So I took my intake silencer off and it sounded great for the first week. But now, whenever my rpms are between 2000 and 2500, the intake starts to hiss. Is there anyway to fix this without installing a CAI or putting the silencer back in? Also, could putting a new air filter do anything to stop the hissing?

 

its very common of a CAI to have a slight whistle at that RPM range

 

but i dont have a CAI installed. Im just wondering if theres anything i can do beside install a CAI or putting the silencer back in to stop the hissing.

 

Come on.......Any suggestions would be very appreciated

 

Are you sure its the intake. My car (with a CAI) makes a noise from the passenger side that is not the CAI... That noise is alot more annoying.

You will get even more hissing with the CAI. If you dont like it you will have to install the silencer.
