thoughts on aem eti vs stillen gen3

The takedas were designed specifically so that no body work needs to be done. Well, from what I've read anyway since I don't have them. I'm just waiting to see if one of these pops up for sale, I'm in no hurry for them.

No cutting, then I'd like to see a pic of the silicone section that goes through the opening if it flexes at all to accommodate the small gap...

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

SS_Firehawk · 01-05-2013, 08:35 AM

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.

Hi SS, I have been waiting for you to weigh in as you are a fan of AEM. This really was the point I wanted to make. Each Z has its own personality and from everything I have read pretty much shows that if you get a tune the gains with most CAI are on the upper end of the RPM range and are within a few hp of each other.

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 intakes and pulley's were by far best bang for buck improvement I made to the car. Unfortunately, I have to remove both for my twin supercharger upgrade... I have a lot of info my my sig link about it as well. Indeed, these cars do have their own temperments. I'm happy mine worked as well as it did before I decided to do my new project. Nearly every mod I did was never considered the most popular option, some controversial, but my gains definitely show. I made about 50whp over my baseline, I can't complain. Researching is really key, do your homework before opening the wallet. Everyone wants to vouch for a product that works great for them. Cheers to that, spread the word on products that perform.

I have the same without tune and same results. I am completely happy with aem. I only had one instance of moisture right after I installed the. Since then nothing. I didn't get a CEL until I put my catback with test pipes. Even then it was an air fuel mix error and it actually regulated the idle so I didn't clear it the second time it came on. I would log it to see but the CEL isn't always a bad thing. I think it's smart to include a self regulating module that adjusts on its own and helps the car run right. That's why I went wit aem...that and powder coat out of the box.

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

Sales@AAMComp · 01-05-2013, 02:58 PM

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!

Kevin@AkumaMS · 01-08-2013, 10:29 AM

!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

SS, did you by any chance compare IAT readings via an OBDII reader before and after the AEM install?

I didn't get a before, but IAT's were within 10 degrees of ambient when in motion.

juld0zer · 01-15-2014, 04:40 PM

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

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.

SS_Firehawk · 01-15-2014, 05:20 PM

Oil cooler and radiator upgrade would make a big diff. Both are undersized for the car.
