I bought an 81' Z28 about 2 years ago with cowl induction. I started going over the air cleaner assembly and came across something I haven't seen before. It looks like a smaller air cleaner inside the main air filter. I'm not even sure this is the correct air cleaner assembly for my car since the motor isn't orriginal. I've taken some pictures of it. Any help or info anyone can give me wold be appreciated.
