BorgWarner Audi 1.8T Transverse 1.8L K03 Turbocharger

This is a BorgWarner K03 turbocharger specifically for Audi 1.8T Transverse 1.8L engines. If your factory turbo is worn out or you're looking to replace it with a well-built unit from a trusted name, this is a solid option. BorgWarner has been a major player in turbocharger technology for a long time, and this K03 is built to meet the demands of your 1.8L engine.

The K03 is a popular turbocharger for many 1.8T applications, known for providing a good balance of responsiveness for daily driving and the ability to support moderate power increases. This unit is designed as a direct replacement for your original turbo, meaning it should bolt up to your existing exhaust manifold and downpipe with the proper adapter or flange. It features a cast iron turbine housing and an aluminum compressor housing, typical for this size and application. The internal wastegate actuator is pre-calibrated to help maintain proper boost pressure control right out of the box.

When installing a new turbocharger, it's crucial to ensure your oil supply and return lines are clean and free of debris. Also, make sure to prime the new turbo with oil before starting the engine to prevent damage during initial startup. This turbocharger is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for detailed procedures and any specific hardware or gaskets that may be required for your vehicle.
