yup RAY has tried them on his old SIR...

im not really into this but what would you recommend me to use given the ff:

Vehicle: 2004 Ford Escape 2.3L

Priority:

1) Minimal sound. At least the filter should sound as noisy as the stock ones. Im into car audio and any noise is a NO NO for me

2) Horsepower given by the filter

3) Price (but its ok for me to shell out money as long as the filter wouldnt be noisy)

Thanks guys!

Oooohhh... this would be hard. I've never really encountered a filter that would give that silent DB you're asking.

Well.... at least an Open-type one

Maybe a drop-in K&N filter would be ok If there is for your car

Dont worry too much about the noise.

Not that much naman, so get an open type already.

If not, get a panel filetr which will fit your stock airbox, also it is easier to find for your car.

open type? hindi ba maingay yung mga open type? kasi some people replace their filters for performance AND for the sound it produces.

ako kasi im after the performance lang, yung sound ayoko.

is there a muffler/headers system din pala that will give me more performance for my car without adding any noise? or lahat maingay?

Stay stock if the added noise will "diminish" your audio experience.

k&n will have an open and a drop-in for you application...

if u usually don't hear the environment outside, then the sound emitted by the open intake shouldn't bother you much...

How much is the apex-i selling there now?

We got the HKS inputs from a local engine tuner from his dyno tests.  I use HKS in my race car but I use K&N for my street car.  Race car, we rebuild engine a lot and HKS gives maximum power.  K&N has better filtration i think and lasts longer.

wow! i created this thread on: April 25, 2005, 09:27:32 pm - almost 3 years ago.

sirs, good day to all, i have a k&n cone filter on my civic esi, it really sounds good when i accelerate, and i really like it,  but my problem is its hisssing... to much at idle, is this normal? and with the hot weather today, is it good to put my orig. airbox back?

normal yun hiss. if you stock airbox get its air from outside.. then ya, the intake air temp will be lower than the open k&n filter. otherwise, pareho lang yun.

Hiss sound is normal if you're using open type filters. I just noticed on my filter now the whistling sound aside from the hissing sound. I haven't experienced the whistling sound before on my other filters. Though i like the sound of it now.

Honestly to make power, its not the filter itself that robs you the HP.  Its the restrictive piping that came from the factory.  Keep in mind that the stock intake pipes were made with baffles to keep the intake noise down.  SRs are notorious for this crap.  The stock rubber hose sucks hardcore.  Change it to a custom metal pipe and you will see an instant difference.

Uh, where do you get your facts?  If the air filter doesn't "rob you (of) HP", why does removing the filter of any intake give you more power?

Are you talking about the Civic SIR?  I was on a dyno with a bone stock SIR...I removed the front airbox (the one that holds the filter), not the "stock rubber hose", and got an instant 15hp!  The stock rubber hose is actually very efficiently designed cuz it tapers down gradually in diameter, increasing velocity as it enters the TB.  There are no baffles inside aside from a hole that leads to an external small plastic "resonant" tube that I removed and plugged up. 

If you use a large diameter intake pipe, you decrease intake charge velocity and lose low-end and mid-range torque but gain overall in top-end power.  Again, these are dyno results.  This is not good for street economy. 

Furthermore, metal pipes like some custom intakes are made out of, especially the cheaper ones, absorb a lot of heat.  From my programable engine management system, we can datalog the IAT sensor, or the intake air temp.  For every increase in 10 degrees F of intake air temp, you will lose quite a bit of power, something like 3%.  Obviously, changing your stock intake to metal pipes will heat up the intake air after sitting for awhile.  At the same time, exposing the intake to the hot engine compartment temps will decrease power.

Non-metal intake pipes are better but pick those that increase the intake velocity and supply a large enough volume of air.
