ok as far as i can remember (pretty sure) that this weird noise came after i installed my Bomz CAI

at around 3k rpms it starts to make a high pitch whistling noise coming from under the hood on the CAI's side, but as soon as go any higher or lower of rpms the noise goes away.

the noise is very annoying and only lasts for a sec cuz i usually step on the throttle to make it go away but im just wondering if anyone has any ideas such as something wrong with a Bomz filter and im thinking i should upgrade anyway to a K&N filter

 

Thats the normal noise a cai makes.

 

Umm... Neither my CAI or SRI have ever made a high pitched noise so... maybe you shouldn't have bought something from BOMZ?
