Polymer Air Intake System

The Integrated Engineering polymer air intake system is engineered to optimize airflow for the Audi B9/B9.5 A4 and A5 models equipped with the 2.0T engine. This upgrade aims to release a more audible symphony of engine throttle, spool, and blow-off sounds. Key design elements include high and low-pressure zones to meet varying engine demands and an integrated velocity stack that smooths airflow into the charge system, reducing turbulence and drag at the turbocharger inlet. Flow bench testing indicates airflow gains of up to +70 CFM over stock, with power gains of up to 10-20HP reported on tuned engines. Installation is designed to be hassle-free with basic hand tools, typically taking 20-30 minutes due to its direct factory upgrade nature and stock-style mounts. This system is compatible with 2017-2024 Audi A4 and 2018-2024 Audi A5 models featuring the 2.0T Turbocharged engine. However, please note that this IE intake system does not fit ROW (Rest of World) vehicle engines equipped with a MAF sensor; verification is recommended before ordering.
