Key Product Features

• 100% Brand New: This is a zero-mileage unit. Every part—including the housing, internal core (CHRA), and wastegate actuator—is factory-new.
• Simplified Wastegate Design: Matches the original AGR specification for superior reliability and easier maintenance compared to variable-geometry (VNT) models.
• VSR High-Speed Balancing: Every unit undergoes precision balancing at high RPMs to eliminate vibrations, ensuring quiet operation and maximum bearing life.
• Heavy-Duty Castings: Built with high-nickel alloys to resist cracking and warping under the thermal stress of long-distance driving.

Essential Installation Tips

To protect your investment and ensure long-term performance:

1. Fresh Oil & Filter: Always perform a complete oil and filter change during installation. Use a 5W-40 or 10W-40 oil that meets VW 505.00 specifications.
2. Prime the Turbocharger: Before the first start, fill the turbo’s oil inlet port with clean engine oil and manually rotate the compressor wheel to ensure the bearings are lubricated.
3. Inspect Oil Feed Line: Check the oil supply pipe for carbon buildup or restrictions. If in doubt, replace the line to prevent oil starvation.
4. Air Intake Check: Ensure the air filter is new and the intake path is free of debris from the previous turbocharger failure.
