What's different about the air cleaner assembly on a Y82 Indy? (Page 1/1) ryantim76 SEP 30, 06:20 PM Hello, all. Strange and useless question perhaps, but can anyone tell me why the AC Delco parts catalog would list the A913C "polywrap" air filter (basically the severe duty verison of the A785CF) as usable in all 2.5L Fiero applications "EXEPT LIMITED Y82"? Other than the silver color and graphics, I had assumed there's nothing different about the air cleaner in an Indy versus standard? Any ideas?
