My caprice being an 83 doesnt have this, and apparently it has no means of air filtration. One day i was driving on a highway that was being re-paved...a lot of tar particles were getting kicked up and all after it switched to paved road, i was coated in the stuff! The AC was on low too, and luckily nothing got in my eyes! So i was wondering if i'm actually suppose to have some sort of filter under that plastic grate in front of my windshield or is this normal?
