AEM was one of the first companies to design performance aftermarket induction systems with specific tube lengths and diameters. The design took 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 has been a leader in the development of precision tuned induction systems since the Battle of the Imports. Today, the Company’s induction systems number in the hundreds. AEM is still the one to beat.
