AC was introduced in the middle of the 1963 model with only 278 cars so equipped, making these the third most rare of '63s (36 gallon tank cars and Z06 being fewer) and more rare than many other cars. In later years, the number grew to where AC became standard equipment. No '53 to '62 Corvettes had air conditioning from the factory. AC Cobra See Cobra, AC Cobra, Shelby Cobra. AFB See Carter AFB. A.I.R. In terms of emissions equipment, this stands for Air Injection Reactor. Air is pumped by the "smog pumps" through air injection manifolds into the exhaust manifolds to complete the oxidization process of the unburned hydrocarbons in the exhaust stream. Many claim this is hogwash and is simply a case of diluting the exhaust with fresh air. That is, if the exhaust dirt is 100 parts per million (PPM), then adding a million parts of fresh air effectively makes the exhaust dirt 50 PPM, reducing the dirtiness, even though the same amount of dirt is still present. In terms of racing, this stands for the American International Racing team headed by James Garner in 1968. His team bought three new 1968 L88 Corvettes for racing and ran them in the late '60s. Air Box In the late '50s, part of the racing options included a box for channeling air through the body to the rear brakes for cooling.
