AEM Induction Systems located in Hawthorne, California is a manufacturer of performance air intakes and air filter products, engineered to outperform. AEM was founded in 1987 by John Concialdi (J.C.) and Bob Sullivan as a tuning performance shop catering to vintage automobiles and the latest trend in street racing modified imports. Innovation has always been AEMs core competency! AEM was one of the first companies to engineer & design performance aftermarket induction systems with specific tube lengths & diameters to take advantage of pressure waves in the inlet tract. The tuning of the inlet tract dimension creates more control over the RPM range being affected. AEM began to explore the advantages of cooler air on combustion efficiency way back in the mid nineties and coined the phrase Cold Air Intake. AEM worked with K&N in 1999 to design conical air filters with built in air horns at the filter base to greatly enhance air flow into the inlet duct. AEM developed the first dual chamber intake kits designed to generate more power over a broad RPM range. AEM designed a unique air bypass valve in order to avoid hydro-lock situations for systems where the filter is low enough to encounter water at certain times. AEM created one of the first hybrid induction systems for cars with engine swaps. AEM has developed an electronic solution to MAF sensor scaling problems when using non stock inlet system dimensions for additional power.
