okay i have a short ram intake with a k and n filter on it and when i step on the gas prob around 30 40 percent with the windows open i hear a loud like shhh and wistle sound coming from under the hood...im i the only one with this sound or?? do i have a intake leak or sumthing or is that just normal...its really loud and annoying

 

Mine whistled too when I had it, but it wasn't that bad. You have the 00VI too right? I think I read somewhere that if you removed the restrictor plate that's behind the TB in the IM, it can cause a bad whistle too.

 

I have the Stillen intake and I do hear a very slight whistle just when I step on the gas, but it's nothing compared to the PSHEW that I heard from the Autozone rice-cone I had on my old car. I heard those where just normal sounds from cone filters. I could be wrong though.

 

i have my restricter plate in...should i take it out?? is it better if its out?? and yeah this is like a loud shhhhhhh and wistle mmixed i think im mite have a leak sumwhere or sumthing but idk where

 

Take it out & see if it changes at all. It's worth a shot if the noise is really bothering you.

 

The whistle is normal, almost everyone has that, but im not sure about the pshhhh....might be a leak.

 

Its the midpipe that makes the whistle not the filter.

 

mine whistles too. its b/c you probably removed the mixing box when you put in the intake. its normal and non threatening to the car. where is the restrictor plate behind the throttle body?

 

but doesn't any kind of leak after the MAF Sensor make the car dump wrong amount of gas??

my maf is in the front after the cone.. i took everything out... i still hear a phssss sound.. but only because of a hole that is partially plugged up.. iono what that is suppose to hook up to.

can anyone help me?

 

I just did the Stillen Hi flow intake as well and mine has the SHH sound as well when I get on the gas. Mine does not whistle. I to would think if you get the whistle it would be an air leak.

The one thing I thought strange was the Stillen instructions talked about the 2 parts to the air intake box and that their Hi flow system would replace that. However the Air collector that is attached to the frame near the radiator with two push pins and the condensation box at the bottom of the bent tube that would go into the bottom piece of the air intake box was not mentioned to be removed. I took them out and just relocated my boost sensor that was just attached the Air collector piece.

Is everyone else doing this as well or not?
