4. Ram Air Induction
Ram Air marks the induction system characterized by the openings on the car’s hood, grille or even below the bumpers in some Oldsmobile models. They design it to feed fresh air to the engine. Almost all muscle car manufacturers produced some kind of Ram Air device. However, Pontiac was the most famous for naming its system, “Ram Air.” They marketed it as a special performance package on the GTO and Firebird/Trans Am models.
They presented this option on the 1967 GTO until the mid-70s. There are some reports that it was available in 1966 as a dealer-installed option. But factory documents show that it was available to the public from 1967. Today, the Ram Air is a desirable option to have on your classic GTO or Firebird.
