This CNC-machined oil drain flange is the clean way to connect an AN10 return line to your turbo. Compatible with common VW/Audi turbo oil drain patterns (TDI, FSI, 1.8T), this adapter allows the use of braided lines for better reliability and easier routing.
Built from aluminum and anodized silver, it includes a machined lip and mounting holes to seal perfectly against the turbocharger housing. Makes DIY turbo builds or upgrades a whole lot easier—and leak-free.
Fitment: VW & Audi 1.8T, 2.0T FSI, and 1.9 TDI turbochargers using standard rectangular 2-bolt drain flanges.
