Thanks for the pic Razzy....looks a lot like the AEM intake. Could you post another picture of the filter element. Thanks.

Speed...I reformatted Razzy's pic....add this to the first page.

kartweb if you see him again let him know mazda is thinking about fans as well and hasnt settled on a final configuration yet

Anyone think there's a difference in performance between the aem and the mazdaspeed? For the 75 dollar difference I think it's worth considering..

it is basically the AEM.
Ill go get a picture of the front end.

In your decision between Mazdaspeed and AEM, think about the year warranty that comes with the Mazdaspeed.

i was told by one of my contacts that it is aem building them for mazdaspeed

Well, i'm having trouble deciding between the RB w duct, or the AEM. I'm gonna be honest, whichever produces more power is the one i'm getting. I could be saving a little money, unless someone knows a site where i can get the RB set a good idea. Anyone wanna help? Seems as though this thread died off 7-31-06, now there's a new concern, hah. In which, i'm only asking for advice/help.

I would estimate that your going to see the same numbers from AEM and from the RB w/air duct. The AEM is more susceptible to the elements, given the filter is sitting low in the front bumper. You should keep your eyes on the For Sale section, as I expect there to be a lot of used intakes available once people start picking up the RP supercharger.

added, thanks Kwescott!

wow, posted that on 7/30.....:)

.......... I am a little slow ok?

:)

you should have reminded me. ;)

hey this might be a stupid question, but why are some intakes only 6speed specified?

only tested/dyno'd, designed for MT's.....Racing Beat for one said that their design will work for AT, but they wouldn't be able to post dyno results.....so, any intake will work.

i was thinking about getting rid of my simota intake and getting either

RB revi with duct, AEM(design looks a little cheap for me, never liked their intakes), or K&N type 2.

Personal opinion from anyone who has experience with any of these intakes, which would you suggest? Most hp gains if any, and which would have better resale value in the future? Basically looking for the best buy

.

thanks for replying so fast :)

not the highest peak hp but best over all gain. plus probably has the best resale value

rotary god approved

if the god says so, then it must be true. Thanks for the help :)

no prob, its late and im bored as hell.

i hear a lot of good things about the rb intake setup, i might just switch over

I've seen all three, had experience in installing the K/N and Revi w/duct. AEM and K/N both sound very aggressive, the RB is very low tone, noticeable over stock, yes. K/N would be the value option. We bought a K/N ver 2 off a forum member for one of our 8's, and I have the RB w/duct on mine. The RB looks stock, so I'm not worried about passing the visual portion of a smog inspection test...where as with the K/N, I know I will have to swap the stock intake back on before any emissions tests. I would assume that the RB intake duct would be beneficial if going with the K/N or RB...no need for one with the AEM since it is already picking up cold air given the location of the filter. The AEM design is the same used for the mazdaspeed intake...so it can't necessarily be bad...?

So conclusions....if I was going for sound and price, I would buy the K/N...and add the RB air duct. If I wanted stock looks, with a more subtle sound, I would go with the RB w/duct. Depends on what sound you want really (as well as if your interested in having to switch the stock intake back on for emissions testing)...performance is going to be about the same.

I had a question regarding the install of the RB Revi and Air duct.

I know that the stock air box has to be taken off, my concern is where did you fasten the wires and the round thing (sorry dont know what it is) that are secured to the back of the stock air box? Also do you have to also remove the plastic tray that is underneath the stock air box? When i installed my Agency Pulley I noticed that there is a small line that is attached to the tray, a metal piping that is secured to the tray and rubber hoses attached to it. If removal of the tray is required where should it be secured to.

Thanks in advance.

the RB kit comes with very clear and comprehensive instructions. Yes, you will be removing the tray, as the new RB intake attaches in the same location. All unusued wires (mainly the green V-fad wire) are ziptied, and suggestions for where to tie these is in the directions as well.

I, too, am in the market for an intake. Haven't heard much about SR Motorsports intake- it looks pretty nice, or that IRC intake they offer as well. So far I'm leaning to RB w/duct, but I'm a fan of the "tuner" look I guess you could say, so that's the only reason it doesn't appeal to me. I'm thinking SR or AEM.....

Dave

saw the SR motorsports unit...old technology. It was one of the first intakes out there for the 8, along with K/N first version intake. It was loud. Didn't think they made it anymore.

Well I justed ordered my Umnitza carbon fiber box intake today. Only $216 shipped priority. They were outta stock so I emailed them asking when then get back in stock, super-fast email responce (on a Sunday even!), said they would get 'em back on Monday.
I was mainly sold when I heard a few sound clips and saw some pics. I know there isn't much HP (if any real power) to be gained, just a smoothed powerband, so I no longer based my decision on HP gains but rather sound and look, and the Umnitza fits those requirements perfectly for me.
But I deff think this thread should be stickied!! A great resource.

