I've had multiple AEM intakes in the last 10 years I've been in the import scene. I've been proven time after time that the bypass valves in fact DO take away the gains. On the aftermarket applications, AEM chooses the bypass valves as an option. I've always stayed away from it and I've been to multiple dyno day events, seen third party dyno charts, etc showing the power loss as a result of installing the bypass valve. If the bypass valve had absolutely no drawbacks, why do you think AEM doesn't have it fixed welded to all their applications? There is a reason for that and they know it. If you think about the concept of a bypass valve, it makes absolute sense that it takes away some power.

Exactly. They showed that it works. I'm sure it does work. But they chose not to post the dyno numbers with the bypass valve in tact in comparison to without. The bypass valves do not stay completely shut at all times. I've witnessed during dyno days where the valve partially opens due to the suction that's created during WOT. Pulls in hot air and ruins the dyno numbers. Makes sense and that's what I've first handedly witnessed.

i know they work, but they're just horrible to have unless you feel like you need them. They're like $50 a piece and they break so easy. I always had so much play in my piping with them on. Plus the foam sleave always seemed to wear away fast. IMO they're junk

Yup. I don't know of anyone that actually had a positive thing to say about them. They are useless unless the entire filter is completely submerged underwater. At that point, you might as well ruin the car anyway because it literally takes driving through a 2 feet lake to completely submerge the filters and you do not deserve to own this car or any car for that matter. I've seen guys accidentally drive through >1 foot puddles countless times with no adverse effects. Marketing gimmick and a way to save their arse from lawsuits if you ask me.

You need to read a little more before you attempt to be an authority on the subject. The bypass valve does NOT "constantly pull in hot air." It is called a valve because there are rubber flaps that stay closed during normal operation. The foam filter pulls absolutely no air into the intake unless the bottom filter is submerged. Like I said before, read the article and understand how it works.

in response to your it stays shut until blah blah blah the air is pulled by a vacuum in from the intake it enters from the path of least resistance like said. those damn valves are always slightly open thanks to them even being there so there is always a leak of hot air into the system they just don't open all the way until there is a downstream restriction (water or a dirty filter). not to mention that the valve itself causes turbulence in the pipe and hurts performance simply by being there. which is why a lot of people with aem intakes throw that crap out and install a silicone coupler then it's a great intake.

I had the AEM intake on my Titan and it was a great intake, didn't have any of the bypass filter nonsense...

Thank you. Only people with extensive AEM experience know this.

Schrute, holy hell it looks like you had some fun in that! Good stuff.

btw, you quoted the wrong person.

Any word when the intakes hit the street? I had AEM in my Tiburon before I traded it in and I love their product.

Bump..
Any updates

I'm not too familiar with the 370Z as I don't own one, yet. But coming from the Acura side of the automotive industry, I know that AEM did have a small foul up with the brackets breaking off the tubing all together. Don't get me wrong, they sure as he** make great products, and I'll be in to get one as soon as I pick up my Z! I just wanted to give Z owners a heads up. The culprit was the p2r TB spacer that many of us were running. Does anyone even make a TB spacer for the 370 yet? Not that it would yield any significant bump in hp/tq, just curious...

:tiphat:

any updates? i've sent AEM several emails and they won't respond.

It has been on hole for a couple more weeks again. I will notify you guys when I hear from them again

....

Aparently mine is getting shipped to me, I will let you know how that goes

sure is taking a long time, i'm hoping they are worth the wait.

Not really sure what all the waiting is for... it's going to yield close to the same exact gains as say a Stillen long tube set up. I mean, at the end of the day they are both aluminum tubes with filters at the end.

The AEM should be the dry-flow filter, the k&n look a like that stillen uses may be oiled, i am not sure, and if they are when you go to clean the oiled filter there is always a risk of over oiling it and fouling you maf. With the dry-flow that aem has you just soak it in solution and water and agitate them and then let them dry out.

I don't think the intakes really do much, but that is true at least for my car a 08 350z. I dunno 500 bucks or so for these suckers just don't seem worth it to me.

the stillen is ugly, AEM will have a more finished look.

There are 2 things going on with the intake.

One is how much power is gain by efficiency. A less restrictive open element filter, smoother intake piping/bends.

The other is how the design of the intake alters the air fuel ratio. The diameter/length of the piping and placement of the air meter play a role in the A/F. Some companies go with the design that leans the A/F. Lean means more power.

It can be deceptive. What HP you think you got on the dyno may not be from effieciency or a small drop in air temp. It could be how they tuned the intake to lean your A/F and make power that way. It's power you could have gotten with a tune and drop ins. I'll likely get an intake at some point but those are the theories that make the choice difficult in terms of value. By the way this comment is not just directed at the AEM intake, it applies to them all.

they do make a difference in the VHR .

No matter how much they wish for it the 350Z is not the same as the 370Z. What's the deal with all these threads lately saying how easy a certain job was or how there was no gain shown with a certain part only to find out the person has a 350?

Looks like it will be released very soon. Like the Injen, a windshield washer reservoir is also included. Finishes look to be either polished or a gunmetallic finish. The only difference between this and any other intake we have on the market currently is this "ETI" technology. Supposedly it will alter MAF readings to trick the ECU into reading that air flow is normal. This might be a good alternative for those who want a CAI but already have full bolt-ons. Usually a CAI install will result in lean conditions without a tune for those who have full bolt-ons already.

I'm waiting to see how this will play out with those people planning on tuning their cars.

It also seems that retail will be right around what Injen/Stillen CAI are currently running for...no surprise there.

damn! those MAF sensors are gonna be down there hu? haven't really seen the Injen but i know Stillen's are close to stock position....this AEM one looks diff.


also i'm digging how its all a once piece.

Nice but only 9 hp gain?

Nice!!!!!!!!!!!

it prob only makes 9hp because it doesnt run lean

:tup:

hmm so no bypass valve like the older pics?

Bypass valve is normally a user-installed option on most AEM intakes.

But where would you put it on these, with them being a single tube on each side?

I might jump on this since it doesn't require a tune and won't cause the engine to run lean. If anything I'm going to run rich after the LTH install. I prefer holding off on a tune until UpRev or Cobb can make some series jumps in tuning capability instead of being limited to correcting A/F ratios

Here's what the charcoal finish looks like in case anyone is interested:

Pretty good match with the PG paint

anyone know when they come out?

A few shops I've talked to are taking preorders. Same thing we've been hearing for the past few months I guess: soon?

for people only getting the intake and no other bolt ons, would it be a better idea to go with stillen/injen since you won't be running too lean just with an intake anyway?

Those look pretty nice. I wonder why they use such small filters though. Let those things breathe! or do they just not fit?

These ain't for a 350... :)
