AFE Magnum Force Stage 2 Cold Air Intake System
Looking to take your car to the next level? Tired of other intake systems that just look good on paper? AFE (Advanced Flow Engineering) intakes are the solution for you! For the enthusiast that's looking for all the power and torque you can get from an intake system; AFE 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.