Has anyone ever had a mazda dealership refuse to work on your car with a mazdaspeed intake? Or claim that this voided your warranty? I have read all the posts about the act passed saying they have to prove the part caused the issue, but I don't have time and don't want to deal with that kinda crap. My local Mazda dealer (which is not a mazdaspeed dealer) claimed that the intake would void my warranty on my engine. There is another dealer about 2 hrs away that is a MS dealer. I may check with them.

I just want to know if anyone has experienced issues and what happened? I don't want to end up having to pay for a new engine out of pocket.

I am considering some aftermarket mods, and trying to find the best bang for my buck. Since the MS intake claims hp gains, and so does Greddy SP2 exhaust, I am leaning in that direction.

anyone got any input on the HKS suction - its exspensive is it worth the price

$ for hp I would say it's not worth it. Others will tell you it is.

Rx8 has very high underhood temps. Even with the car moving I dont see how any cooler air would get to any intake that isn't plumed to the outside like factory.

Had a friend who had the K/N intake and was getting engine oil on it....his engine was going bad. He went into the dealer and the dealer claimed it was the intake. So, we put the stock intake back on, it had the same problem and the dealer did the replacement.

Just keep your stock parts in case something severe happens. Otherwise, the dealer is not going to give you any cra* for normal service work and you can keep the aftermarket intake on.

I would agree with this....so, whichever unit you get, consider adding the RB Air Duct to it. Another option to consider is the throttle body mod...for those of you in the warmer/non-ice regions.

I talked to the closest MS dealer to me, and he stated that no MS parts void the warranty on my 8 as long as it is installed by a MS dealer. I will most likely go ahead and get MS CAI. Thanks for your help.

Has anyone bought the revi from www.good-win-racing.com, its only $299 for the Revi and $119 for the duct

um okay so what really is the point of an intake if it provides virtually no additional Hp? What I see in a lot of cases, less HP.
I want an intake that doesn't sound like a rice rocket or just a rocket (K&N, HKS). I want a deeper tone than stock and what I heard from Revi it really isn't much difference at all from the stock intake. I like the looks of Umnitza but you pay for what you get and i really haven't heard anything negative about that intake yet.
am I better off just keeping the stock one? -sigh-

Ditto that. I'm with you.

I have the Umnitza intake and I like it. Better than a K&N (don't ask how I know ;) ) I would say no or insignificant loose in RWHP. Plus is sounds mean and looks like sex.

HOWEVER, all that being said, I am still considering getting the RB REVi or the AEM cai. Mainly just to see if I gain any rwhp.

Also, it's BS that intakes don't add ANY horsepower. They do. Some people just started saying it and now everyone parrots it as a generlization for all intakes. It's true we don't get as much bolt-on power as say an Evo or 350Z but you will see a RWHP increase with a qualitly intake such as the REVi or AEM.

well yeah, it is true. you will get SOME increase. I have a K&N (and I love it) but I dont go telling everyone that it made a differance. because the differance is not worth bragging about.

When someone ask "so does the intake do anything" I usually reply "it sounds cool" :)

with all my mods I was able to pull 201 on the dyno. so yeah, it must be doing something. (and I dont even have an exhaust. thats just the intake, pulleys, and flywheel) but again, its nothing to wright home about.

with that said, if your looking for more power.... something your gona actually feel, there is really no mod for the RX-8 that is going to put a smile on our face from ear to ear unless you go boosted. everything else is minute.

anyone have a soundclip of aem?

Bad thing about K&N is that, I have to wash the filter more often. Every 5 K miles for me. the design attract dirt really .... good, well thats a good thing actually.

reall, i Never clean mine. I have cleaned it once in the 2 1/2 years its been on the car...................


then again I only have 18,000 miles on teh car and its an 04. maybe that would explain the lack of cleaning.... never mind. :)

Blitz Sonic w/heat shield

Cant find any US sites with it at the mo - but I'm sure somebody somewhere is sells it.

Its what I'm using currently and me love it loooong time ;)

http://www.blitz-uk.co.uk/Product-17.aspx

The Odula is about $190 dollars (converted from YEN and JDM price) this is without shipping. Japanparts would be more specific about total cost. It fits with the stock box.

Sure wish somebody would make a "knock off" of this and make the inlet a bit bigger. Overall, I like it and it works well.

it's probably more restricted than you think ...

^^^ I finnally just cleaned it maybe 3,000 miles ago. it was starting to get a little oooogly.

The Aem Cai also provides much cooler intake temps vs stock...With the stock intake I was seeing intake temps anywhere from 10-30 degrees above the ambient temp outside while moving, now that I have the AEM cai, my intake temps hover no more than 15 degrees above ambient while moving.

When on highway I have yet to see it top 5 degrees past ambient temp :)

anybody know if that blitz filter can replace the k&n design?
the k&n has a huge diameter... not sure what it is...

Which intake sounds better the Weapon-R Secret Weapon Intake or the Mazdaspeed Intake? Which one gains the most power? Thanks.

dude, did you not bother reading any of the 5 damn pages on this thread? :spank:

If he was a real fanatic, he would have read it.

and he'd never consider Weapon-R crap for his car.
