a result of the elevation. I know my power here is lower and that gains fron anything will not be as great. Im jusy wondering if these systems will function properly at my elevation. Thanks

I'll have something neat for you guys in the next week or so :)
A few members already got the inside scoop but I don't want to leak all the info just yet! Very small teaser: Our intakes 1) work on the stock tune via a tuning insert by the MAF, 2) with the tuning insert removed you run a full 2.75" piping, this requires a tune or recalibration of the MAF, 3) if you decide to go with our TT kit in the future, the intakes work in conjunction with our IC piping! so you won't have to try to get rid of your intakes or sell them! |
!Come check out the Akuma Spec Rev3 Intake!
-The Rev 3's are made from 6061 aluminum and include nomex couplers, K&N Oiled Filters and include all necessary hardware. -They are made for ease of installation and removing with as little work as possible -K&N Filters with angled inlets for optimal fitment -12-14whp increase can be expected using just the intakes! -More can be expected with proper cat back exhausts! -20whp increase with an invidia catback and the AKUMA Rev 3 intakes! ***These intakes require tuning but for anyone with an Accessport or an Up-Rev we can provide the proper info to make the changes yourself*** We have multiple threads with plenty of info, commentary, and dyno sheet on these intakes in the link below -http://www.the370z.com/group-buys/58954-akuma-motorports-rev3-intakes.html -http://www.the370z.com/intake-exhaust/55275-akuma-motorports-370z-intake-post1771764.html#post1771764 http://i576.photobucket.com/albums/s...s/DSC_0148.jpg Brushed Aluminum Installed http://i576.photobucket.com/albums/s...s/DSC_0164.jpg |
SS, did you by any chance compare IAT readings via an OBDII reader before and after the AEM install?
|
I haven't had any hestiation with my aem but has been causing random misfire code and cold weather seems to trigger it more often.
The electronics on it probably are bull so I plan on eventually having it bypassed. But it same diameter throughout so haven't done it , plus I may just wait until tune. |

it's summer here in Australia and yesterday the car drove so badly it was not possible to overtake. i'm getting massive heatsoak issues - 50-60*C while rolling at 70kmh is ridiculous.
Thing is, the right hand side is the side the ECU reads IAT from and this happens to be the side with the power steering cooler lines which are blazing hot. I wrapped them with exhaust wrap yesterday and put some foil around the intake pipe so we'll see how it goes. Thanks for you input though. It's really disappointing. I also tested to ensure the ETI box is not fudging the signal or sending a signal of ita own. I pointed a hairdryer at the ETI box and it did not affect the IAT. It is definitely reading from the MAF sensor |
