It can apply to both. The older 69 Trans Am's came with stock ram air and some of the 70 GTO's did also. A major plus for any ram air setup is the extra pressure at high speeds but another big plus at any speed is using cooler air, for every 10 degree cooler you see 1% Hp gain or 2% with a turbo. Ram air was used quite a lot back in the late 60's early 70's on the pony cars and Vetts.
