CTS Turbo 4″ Turbo Inlet Pipe for 8Y Audi RS3

The CTS Turbo Cast Aluminum 4″ Turbo Inlet for the 2022+ Audi 8Y RS3 2.5T (DWNA) is a high-performance upgrade engineered to dramatically improve airflow to the turbocharger by replacing the restrictive factory turbo inlet. As the first 4″ inlet designed specifically for the updated 8Y RS3 with the additional PCV connection, this inlet features a massive 78% increase in volume over stock, ensuring the 2.5T engine receives the air it needs to perform at its highest potential—especially when tuned or running increased boost. Developed using state-of-the-art 3D scanning and rapid prototyping, the cast aluminum body is precision-machined in-house to ensure seamless OEM fitment to the factory turbo, and it includes a PCV relocation kit for proper crankcase ventilation without triggering a check engine light. Compatible with most aftermarket intake systems using a 4″ coupler, this upgrade is not designed to work with the factory intake pipe; however, CTS Turbo offers a matching high-flow intake pipe for stock airbox setups. With its large internal volume, optimized flow path, and durable construction, the CTS Turbo 4″ Inlet is a must-have upgrade for RS3 owners seeking maximum power and performance from their 2.5T engine.
