I think I'm leaning towards the Injen over the AEM. Mostly because of the open filter element for the sound and also for the availability of the Cobb map (as opposed to the K&N).

I'm surprised nobody has tried the K&N Typhoon yet? Would any of the Cobb maps work with the K&N?

 

I have the K&N! For the price you cant beat it. It comes with the uicp if you get the combo and you can hear the bov and turbo if thats what your looking for. Fit and finish is great and I like the heat shield it comes with. Plus the wrinkle red matches with the stock engine cover!

 

Any CELs? Also, any stumbling with the AC? Any other mods you have with it?

 

No cel's or any other problems. I also have 3"catback/testpipe, forge wga, mbc and tune.

 

Hey all,

I posted something similar to this in another thread, but it got lost amongst the argument about whether the AEM raised boost and cheated the test - which isnt what im trying to establish... to maybe this is a more apporpriate place to ask this question:

What i REALLY want to know is, if I was to use the AEM on a tuned car (one where the boost is seperately controlled so that aspect of the AEM becomes irrelevant), does the AEM remove a bottle neck over and above the stock airbox with e.g WORKS or even an HKS panel filter?

I'm trying to avoid using a typical induction kit with a sheild, as i personally dislike the noise produced, AND i feel the car loses bottom end torque (this may be phycological due to the increased noise at various throttle positions but i always find this sense of relief when i admit defeat and put the airbox back on and enjoy driving the car much more in "day to day driving" mode)

I personally see the AEM might actually solve my problems - but i'm not sure how I can establish if its general design would allow more air to be sucked through, (assuming other limitations were removed) than the stock box/filter design - or if indeed there is still a restriction compared to say an Injen which probably has a larger filter surface area.. for example, does the snorkel pose any real life bottle necks on the air intake when you get to high tunes, so that any air box attached to it will always be restricted? Or is it more than capable of letting through enough air to allow pretty high figures to be reached?

All thoughts greatfully recieved!!

 

Bump for a response from somebody who can answer this question above.
Does the AEM CAI give more power than a Works or HKS filter using the stock box ?

 

I would like to know if the AEM intake produces more than the stock air box with a Works (or K&N, Perrin, etc.) and a Perrin Turbo Inlet Hose assuming boost is the same and both setups are either tuned or untuned.

 

Is it dry or wet type?
And what about that "myth" concerning wet type and MAF?

 

No answer...
What I know from K&N rep, all their filters are wet.

I have to make a decision in a day or two but without your help it seems difficult...

I do not care about the sound - I just want to let the turbo breath freely - what would you recommend?
What about those cone filters without any covers/shields, taking the hot air from the engine bay - is it a big loss over those using system like i.e. K&N does?

 

Another issue that needs to be addressed is the problem when the radiator fans kick on. Apparently the open style short ram intakes cause the motor to hesitate once the fans kick on.

 

"To hesitate" to...?

 

I started this thread and after hearing everyones feedback I got the K&N. In fact I literally just got back from test driving it after the install.

My feedback is:
It's an oiled filter, but I don't beleive the myth about the oiled vs dry filter. K&N has be making them for years and they even have a guarantee with the product that if a service provider fails to warranty your car for any issues because of the K&N, they will take care of the problem. I'm sure they wouldn't do that if oiled filters were a known problem. Plus how many vehicles have MAFs and oiled filters...the Evo isn't special because of that.

Install was not too bad, it was harder to take out the stock stuff than to put it on. One thing that I liked was that their air shield acts like more of a box than a shield, I actually had to make sure that the hood would close. This should get rid of the stumbling that occurs when the AC is on and the car is stopped or going slow. Plus I like how it has the "ram air" effect by utilizing the stock air inlet.

Driving wise, the turbo spool and the BOV sound is addicting. You feel the HP gains more in the top end and the revs definitely seem to go quicker. The car also sounds (inside the cabin at least) a little quieter at WOT, but cleaner and deeper. One thing I also noticed was that the car seemed to idle better than stock. One thing I never liked was when you had to go real slow, the car seemed like you had to ride the clutch or it would bog, for some reason it feels much smoother when doing something simple like backing up. I have no reports on gas mileage or anything yet, but I suppose it will be better.

 

Thanks for your feedback!

IF the K&N was with polished/brushed lines I would have bought it straight away.
I just can't stand that wrinkle red color.
I have to admit that money-wise it is best option on the market!

Last but not least (if not best part) is that it uses stock air inlet. That, I believe, gives much lower temperature of the air supplied to the turbo which can not be underestimated.
However I would like someone to clarify how much better that design is vs just open cone not using the factory cold air inlet.

 

What do you guys think of ETS intake compared to the AEM? Most people have AEM, but I hear that ETS makes good power. Which one makes more? and more reliable?

 

An intake by itself should only make it easy for air to flow. If its making power, its most likely doing so by screwing with the MAF sensor readings. The ETS intake reuses the MAF housing and does not play this trick. Hence, tuning can be done more predictably.
