Fresh Air intake Inconsistencies
Starting in 1973 the Trans Am hood scoops were closed. Yet, you could still get the ram air air cleaner on Formula's through 74'. Also, the 1974 GTO hood scoop was functional.
Why would Pontiac have fresh air intake on the GTO and Formula's but not on the Trans AM? I had read somewhere that it was due to some EPA noise rule. If that is true, how did the other's pass the rule?
