Before you order

- In California and other CARB states a replacement converter needs an Executive Order number for the specific vehicle.
- Check the retailer listing for whether engine software changes are required.
- Listings are read from the retailer's 8Y RS 3 (2.5T, quattro) category. Confirm engine, drivetrain and model year on the retailer page before ordering.
