Advanced Flow Engineering, Inc. (AFE) produces high flow, high performance air filters & intake systems for the automotive industry. Improve both airflow and air quality with an AFE intake system, and thus improve your vehicle's performance and mileage.  AFE provides several levels of air filters and intake systems to suit every need. The AFE Super Stock intake system retains the factory airbox but replaces the filter and the intake tube.  The AFE Magnum Force Stage 1 and Stage 2 systems replaces the factory airbox, the air filter and intake tube for maximum performance. In addition to AFE's standard replacement filter, you can also choose the Pro-Guard 7 for the best performance, or the Pro-Dry S filter (with no oil) to prevent sensor clogging. Whether you drive a gasoline or diesel vehicle, AFE can make it drive better than ever!
