I used to have RM racing CAI, the problem is when I acceleration between 1000-4000 rpm shortly ringing noise from CAI or throttle body I don't know which one. After a month I bought weapon-r CAI make same noise like RM racing CAI.
Have anybody have any problem with CAI like mine.

I don't think the CAI caused the ringing sound. Definitely something else. Like you said after using another CAI, the ringing sound is still present.
