It's very effective. Chevrolet did the cowl plenum in 67-68 on the Z before eventually moving it to the rear of the hood in 69.

There are ram air boxes made of fiberglass now, I believe the company is "ram air boxes" and they do have a cowl plenum setup that accepts a 14" filter element, bolts on like a factory air cleaner. Just have to make the hole in the firewall and fasten with the rubber sleeve and you're there.
