BorgWarner Turbocharger SX Audi A6/Allroad K03 CHRA Cartridge Assembly

What you get with this BorgWarner turbocharger assembly is the core rotating assembly, often called the CHRA (Center Housing Rotating Assembly). This is the heart of your turbocharger, containing the turbine and compressor wheels precisely balanced on their shaft. It's designed to replace the CHRA in your Audi A6 or Allroad's factory K03 turbocharger, giving you a fresh start for restoring boost and performance.

BorgWarner is a well-known name in the turbocharger world, and this CHRA cartridge assembly is built to meet the demands of your vehicle's engine. It's a solid option if your original turbo is showing signs of wear, like reduced power, excessive smoke, or unusual noises. Replacing just the CHRA can be a more cost-effective solution than replacing the entire turbo unit, provided the external housings are still in good condition. This assembly comes pre-balanced from the factory, which is critical for turbocharger longevity and smooth operation. Proper installation is key; ensure all oil lines are clean and that the turbo is properly lubricated before initial startup to prevent damage.

This particular cartridge is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation guide for specific procedures and torque specifications to ensure a successful rebuild of your turbocharger.
