Key Product Features

• 100% Brand New: Zero-mileage unit. Every component, from the high-temp turbine housing to the precision-milled compressor wheel, is factory-new.
• Bi-Turbo Precision: Specifically calibrated to work in harmony with the larger low-pressure turbo, ensuring a seamless power curve and no "turbo lag."
• VSR High-Speed Balancing: Balanced at speeds exceeding 150,000 RPM to ensure vibration-free operation and maximum bearing life under heavy commercial use.
• Advanced Metallurgy: Manufactured using high-nickel alloys to resist the extreme heat generated in the compact high-pressure housing.

Critical Installation Requirements

The OM646 Bi-Turbo system is highly technical; please follow these steps to protect your warranty:

1. Replace Oil Feed Lines: The oil feed pipes for the Sprinter Bi-Turbo setup are prone to carbon buildup. Replacing these lines is mandatory to ensure the new bearings receive constant lubrication.
2. Oil & Filter Change: Use only high-quality synthetic oil meeting Mercedes-Benz 229.51 specifications.
3. Prime the Turbo: Fill the oil inlet port with clean oil and manually rotate the wheel before the first start to prevent "dry start" bearing damage.
4. System Seal Check: When replacing the "Small One," always inspect the gaskets and connecting pipes between the two turbochargers for boost leaks.
