hopupracing.com look up the rx8 and they have the aem cold air intake system there and it claims like 15hp/12ftlbs of torque has anyone bought one of these? what are the pro's and con's...my bday is coming up so i want to get myself a nice present and i was looking at that, any input would be appreicated. would mazda null warranty cuz of that -.-? thx in advance

 

Pros - sound, slight increase in power, definitly colder air
cons - sound, light increase in power given cost, cleaning filter might get annoying
search - most people are going to tell you to do a search on this perhaps in the intakes, intakes, inteaks thread

 

I have the Mazdaspeed CAI which is essentially the same thing and I like it. It definitely gives the car a racier sound (IMHO) and it'll give you a bit more power which you can feel if you're really in tune with the car (no pun intended), but don't expect it to pin you back in your seat. Although, if that's what you're after, a CAI isn't the way to go no matter who makes it.

 

I have the AEM CAI, I love the sound but it didn't add much power to it (I wasn't expecting it to) It helps a little, but like the previous person said, you may not notice it unless you really know your car.

 

those claims are too high. maybe 3-5 hp

 

i was one of the 1st people to get the AEM on the boards. It sounds awesome , especially when driving under a tunnel sounds exotic kinda. Power wise you won't feel 3-5 HP. it's a good intake i would recommend it

 

Make your own for 1/3 the price like I did. That way you can spend the extra money on another overrated mod.

First version I made as a short ram:

Second and final version was a custom CAI:

I have been running my setup for months with no CEL.

 

The only thing I didn't like about the AEM was the WOT sound at low rpms. It drones loud enough to be embarasssing. After 5K though the intake sounds amazing.

 

Thats why I like my K&N more !

 

all aem's must do that because on my celica it was just plain annoying

 

K&N is that good? thats weird cuz when it first came out i heard people complaining about the loss of power -.- maybe they were talking about something else. but iono does CAI or any of that stuff null warranty cuz currently my car is kinda "sick" and i have 36k miles already so i might just wait a while if it nulls warranty and just drive the stock car cuz its more then enough to have fun with.

 

we are talking about the K&N typhoon ver.2. The first typhoon is the one that had the problems with not keeping a steady idle and stalling due to not flowing air over the MAF evenly (lack of using screens). The typhoon ver.2 fixed this problem with the new design of the intake filter and using a single screen.

 

hey can you write more about ur custom intake?....did u cut out the box?...did you write a DIY?.....more info please..how much u spent?

 

yeah is it true that it voids the engine warranty? installing a CAI

 

Yo I run the AEM; the visual when you pop the hood, and the sound is worth it. anything else like +3-5hp is a +.

 

If installed correctly, a cold air intake will not void your warranty. All it does is smooth out airflow compared to the stock intake box, so nothing is really altered.

IMHO the AEM is the best intake on the market. It has dyno proven horsepower gains (not anything you'll instantly feel, but you will gain around 5 horsepower) and it will lower your intake temps quite a bit. Its definitely the best looking intake, and sounds pretty similar to other intakes.

There really aren't any cons. I have yet to have any problems driving in the rain (if you're on stock springs the filter should be about 5 inches off the ground). I guess the install is a little harder compared to short-ram intakes but the lower intake temps will make it worth your time.

 

Dude, seriously. Get on that

 

If there is one advantage to using the AEM it's the fact that the intake piping is the same diameter and shape of the stock intake piping.

While there are those of you who have made your own CAI, it's not something I would advise. The Mass Airflow Sensor on the RX8 is very very sensitive where the slightest misposition or angle can cause unwanted effects in your fuel delivery. Also the overall diameter of the tube will impact the readings your MAF sees. Without the ability to calibrate your MAF you could actually be robbing yourself of power.

Kudos if you know what you're doing but otherwise I'd stick with the AEM. However, there's no definate data showing gains over the stock intake and in fact with a replacement drop in like a K&N or a Green filter there's no reason why the stock intake can't deliver the same Intake Air temperature that the AEM does.

The stock intake on the RX8 is well designed which is why replacement intakes do next to nothing except lighten your wallet. If you're dead set on getting one I would stick with the AEM.

 

BHR offers the AEM ikntake kit for $328, shipped, and for the month of April the price is WAY better than that.

 

Our engine bay is in dire need of some elbow room too though. For how small the Renesis is there are sure a lot of plastic bits cramping its style. That's the sole reason i'll probably end up with the AEM.

You're making my decisions difficult here CRH... I've already planned for a pricey April mod which is not an intake... must, not, give, in...

we'll see

 

Our car already has a cold air, drop a K&N filter in the box and you'll see the same results you would with a fancy aluminum tube that costs hundreds. Any modifications to my intake will require piggyback or stand alone tuning.

 

Yeah I kind of did the same thing. I took a cut off wheel on a grinder and cut off the tube comming from the air box. Then i went to NAPA and picked up a K&N filter for a Tahoe (so it was long) It sounds amazing, and i only spend $60 on it. I have pics if n e ones interested

 

Does anyone have a DIY installation link or video for the AEM Cold air unit?

 

When you buy the CAI it comes with a manual. You can also get it from AEM's site.

 

I'd say 3-5 very very max
