Eventuri PCV Breather Adapter Kit - Audi C8 RS6 / RS7 2023-UpEventuri's C8 RS6 RS7 Carbon Intake System delivers on all fronts and allows for the turbos to generate boost more efficiently; however, for the 2023 Up model years, the Audi C8 chassis used a slightly different PCV connection at the inlet. If you've purchased a used C8 intake system initially purchased prior to 07 2023 and are installing on a 2023 Up model year, this breather vent adapter kit is required.
