Description

The AD‑A403 is a precision-engineered cold air intake system designed for the B9 Audi A4/A5 (2015 onward) 2.0 TFSI 40 TFSI model. It replaces the stock airbox with a performance-grade intake featuring a rigid heat shield, high-flow silicone piping, and a reusable dry cone filter — delivering improved airflow, reduced intake temperatures, sharper throttle response, and a deeper engine induction sound. These enhancements are achieved without altering the ECU.
