i'm looking to put a cold air intake system on my 05 rx8, but i can't decide which one. a friend of mine has used k&n on multiple cars and says they work great (he also said that aem doesn't work as well in ohio weather?). but i looked at one test result online and it said that aem gives more horsepower. disregarding price, which do you think is better and why?

edit: my apologies for not using the search bar. there might be a thread out there like this already

 

a **** tonne of threads on the topic

Here is one of my favorites

https://www.rx8club.com/canada-forum-35/any-you-aem-cai-209356/

And being from Ontario the weather is likely to be similar

BTW
Don't you eve dare buy a K&N intake for the Rx8 ... both versions are crap. You're better off with a K&N drop in panel filter

 

AEM, problem solved.

 

Racing Beat for the win!

 

I have a k&n drop in and it work fine. I'll say k&n for sure.

 

aem is a true cold air intake.

 

mazda speed, pay more

 

with all due respect i need some reasons for either one. just a heads up i live in ohio and i will be driving it in snowy weather. if this somehow will hurt either intake, then let me know.

 

the reasons can be found with a search

 

thanks. i actually found my reason to get the mazdaspeed cai, so i can keep the engine under warranty lol

 

unless the CAI was the cause of engine failure then you would still be covered if you have a non mazda speed part, but yes its worth going for the Mazdas peed CAI over the AEM since they are both the same and you get warranty.. with Mazda.I have the Speed CAI, on very rainy days I had water being sucked in, but kept it under 5000rpm and i was fine, drive through car wash, I just get in and shut off my motor and let my car get washed and i turn it back on again. Good luck with your purchase

 

would there be any problems if i just washed the car myself? and what about winters

 

Why didn't you read this ...

Would have been answered if you read the above thread.

 

lol, unless your buddy is in the car reving the engine and you are directly spraying a hose in to the intake and your other buddy is washing your car....... then yes.

and my car never sees the winters. So I could not say.

 

Freezing rain can cause a serious problem with the AEM/MS CAI intake design

 

Whatever ..... .....
Over the stock intake ..?????????????????

Prove it
You can't

Such a silly comment .... why would you do it?

 

yeah, I never had that issue, Come november the car is stored, but I see where you're coming from.

 

Between the aem and k&n .. THe aem is a true cold air intake and the K&N is not.


But yes the Stock intake design is a cold air intake as well. I didnt say it wasnt

 

Ahhhh yes ... I mis-read it ..
My mistake

 

I have the k & N its a bit loud thats all you really get...

 

aem or racing beat, thats it, k&n sucks in hot air, and since most people over oil their k&n fitlers, resulting in a dirty maf.

i had these intakes in this order on my rx8

!) k&n drop in stock airbox without the walls
2) k&n version 2 super loud
3) i had the racing beat intake one of my favorites.
4) i had the aem a true cold air intake, it was a lil loud too but not obnoxious.

so yeah either rb or aem is the way to go

 

i love my kn intake its nice and loud
no problems with it dont know why you wouldnt want it

 

build your own, and put an ice pack in it,

 

You have a sense of humor. Anyway, i need to build my own too...lol

 

i'm in the military man, if i have no sense of humor i'm dead lol
