Hello guys... i'm a newbie here.... i'm looking for changing my intake system. i did a few research already... but still it doesn't clearify which one is better...air box or open port intake.... and which one it the best intake systems in the terms of power gained and sound produced... i hope anyone can help me with this....

 

IMO they are all worthless as far as HP is concerned. Many of them cause more problems than not. I would save all you money until your warranty is up then get the turbo/interceptor package.

Most people will stear you towards the REVI, AEM, and MS intakes. They all cost entirely too much for what you get and will give you 1 hp if your lucky.

 

That's not true. Several of them have shown several hp gain, not 1 hp. The AEm & Racing Beat have both shown dynoed results in the 8-9 hp range. Even the new Short Ram unit from K&N gave a 4 hp gain (see Import Tuner magazine article), and the REVi (without Ram Air Duct) similar gains in the most recent magazine. Polak did a writeup on the Racing Beat unit for RX Tuner & got measuable results in te 10 hp range. Price vs. performance is a personal decision, but hp gain is real.

In general the units out there are :

HKS
Racing Beat
AEM
K&N
(upcoming Mazdaspeed)

Depends if you want a short ram (inside the engine bay) get less hp, but installation is a bit easier, or cold air intake (varying definitions).

 

I went with the Simota Intake CF SR Intake. This is an intake that you need to do research on before buying it. There are a few threads that are 23+ pages and you should read em all. You can buy the intake from umnitza.com and it has a nice sound to it. Search my posts where I posted a video of mine.
