      The AEM Story

      AEM was founded in 1987 by John Concialdi (J.C.) and Bob Sullivan as a tuning performance shop. The shop focused on vintage automobiles and the latest trends in street racing modified imports. With it's location in Compton California, AEM was embedded in the tuner market from the very beginning. It was a matter of being in the right place, at the right time, with the right technical knowhow. Between J.C. and Sullivan, AEM had two important advantages. Technical engine knowledge and massive creativity fueled by an unbridled passion to make things go faster. When it came to understanding air flow through an engine, few had more experience than Concialdi. He managed the R&D department for Weber Carburetors for North American aftermarket applications the previous 10 years. By 1993 when the shop relocated to Gardena California, AEM had the reputation as a modifier of choice. The business had grown so much that at times it ran 24 hours a day. Racers depended on AEM to have cars ready for the next street race or sanctioned event. Cars and drivers sporting AEM’s bright yellow logo became famous in the street racing scene for one consistent reason, they won races. AEM’s first glimpse of mainstream notoriety came when cars tuned by their shop won at the “Battle of the Imports”. This highly contested shoot-out landed AEM on the cover of Turbo Magazine and Sport Compact Magazine. Many of the most visible drivers in import street racing ran cars modified by AEM. This included names like Adam Saruwatari, Tony Fuchs, Brian Kim and Darin Ishitani, Archie Medrano, Russ Matuseavich, Abel Iberra, Miles Bautista, E.T. Saffon.
