Replacement air filter for the Alpha Mercedes-Benz AMG M157 / M278 Carbon Fiber Intake System. In our design, the cross-sectional area of the air box filter was increased by a massive 41%. It is considerably larger and provides your AMG with improved air flow dynamics for greater efficiency and maximum output!
PLEASE NOTE: This is a replacement filter for the Alpha Performance Intake System. This filter requires the Alpha intake system and is not directly compatible with the factory air box.
