I installed my intake yesterday n i noticed that there is a noticeable air sucking sound while driving at around 3000-4000 rpm? is it normal or its a leak?

 

if it sounds like this, it's normal. Short ram intakes do make a distinctive sound.

it does sound like this but the air sucking sound is not loud enough to be heard when ur filming it, only the people in the car can hear it. let me know if u can hear a sucking sound on urs too?
ps. i didnt remove the snorkel from the stock intake coz it will bring cooler air into the area where the air filter is located, is this the reason??

 

I did the same thing with the snorkel and yes, I can hear a slight sucking sound. They pretty much all do this.

 

im about to take the SRI off of mine..i have the v1 intake..and it grows when i get to about 3.5k which is a little too much for me...specially when its making all that noise and going no where haha..

im gonna get the injen i heard it keeps down the noise but still gives it a good sound

 

its very true that after 3500rpm it really starts to sound loud but i can live with that lol

 

i have the injen CAI

and basically i can control weither it makes a sound or not by pressing the gas lightly or harder
if im light on the gas i can make almost no sound @ all
but when i gun it u can see a deep throaty sound

 

It's called a vacuum which is good when you have an aftermarket intake.
More sucking = better performance

 

i have the v1 and it does have the sucking sound. but i actually like it. lol

 

when driving the v2 sucking sound isnt 2 loud compared 2 my friends DC2 with J's racing intake

but i like that sucking sound rofl =\

but none the less even though it gets louder i love it, has a nice deep sound 2 it
