You will need to get an air cleaner for an E2ME carb, which is what is pictured. Easier said than done; this carb was a 'bastard carb' being the primary only section of a Quadrajet, and being fitted on vehicles from about 1978 to 1982 and usually on V6's or small V8s (i.e. 267 cubic inch).
There are no aftermarket air cleaners or filters for these that I am aware of.
