Hey guys, today I noticed my car making a hissing noise when I accelerate inthe lower rpm area. I have the sx auto with a tk cai. It kind of sounds like its coming from the cai so I'm thinking it may have cracked or ripped on the filter? It almost can sound like a screech when its high pitched, so my friend suggested it may be a belt. I'm thinking of taking it to the dealership. Anyone have any similiar issues? Any suggestions? Thanks.
