can u guys tell me some good option for air intake??
thks ^^

 

For you stock is about as good as it gets.
https://www.rx8club.com/series-i-aftermarket-performance-modifications-23/stock-intake-vs-racing-beat-109949/ is a good place to start reading, you can do a search for Intakes. But the bottom line is even on 6-speeds Intakes provide little gain and those gains are in the upper RPM range. You can't get above 7,500 so expect an intake to only provide noise on your AT.

 

I'm running the racing beat w/ram air. It seems like most popular but some others are AEM and K&N and a couple of others. I'm very happy with the racing beat. You'll probably get flamed for not searching so be prepared.

 

ya~ i saw revi intake by racing beat,, wat is RAM air? wat do u thing about HKS racing suction??

 

is there any aftermarket product who can give unique and loud sounds from the intake?

the stock airbox with the RB air dam is the best your gonna get. . .
but if you paint the air box RED then your lookin at 10-14+ hp. . . .

 

how about blue?

 

the ram air replaces the stock tube and gives more air flow in from the front of the car. It takes up the entire lower portion of the grill. I think it gives you the best fresh and cool air but like other people have said you want get alot of extra power out of it. I like the sound of the R/B intake it's more throaty but not stupid loud, and you only really hear it when you get on it.

 

i don't know much about the HKS wish I could help.
