For the automotive enthusiast who want all the power and torque he can get, aFe designed the top-of-the-line Magnum FORCE Stage 2 cold air intake system.

For powered enhanced vehicles, whether equipped with turbocharger, NOS, propane, performance module; without more air, you are not getting maximum power. The Magnum FORCE Stage 2 systems provide all the air you need. Compared to our other systems, the Magnum FORCE Stage 2 intake system replaces the entire stock air induction system to the throttle body or turbo housing. Remembering our motto “Stock Sucks”, we eliminate the stock air box, the stock air filter and the stock intake tract. The only thing retained is the stock electronics. We make sure that our Stage 2 system like all our intake systems works with the stock electronics.
