Default Air Filter Cover

Removed the cover to check the filter, 1985 model. Noticed as I reinstalled it that it has louvers. Question is do the louver openings face down toward the road such as this, ^^^^^^^ or toward the hood like this, vvvvvvvvv? Or does it even matter? I faced them down btw. TIA for putting up with a newbie.

good question, on my 85, I've always installed the filter cover with the louvers, in what you're calling, face down (if i'm reading you right), or this "^^^^^^^." not sure it matters though, since each (long) side has two small "weep" holes at each corner. face down would make more sense if you consider airflow. might need "ihatebarkingdogs" input on this one.

Think I found my answer in this older forum thread. https://www.corvetteforum.com/forums...xperiment.html I may have described it wrong. I checked and my cover is installed the way it is shown in the thread so I believe I have it right.

OK, from the (before) pic, that's the way mine is installed - assuming that's correct.
