K03 Turbocharger

The Stigan 847-1001 is a K03 turbocharger engineered as an exact-fit replacement for the factory unit on specific 1.8L turbocharged vehicles. By reverse-engineering the original design to correct common performance and durability issues, this replacement ensures proper engine operation and efficiency. It is intended strictly as a direct swap for vehicles originally equipped with this turbocharger system and is not compatible with vehicles that did not come with a turbocharger from the factory. This turbocharger is specifically designed to fit the 1997-2006 Audi A4 1.8T and the 1998-2005 VW Passat 1.8T. Crucially, this part does NOT fit Golf, Jetta, or Audi TT models, as the mounting configurations for these vehicles are significantly different, even when equipped with similar 1.8L turbocharged engines. Each unit is painted for durability and is subject to rigorous testing before leaving the factory. It comes with a two-year, unlimited-mileage warranty to ensure peace of mind during installation and daily operation.
