hey guys i just installed my stillen high flow intake and a z-tube today and i was wondering like when i hit round... 4200 rpm i can hear a bit of a high piched noise but when i shift it goes away until i hit that rpm again... is that ok?? just want to be sure everything is workin fine... also the kit came with a K&N air filter to go with it.. thanks!!!

 

intake usually make noises. some sound as if you've got a small turbo or something under the hood. if you are uncertain of anything go back and look at everything and make sure it's all installed correctly but, usually intakes will make noises...throttle body spacers sometimes amplify the sound. they will all usually make a whistling noise tho.

congrats on the purchase btw. i've got the same intake only with an oem z tube. you will not be disappointed.

 

It's normal to hear a slight whissling sound when you have the throttle open at a certain position. I wouldn't stress it if I were you. a Rattling sound may be something to look into though.

 

^ exactly..

also if you want more noise about 25-40% throttle is where the moneys at =P at around 3-4,500rpm

 

ok guys thanks for the info but ya in my opinion it knida does sound like a whislte like a turbo but no rattling or shaking just wanted to be sure but ya i love this kit great power and makes the engine sound soo much deaper!! sounds amazing i would recommend it

check it out!!!!!!!!!!!!!

 

Love the Stillen CAI/Z-Tube combination! No issues with heat soak and with the K&N filter there's no better intake for our coupes. I keep mine as a backup for trips when I want to roll without loss of rwhp due to heat....Gary

 

^ I remember a long time ago I modded a stillen intake to fit a JWT PopCharger.. it sounded more awesome.. but I had to do some cutting to make it fit.

If you want more noise you can probably look at a M7 Japan Intake.. Those things are beast
