All this info is available with the search feature. You should try it. There's alot of good info available immediatly.

I'm using K&N OEM style air filter in my car. I use it mainly because it is reusable.

Here's a tip for doing a CAI (cold air intake) for your stock air box. Pop the hood and look for a piece of rubber that attaches on the hood (behind the grill). This piece of rubber acts as a barrier preventing bugs and some other dirty stuff entering into the intake. If you look closely, when you close the hood, this piece of rubber blocks the intake scoop. My suggestion is to get rid of this piece of rubber to get more air from the outside. When there's more air being drawn from the outside, the air box stays colder. I do feel the car gains a bit pick up especially on higher RPM.

The only down side is the air filter gets dirty a bit quicker. So, I highly recommend using a resuable air filter for this mod.

 

heh i'm aware how to use search it's just i rather to open my own tread due to there is some question that they didn't cover in other threads..

and i feel attention when i start my own

 

may I ask what's CAI (cold air intake) needed for?

same for better air flow? basically extending air filter?

 

alexus - Colder air - denser air - denser charge - more power. Very, very slight ram effect.

 

the whole post started as i wanted to change air filter.. now i'm thinkin.. i should probably go with whole intake.. and get that cold air box for intake.. or seperate so it will get cooler air..
