About 3K Turbos

Today, BorgWarner Turbo Systems is a combination of two turbocharger manufacturers with a history rich in turbocharger design, development, and application. 3K Turbochargers (a.k.a.

Today, the K-Series (of 3K decent) turbochargers are still used in a variety of applications by BorgWarner.

For passenger or commercial vehicles, industrial, locomotive or marine engines: whatever the application, BorgWarner Turbo Systems has just the right turbocharging system for you.
