aFe believes that “stock sucks” – meaning that the stock parts that
come pre-installed on your vehicle are not necessarily the ones that will be
the best for power and quality.

To attain high-end performance for your Audi , aFe recommends the
Magnum Force Stage 2 Intake System which replaces the entire stock
air induction system – all the way to the throttle body or turbo housing.

Here are some of the notable factors why you should consider getting
an aFe Magnum Force Stage 2 Intake System for all Audi vehicles:

Features
• Stage 2 Provides Maximum Performance.
• Replaces Entire Stock Intake Path.
• Si Features Sealed Airbox with Ram Air Scoop.
• Filter Lasts the Life of Vehicle.
