Advanced Flow Engineering, Inc. (aFe) produces high flow, high performance air filters & intake systems for the automotive industry. Founded in April, 1999, aFe was created to address an obvious need in the automotive aftermarket industry: a lack of choice for a high performance aftermarket air filter.
Comprised of a team of engineers, machinists, production and sales people with a strong belief in the products they design, aFe’s team has years of experience in their respective positions and together work to ensure that they have the best products on the market. Rather than just to be another vendor that offered air filters, they chose to pay attention to those finer details that set an aFe product apart from the competition.
