Improve the airflow in your Audi A3/S3, TT or Volkswagen Golf/GTI/R and ditch the OEM charge pipe as it just does not cut it for flow. 

The AMS Performance Turbo Charge Pipe AMS.21.09.0003-1 one piece design with large radius bends, an 85% larger inlet, and almost 10% larger outlet removes the bottleneck in the charge air system is a great improvement over OEM.  This direct bolt on kit has fitment as good as OE.
