BorgWarner Turbocharger SX K03 Audi/VW 2.0 TFSI Replacement

This BorgWarner K03 turbocharger features a 53mm compressor wheel inducer diameter, a key spec that helps it perform as a direct replacement for the factory unit on Audi and Volkswagen 2.0 TFSI engines. When your original turbo starts to lose its boost or develops leaks, replacing it with a well-built unit like this BorgWarner can restore lost power and responsiveness. It’s designed to bolt right into the existing exhaust and intake plumbing, simplifying the installation process for mechanics and DIYers alike.

Built with BorgWarner's experience in forced induction, this turbocharger uses robust materials and precise manufacturing to ensure reliable operation. The turbine housing is cast from a durable alloy capable of withstanding high exhaust gas temperatures, while the compressor side is designed for efficient airflow to build boost quickly. This unit is a popular choice for those looking to replace a worn-out factory turbocharger and get their vehicle back to its original performance levels. It’s important to ensure all supporting systems, like the oil and coolant lines, are clean and in good condition before installation to protect your new turbo.

This turbocharger is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper procedures, including any required break-in periods or specific oil requirements to ensure the longevity of the unit.
