Challenger, Champ, Colt and Sapporo

The air injection system consists of an air line from the air cleaner which enters the exhaust system between the catalytic converters. A pulse air feeder, mounted in the line, consists of main and sub reed valves. The system supplies secondary air into the exhaust manifold to promote oxidation of exhaust emissions.
