Filtration, airflow, and heat are the three factors that matter most when designing an intake system for a turbocharged engine, and the factory setup on the Polo GTI (AW) and Audi A1 40 TFSI (GB) leaves genuine room for improvement across all three. A restrictive filter element and factory ducting both limit airflow reaching the turbo, while the airbox's position in the engine bay leaves it exposed to radiated heat that raises intake air temperatures under sustained hard driving.
do88's replacement addresses this with a sealed design that keeps hot engine bay air out while opening up genuinely improved airflow through the system. This kit bundles the intake system together with a matched turbo inlet pipe, ensuring the entire path from filter to turbo is properly sized and coordinated rather than mixing an upgraded airbox with a restrictive factory pipe downstream.
Please select your turbo inlet pipe at checkout: do88's own 76mm pipe for maximum airflow, or an OEM-matched version if you'd prefer to retain factory-style connections elsewhere in the system.
